There was a large squatting movement in the newly formed state of Austria following the First World War. Famine was a significant problem for many people in Austria and the "Siedler" (settler) movement developed as these people tried to create shelter and a source of food for themselves. The Ernst Kirchweger Haus (EKH) in Vienna was squatted as a social centre in 1990 and legalised in 2008. In 2014, 1,500 riot police officers, a tank-like police vehicle, a police water cannon and helicopters were used to clear a building occupied by the group Pizzeria Anarchia in Vienna.
