The rainforests of Sarawak in Malaysia on the island of Borneo are some of the richest and most biodiverse ecosystems on earth - but for decades they've been under threat from commercial logging, permitted by the Malaysian government. In the 1980s, local people from the Penan and Kelabit ethnic groups began to fight back against the logging, setting up blockades and appealing to international environmental groups for support. Their campaign would make headlines around the world.Lucy Burns speaks to activist Mutang Urud, who helped organise the blockades and later went on a world tour to attract attention to their cause.PICTURE: Tribespeople with spears block the road as plantation company vehicles approach a blockade in Long Nen in Malaysia's Sarawak State in August 2009.

On 16th October 1995 hundreds of thousands of African American men marched on Washington D.C. in an attempt to put black issues back on the government agenda and to present a positive image of black men. Aquila Powell – 23 at the time – was one of the few women who attended the march. She was working for the National Coalition on Black Voter Participation and trying to encourage attendees to register to vote. She talks to Ben Carter about her recollections of that day.(Photo:The Million Man March, Credit:TIM SLOAN/AFP/Getty Images)

On 20th July 1944 Colonel Claus von Stauffenberg put a bomb under Adolf Hitler's desk. Although the bomb exploded, it failed to kill the German Nazi leader.

A so-called Social Purification project led to thousands of ordinary citizens being imprisoned under the military government in South Korea in the 1980s. Under the pretence of clearing the streets of vagrants and undesirables, people were sent to camps disguised as 'social welfare centres' where many of them suffered torture, forced labour, and physical and sexual abuse.

During World War Two, thousands of Chinese sailors and engineers served in the British Merchant Navy, keeping supplies flowing into the port of Liverpool and risking their lives in crossings of the Atlantic. Many settled in the port city and started families with local women but, after fighting ended in 1945, the British authorities began forcing them to leave. Simon Watts talks to Yvonne Foley, whose Chinese father was pressured to return to Shanghai, never to be seen again.PHOTO: Chinese sailors in Liverpool in 1942 (Getty Images).

The Stele of Axum, a 4th century Ethiopian treasure, was finally returned by Italy in 2005. It had been taken from the ancient town of Axum in northern Ethiopia by invading Italian fascist forces in 1937. The huge 24 metre tall stele was originally erected to mark the site of a royal tomb during the Kingdom of Axum. The Axumites were a powerful and sophisticated civilisation which emerged in northern Ethiopia more than 2000 years ago. Alex Last spoke to Ethiopian archaeologist Tekle Hagos of Addis Ababa University about the return of the great monument.

Holidaymakers arrived at the first Club Med resort on the Spanish island of Majorca in summer 1950. The French company - full name Club Méditerranée - was founded to offer a new kind of post-war holiday by Belgian water polo player Gérard Blitz, who believed that "the time to be happy is now". The facilities were initially rudimentary, with guests sleeping in huts and sharing tables at meals - but the all-inclusive holiday model they pioneered soon spread all over the world.Lucy Burns speaks to Pierre-Xavier Bécret, whose parents worked on that first Majorca holiday and went on to be involved with Club Med for many years.Picture: postcard image of the Club Med resort in Corfu, 1970s (Editions Intercolor, with thanks to www.collierbar.fr)

In 1988, a group of Jewish feminists demanded the right to pray as freely as Jewish men at one of Judaism’s holiest sites. They called themselves the ‘Women of the Wall’. The organisation is made up of every Jewish denomination including reform, conservative and orthodox Jews. Its focus is one of the holiest sites in Judaism - the Western Wall in Jerusalem. Rachael Gillman has been speaking to Anat Hoffman, one of the founding members of 'Women of the Wall'.(Photo: Members of 'Women of the Wall' praying at the Western Wall in Jerusalem, holding their prayer shawls.

In the summer of 1967 more than 100 cities in America were caught up in riots. US Senator Fred Harris urged the President, Lyndon B Johnson, to investigate the causes. He set up the Kerner Commission and appointed Fred Harris as one of 11 members to find out why America was burning. The final report shocked many Americans when it blamed white racism for creating and sustaining black ghettos. It said the US was dividing into two separate and unequal societies - one black and one white. Claire Bowes has been speaking to former US Senator Fred Harris.Photo: Members of the Kerner Commission giving final approval to the panel's report on 28th February 1968. Senator Fred R.

When Montreal's police force went on strike for one day over pay in 1969, there was looting and rioting in the streets. But the city's problems leading to the unrest had been building for more than a decade. Organised crime, militant separatists and commercial rivalries all erupted on 7th October, just as police officers decided to protest that their pay was much lower than officers in other Canadian cities. Sidney Margles was a local reporter, and described the scene, and the underlying problems, to Rebecca Kesby.(PHOTO: The scene at the Murray Hill Limousine garage as rioting left several buses on fire and damage to property, following a police strike in Montreal.

