In 1919, the victors of the First World War gathered in Paris and set out to redraw the map of the world. They believed they were building a lasting peace. What they actually built was a powder keg. The borders they drew, the promises they broke, and the nations they ignored set in motion a chain of events that never truly ended. Eastern Europe was consumed by wars, revolutions, and ethnic violence long after the armistice was signed, and the wounds have never fully healed. The conflicts tearing Ukraine apart today, the battle over memory and identity, the question of who owns the land and who belongs to the nation, trace directly back to decisions made over a century ago.
