Hans Kelsen (; German: [ˈhans ˈkɛlsən]; October 11, 1881 – April 19, 1973) was an Austrian jurist, legal philosopher and political philosopher. He was the principal architect of the 1920 Austrian Constitution, which with amendments is still in operation. Due to the rise of totalitarianism in Austria (and a 1929 constitutional change), Kelsen left for Germany in 1930 but was forced out of his university post after the Nazi seizure of power in 1933 because of his Jewish ancestry.
