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.