The black former soldier choked to death in handcuffs on the floor of a British police station in 1998. CCTV footage taken from the police station showed the 37 year-old father of two gasping for air as officers chatted and joked around him. It took 11 minutes for him to stop breathing. An inquest found he was unlawfully killed but no-one has been held accountable for his death. Farhana Haider speaks to Janet Alder about her long fight to get justice for her brother.Photo:Christopher Alder an ex paratrooper who died in a police station in Hull on 1 April 1998.

In the 1800s cholera was a mysterious disease killing millions around the world. No-one knew how to stop it till an English doctor, John Snow, began investigating the outbreak of 1854. At a time before germ theory was properly understood, many public health experts thought disease was carried on what they called "bad air". John Snow was alone in thinking cholera was spread through contaminated water and by the time of his death - in 1858 - his theories had still not been fully accepted. Claire Bowes spoke to Dr Nigel Paneth, a biographer of John Snow, about the skills he brought to the developing science of epidemiology.Photo: Portrait of John Snow (Science Photo Library BBC)

In 1990, South Africa became the first country in the world to ban skin-lightening creams containing the chemical compound hydroquinone. For years the creams had caused an irreversible form of skin damage called ochronosis for the black and Asian South Africans using the products. Rachael Gillman has been speaking to Dr Hilary Carman, one of the activists who worked to ban the creams and Dr Ncoza Dlova who became one of the country's first black dermatologists.Photo: A woman applying a skin-lightening cream to her face.

In 2012 a stunning, secret collection of art was found in Germany. Much of it had disappeared during Nazi rule in the 1930s and 40s. It had once belonged to one of the Nazi's top art dealers, Hildebrand Gurlitt. It was found by chance in the Munich apartment of his elderly, reclusive son, Cornelius. It contained lost works by Renoir, Matisse, Chagal and the masters of the German expressionist movement. Many of the works had been confiscated during the Nazis "Degenerate Art" campaign in the late 1930s, when the Nazis stripped thousands of works of art from public display. Alex Last spoke to Dr Meike Hoffmann, an expert on Nazi art policy, who was one of the first to examine the collection. Photo: One of the art works discovered in the Gurlitt collection was Pferde in Landschaft (Horses in Landscape) by famous German expressionist Franz Marc.

What it was like to be a child quarantined in a sanatorium for tuberculosis patients in the 1950s. Ann Shaw was nine when she was first admitted to the Craig-y-nos sanatorium in Wales and 13 when she was finally allowed home. Until antibiotic treatments came along, to stop the disease spreading, TB patients were kept apart from the general population and their families, often for years. This included babies and children, leaving many traumatised. Ann Shaw tells Louise Hidalgo about the half-life they lived in the sanatorium.Picture: boys on the balcony of the Craig-y-nos TB sanatorium; fresh mountain air was regarded as one of the best treatments for TB (Credit: from the private collection of the family of Mari Friend, a former patient at Craig-y-nos)

Mick Jagger and Keith Richards went on trial for drugs offences in June 1967. The case attracted attention around the world, and sealed their reputation as rebels. The men were originally sentenced to prison but on appeal their sentences were drastically cut and the trial came to symbolise Britain's changing values.

A people’s movement called Jana Andolan brought an end to Nepal’s absolute monarchy in the spring of 1990. Political parties worked together with students, workers and civil society groups to organise strikes and street protests – but although the king eventually agreed to their demands, it was the beginning of a long period of political instability. Lucy Burns speaks to activist and writer Devendra Raj Pandey about his memories of the first Jana Andolan.PHOTO: Jubilant protesters take to the streets on April 9, 1990 in Kathmandu after the government announced an end to the 30-year ban on multi-political parties.

Following the violent military coup that overthrew Chile's socialist government in 1973, the new regime led by General Augusto Pinochet began a radical overhaul of the economy. It was based on a free-market economic plan created by a group of economists known as the Chicago Boys. Mike Lanchin has been speaking to one of them, Rolf Lüders.Photo: General Augusto Pinochet (L) poses with socialist Chilean president Salvador Allende (R) in Santiago, just after Allende appointed him the head of the army, and only three weeks before Pinochet's military coup in September 1973.

In the late 1960s Tanzania's first post-independence president, the charismatic Julius Nyerere, believed that endemic poverty in rural areas could only be addressed if peasant farmers relocated to larger villages and worked collectively. It was part of a new experimental form of socialism, known as Ujamaa. In 2016 Rob Walker spoke to two Tanzanians who remember it well.This programme is a rebroadcast.Photo: Tanzanian women cultivating the soil (AFP/Getty Images)

An eyewitness account of how a poor, war-ravaged nation became a global economic powerhouse. We hear the memories of Dr Kongdan Oh, who grew up in South Korea in the 1950s, in the aftermath of the Korean War. The country had been left devastated by the conflict. Then, in the early 1960s, South Korea's new military leader, General Park Chung-hee, launched an ambitious national drive for rapid economic growth. For many, it marked the start of South Korea's economic transformation. Photo: South Korean labourers balancing baskets of coal, while working inside the grounds of a factory.

