Johanna "Hannah" Arendt (; German: [ˈaːʀənt]; 14 October 1906 – 4 December 1975) was a German-born American political theorist. Her eighteen books and numerous articles, on topics ranging from totalitarianism to epistemology, had a lasting influence on political theory. Arendt is widely considered one of the most important political philosophers of the twentieth century.As a Jew, Arendt chose to leave Nazi Germany in 1933, and lived in Czechoslovakia, Switzerland, and France before escaping to the United States in 1941 via Portugal. She became an American citizen in 1950, having been stripped of her German citizenship in 1937. Her works deal with the nature of power and the subjects of politics, direct democracy, authority, and totalitarianism. The Hannah Arendt Prize is named in her honor.
