After
World War II, estates of the princely (
Choceň) branch of the family were confiscated under the
Decree of the President of Republic, as the late Prince
Ulrich (1893–1938) was reproached for his declared
German nationality and active collaboration with the
Sudeten German Party. Estates of the other branches,
Kostelec and
Chlumec, which had been confiscated by the Nazis during the
German occupation, were returned after 1945 but confiscated again, this time by the ruling
Communist Party in 1948. After the
Velvet Revolution and the fall of Communism, several possessions – for example,
Karlova Koruna Chateau and
Kost Castle – were returned to the family. From 2003, the senior member of the princely branch, Prince Ulrich's son
Franz Ulrich, sued the
Czech Republic for return of the properties confiscated in 1945 only because, he maintained, the confiscation implicitly labeled his family as historical traitors against Czechoslovakia and as willful
collaborators during the Nazi occupation. The Kinsky family has denied such charges, arguing that Prince Franz Ulrich was just two years old at the time of his father's death and that he and his mother, Princess Kinsky (
née Baroness Mathilde von dem Bussche-Haddenhausen — whose family reputedly plotted against
Hitler), had left the occupied country and went into exile in
Argentina shortly afterwards. According to a 2005 judgement by the
Constitutional Court of the Czech Republic, at least the expropriations enacted before the
Communist coup d'état (1948) are valid. Prince Franz Ulrich died in 2009 in
Buenos Aires after a brief illness and was survived by his widow,
née Countess Lena Hutten-Czapska. He left as heir to his title, properties and pending claims against the Czech state, his son Karl ("Charlie") and three grandchildren. ==Notable members==
