In 1916, Zurich was a beacon for refugees. Fleeing the death and destruction of World War I, artists and free-thinkers from all over Europe fled to the neutral Swiss city.

And it was here that the people who would start the art movement Dada came together. In a rare interview from 1959, held in the BBC archive, Richard Huelsenbeck describes how the group of young artists and pacifists shared a despair about the war and a disgust for bourgeois values.

At the Cabaret Voltaire, he and the Romanian French-born poet Tristan Tzara, the French sculptor Jean Arp and Romanian-Israeli artist Marcel Janco experimented. Performances were known for their spontaneity, chance and absurdity - a departure from the conventional which confronted audiences. It was the beginning of an aesthetic which would spread across Europe and to New York City, eventually influencing Surrealism and later punk. This episode is produced and presented by Josephine McDermott.

On 9 July 2011, a new flag was raised in the city of Juba as South Sudan became the world's newest nation.

It followed a peace deal that ended a long and bloody civil war in Sudan, which had killed more than two million people.

Six months earlier, a referendum in the south of Sudan saw more than 99% of nearly four million voters choose independence.

Malual Bol Kiir was 17 at the time and had been displaced during the conflict. He tells Daniel Rosney how he was overwhelmed with hope and optimism as change finally came.

On the afternoon of 10 July 1976, there was an explosion at the ICMESA chemical factory near Seveso, in northern Italy.

A cloud containing a poisonous gas called dioxin spread over the town.

For days, residents didn't realise they were in danger.

They later developed skin conditions like chloracne and thousands of animals died or had to be slaughtered.

Rachel Naylor speaks to Giuseppe Cassina, former Mayor of Seveso.

In the 1970s, thousands of immigrant workers living in "foyers" or workers' hostels across France stopped paying rent.

They were protesting against rent hikes and living conditions in the foyers, known for their tiny box rooms and substandard conditions, and against the racism of the housing management companies.

The strike mainly took place in foyers run by Sonacotra, formerly Sonacotral: the National company for the construction of housing for Algerian workers.

The strike lasted some five years, from around 1975 to 1980. Estimates vary, but at least 20,000 residents are thought to have taken part at the peak of the strike.

Today, the strike is still remembered as a founding moment in the struggle for immigrants' rights in France.

Mohammed Kherbachi, originally from Algeria, tells Carolyn Lamboley why he took part in the strike. A Whistledown production.
