Liechtenstein - one of the oldest Moravian and Czech manor and princely families. Their beginnings are found in the 11th century in Bavaria. They came to Moravia through the future King Přemysl Otakar and became one of the richest Moravian families. They left behind many monuments: Lednice-Valtice area, castles in Mikulov, Valtice, Velké Losiny or Prague. The Principality of Liechtenstein became one of the richest countries in the world. During the Second World War it helped people persecuted by Nazism, yet the property of his citizens in Czechoslovakia in 1945 was confiscated. Diplomatic relations of the Czech Republic with Liechtensteins were not restored until 2009.
