Through the Trianon Peace Treaty (signed in 1920) Hungary lost two thirds of its territories around 100 years ago. Every third Hungarian suddenly lived abroad. In total there are 1.8 million Hungarians who live in other countries such as Slovakia, Ukraine or Romania. Families were torn apart, the economy collapsed. The large Kingdom of Hungary - part of the powerful Habsburg dual monarchy - became a small country. In the summer of 2020, the Hungarian head of government inaugurated a controversial monument: the monument to national unity. The walls are engraved with the names of more than 12,500 places that once belonged to Hungary before the borders in Europe were redrawn by the victorious powers after World War I. Victor Orbán has been courting foreign Hungarians with one-two passports and voting rights for years. The neighboring countries are alarmed. This leads to tensions and conflicts in Europe. Outrage, anger and sadness. The feelings of Hungarians at that time are still alive today and it is not only nationalists and right-wing radicals who try to make political capital out of them. The documentary examines the question: How is it possible that an event that took place one hundred years ago can have such far-reaching consequences and still be politically relevant today?
