Max Pearson presents a collection of the week's Witness History interviews from the BBC World Service. Our guest is Mercedes Peñalba- Sotorrío, a senior lecturer in modern European history at Manchester Metropolitan University, England.

We start with the death of General Francisco Franco in 1975 ending 36 years of dictatorship over Spain.

Then, we use archive to hear how King Juan Carlos reclaimed the Spanish throne in 1975 and led the country to a democracy. This episode was made in collaboration with BBC Archives.

We hear from a Social Democrat politician about Chancellor Angela Merkel's decision to suspend asylum rules for Syrians fleeing war in 2015.

How the Bosnian war ended with the Dayton Peace Accords in 1995.

Next, how a substitute fielder ran out the Australian captain in the fourth test of the 2005 Ashes, turning the game in England's favour.

Finally, we use archive to hear about cold war diplomacy in the Geneva summit in 1985.
