The sacred song of war

It was Peter the Great who created a new capital on the Baltic, and Catherine the Great who extended Russian influence south and west. Sweden, Poland, and the Ottomans all felt the Russian expansion in a century of geopolitical drama. This, says presenter Misha Glenny, is all part of the build up to today's war in Ukraine. With contributions from Virginia Rounding, biographer of Catherine the Great; Prof Simon Dixon of University College London; Prof Robert Service, author of The Last Tsar; Prof Janet Hartley, author books on the Volga and Siberia; and Dr Sarah Young of the UCL School of Slavonic and East European Studies.

Catherine the Great and the question of Europe

Russia's massive empire was not like that of Britain or France. It expanded across the land, making it more like the United States of America. And from very small beginnings, it became the biggest contiguous landmass in the world.  Presenter Misha Glenny speaks to James Hill of the New York Times about travelling to the edges, and also to Janet Hartley, author of Siberia: A History of the People. Plus further contributions from Ukrainian academic Olesya Khromeychuk, Anna Reid, the author of Borderland and Leningrad, and the Tblisi-based journalist, Natalia Antelava, editor-in-chief at Coda Story.

The Invention of Russia: The empire strikes back

Countries look so cohesive on the map - sturdy borders, familiar shapes. Don't be misled. They didn't always look like this. This is the story of Russia, biggest contiguous country on the planet, told from the time when it was still very small.  With contributions across the series from Janet Hartley, author of a history of the Volga; Rhodric Braithwaite, former ambassador to Moscow; historian and sociologist, Mischa Gabowitsch; Anthony Beevor; Natalia Antelava; Kateryna Khinkulova; Dominic Lieven; Olesya Khromeychuk; and James Hill of the New York Times.

The invention of Russia: A tale of two Ivans

Tel Aviv is a bustling place and for a blind person it can be a little daunting, as BBC journalist, Peter White, discovers. The narrow streets in the older parts of town are full of open air cafes, buskers and people visiting the markets and local shops. It is a lively place and Peter's first challenge comes when he tries to navigate the local busses, only to find that without being able to see them approaching, it is virtually impossible to get them to stop! Today signs of expansion are evident in the building works going on everywhere and Peter hears from young people concerned about political, social and environmental pressures. The city is home to some exciting activities, including tandem bike riding, with a local club attracting 70 plus blind and partially sighted members. As he walks around he becomes aware of some of the steps being taken to make things more accessible, including the addition of sound systems on public crossings that at least offer protection from the constant and sometimes fast flowing traffic.  In the local parks Peter hears from people about other fun activities offered locally, from outdoor gyms through to long meals taken with friends and family. Younger people he meets share their hopes and dreams and explain what it has been like growing up with a disability in Tel Aviv. (Photo: Peter White and his guide walk along the streets of Tel Aviv)