When Dr Martin Luther King was assassinated in 1968, US school teacher, Jane Elliott, decided to try to teach her all-white class about racism. She decided to segregate them according to the colour of their eyes, and treated them differently. Although controversial from the start, the “blue eyes/brown eyes” teaching exercise has been adapted in schools and workplaces for diversity training ever since. Jane Elliott has been explaining to Rebecca Kesby why she still thinks the model has value today in defeating racial prejudice.

The passenger train service between India and Bangladesh was resumed after more than 40 years. The train service had been suspended after the 1965 war between India and Pakistan of which Bangladesh was then a part. Partitioned in 1947, Bengal was divided in half between Hindu majority India and Muslim majority East Pakistan. Families were torn apart. East Pakistan later become Bangladesh after gaining independence in 1971. The Maitree or Friendship Express was the first passenger train service to connect the two Bengals in 43 years.

In the late 1990s, whistle-blowers implicated UN peacekeepers and international police in the forced prostitution and trafficking of Eastern European women into Bosnia, which was just emerging from a bitter civil war. Louise Hidalgo has been talking to one of those who sounded the alarm, British human rights lawyer, Madeleine Rees, who was then working for the High Commissioner for Human Rights in Bosnia.Picture: the United Nations Peacekeeping Force patrols the Bosnian capital Sarajevo in March 1996 (Credit: Roger Lemoyne/Liaison/Getty Images)

During the early years of Cultural Revolution in China, all European music was banned. Even enjoying traditional Chinese music and art was illegal. Anyone found with old instruments or recordings could be imprisoned. But that didn’t stop some musicians and enthusiasts from playing or listening to the music they loved, sometimes as an act of rebellion. A favourite during those times in China was the German composer – Ludwig Van Beethoven. Conductor, Jindong Cai tells Rebecca Kesby how he decided to become a musician after listening to an illegal recording of one of his symphonies.(Portrait of German composer Ludwig van Beethoven (1770 - 1827) by German painter Joseph Karl Stieler, 1820.

Denial. Anger. Bargaining. Depression. Acceptance. When Swiss psychiatrist Elisabeth Kübler-Ross published her bestselling book On Death and Dying in 1969, she described a series of emotional stages that she had seen terminally ill patients experience – later known as the Five Stages of Grief. But there was much more to her work in end of life care. Her son Ken speaks to Lucy Burns.Photo: Dr. Elizabeth Kübler-Ross, Virginia Farm, 1987. Photo courtesy of Ken Ross www.ekrfoundation.org

One man's experience of the controversial US law that saw thousands locked up for life. Under the law in California, a third conviction for a felony offence would lead to a life sentence. At times in California, 45% of "three strikers" were African American. Many were sentenced to life in prison for non-violent or minor offences.

In 1966, an all-black team went head-to-head with an all-white team for the National College Basketball championship - one of the biggest prizes in American sport. To much surprise, the African-Americans of Texas Western College defeated the University of Kentucky, then the number one team in the country. The game is now regarded as breaking the colour barrier in US basketball. In 2016 Nija Dalal-Small spoke to Nevil Shed, one of that groundbreaking Texas Western team. The programme is a Sparklab Production for BBC World Service.PHOTO: Texas Western celebrate their victory in 1966 (Getty Images)

In the 1960s, doctors in Northern Ireland launched the world’s first mobile coronary emergency service using a new invention – the portable defibrillator. The defibrillators – which initially worked off ambulance car batteries - saved dozens of heart attack victims every year. Modern versions are now commonly seen and used in places like offices and shopping malls. The man behind the portable defibrillator was Belfast hospital doctor Frank Pantridge. Simon Watts tells his story using the BBC Northern Ireland archives.PHOTO: A defibrillator in use (Science Photo Library)

The WHO was first proposed as part of the new United Nations programme to reform the post-war world. The idea for an international health organisation to help promote good health globally was put forward by a member of the Chinese delegation, Szeming Sze. His memoirs reveal the political difficulties which dogged the process and his son remembers his passion for the project. We also hear from historian, Professor Theodore M Brown on what was really going on behind the scenes.Photo: Official logo of the World Health Organisation 1950 (Getty Images).

The artist Christo died on May 31st 2020. Famous for wrapping landmarks in fabric and plastic, one of his most ambitious projects was the former German parliament building which sat on the border between East and West Berlin. It had been gutted by fire in 1933 and extensively damaged during the Second World War. In June 1995 Christo and his wife Jeanne-Claude completed the monumental public art project which was seen by more than five million people and became a symbol for Berlin’s renewal after the collapse of communism and the reunification of Germany.Christo spoke to Lucy Burns in 2019.

