Witness History
Apr 4, 2024

In the 1990s, Bluetooth was invented in a lab in Lund, Sweden.

The technology is used today to wirelessly connect accessories such as mice, keyboards, speakers and headphones to desktops, laptops and mobile phones.

It’s named after Harald Bluetooth, a Viking king who was said to have blue teeth.

Sven Mattisson, one of the brains behind the technology, tells Gill Kearsley how the name Bluetooth came about following some drinks after a conference.

The Spanish king reclaims his throne

In 1975, the death of General Francisco Franco was announced in Spain, bringing to an end 36 years of dictatorship.

Franco had already chosen his successor: Prince Juan Carlos, grandson of the last monarch, Alphonso XIII. This was the man who - Franco thought - would continue his authoritarian, anti-democratic and deeply conservative regime.

But Juan Carlos defied expectations. In the years that followed, he would lead Spain from a dictatorship to a democracy until, in 1977, the country held its first free elections for 41 years.

Jane Wilkinson tells the story using excerpts from the 1981 BBC and TVE documentary, Juan Carlos: King of Spain. This episode was made in collaboration with BBC Archives.

The death of Franco

General Francisco Franco died in November 1975, ending 36 years of dictatorship over Spain.

The general had been in power since 1939 after winning the country’s bloody civil war, and his death followed a long illness.

He was mourned by conservative Spaniards but those on the left celebrated, calling him a fascist who had once been an ally of Hitler and Mussolini.

In 2015, Louise Hidalgo spoke to Jose Antonio Martinez Soler, a young journalist about the ending of an era.

Angela Merkel suspends EU asylum rules in 2015

In the summer of 2015, there was a surge in the number of people from Syria, Afghanistan and Iraq, seeking asylum in Europe.

Social Democrat politician Aydan Özoğuz was Angela Merkel's minister of state concerned with immigration, refugees and integration from 2013 to 2018. She describes to Josephine McDermott visiting her father's home city of Kilis in Turkey, near the Syrian border in 2015, where refugees were being sheltered.

And she recalls the motivation for Mrs Merkel's decision to suspend the EU's Dublin Regulation, which temporarily allowed free passage for Syrian asylum seekers, but drew opposition from critics.