Just one month after gaining independence there was an uprising in Zanzibar in 1964. It was billed as a leftist revolution but the worst of the violence was ethnically targeted. Zanzibar’s complex history meant the islands were home to a very diverse population, and the legacy of the slave trade had left deep scars and lingering resentment. Ahmed Rajab was a student in 1964 and remembers the night the revolution broke out. He’s been telling Rebecca Kesby what it was like, and how it was a Ugandan man, John Okello, not a Zanzibari who lead the uprising.(PHOTO: Ugandan revolutionary and self-styled Field Marshal John Okello (1937 - 1971), leader of the Afro-Shirazi anti-Arab coup in Zanzibar which led to the country's independence, circa 1964.

During times of crisis in the UK, World War Two is often remembered as a period when the country rallied together to fight a common enemy. British politicians still refer to the so-called "Blitz Spirit" when calling for national unity. But as Simon Watts has been finding out from the BBC archives, there was a crime wave during the war years, with a massive increase in looting and black marketeering.PHOTO: A government poster from World War Two (Getty Images)

Ground-breaking work by developmental psychologist Professor Uta Frith has revolutionised our understanding of autism. Beginning in the 1960s, Professor Frith's research has overturned the long-held belief that autism was a social or emotional disorder, showing instead that it's the result of physical differences in the brain. Uta Frith has been talking to Louise Hidalgo.Picture: Uta Frith at her desk at the Medical Research Council Developmental Psychology Unit in London in the late 60s/early 70s (exact date unknown).

In 1983 Chuck Hull invented the first 3D printer. It could produce small plastic objects directly from a digital file on a computer. Instead of using ink the printer used plastic - adding layer upon layer to create an object. At first no-one was interested but now 3D printing technology is used widely, both by amateur hobbyists and industry. It's been taken up enthusiastically in the medical world to help separate conjoined twins and the next step is to help create human tissue for regenerative medicine.

A unique way of life came to an end in Hong Kong in 1993 when Kowloon Walled City was demolished. When the rest of Hong Kong was a British colony, the seven acres of the Walled City were still nominally under the control of mainland China – but it became a lawless world of its own, a haven for gang crime and illegal dentistry. At one point it was one of the most of the most densely populated places the world has ever seen.Lucy Burns speaks to Albert Ng, who grew up in Kowloon Walled City, and urban designer Suenn Ho, who studied it before its demolition.PICTURE: Kowloon Walled City in January 1987 (Photo by South China Morning Post staff photographer via Getty Images)

After four white policemen were acquitted of killing a black man - Miami rioted. Citizens took to the streets on the night of May 17th 1980. The unrest lasted for three days. 18 people died, hundreds were injured, and hundreds of millions of dollars worth of damage were done to property. Sheila Cook has been hearing from Lonnie Lawrence who was a childhood friend of the dead man, but also a spokesman for the police force involved.Photo: A Florida National Guardsman directs traffic away from the northwest section of Miami as fires burn out of control and looting continues.

The story of a scientist who helped solve a Cold War mystery involving flatulent fish and Soviet submarines. During the Cold War, foreign submarines infiltrated neutral Sweden's territorial waters. In response, the Swedish navy built up a secret database of tell-tale signs to detect the presence of lurking subs and conducted high profile submarine hunts. But the country's submarine scare continued even after the end of the Cold War. So in 1995, the Swedish government launched an investigation. Alex Last spoke to Swedish biologist, Dr Håkan Westerberg, who discovered that one of Sweden's key indicators for submarines, was not what it seemed. Photo: Herring shoal (Science Photo Library)

Over a period of four years before his death in December 2004, Prince Bernhard of the Netherlands, the consort and husband of former Queen Juliana, gave a series of secret interviews to two Dutch journalists, on condition that nothing was published until after his funeral. In his conversations with the reporters, the German-born Prince sought to justify a string of extra-marital affairs and a million dollar bribe he had received in the 1970s from the American aircraft manufacturer Lockheed. Prince Bernhard also revealed for the first time the existence of an illegitimate daughter born as a result of an affair in the United States. The publication of the Prince's confessions by De Volkskrantran newspaper shocked the Dutch public, but were met with silence by the Palace. Mike Lanchin spoke to Jan Tromp, one of the journalists who spent hours interviewing the controversial Dutch royalty.

After decades of campaigning in Japan, the pill was finally legalised in 1999. In contrast the male impotency drug Viagra was approved for use in just six months, and legalised before the contraceptive pill for women. Politician Yoriko Madoka pushed hard for the right to take the pill and told Rebecca Kesby that sexism and male dominance in Parliament is why it took so long.(Photo: A collection of contraceptive pills.
