The intersection of politics and philosophy inspired other philosophers in Weimar Germany, when radical politics included many thinkers and activists across the political spectrum. During his 20s, Herbert Marcuse was a student in Freiburg, where he went to study under Martin Heidegger, one of Germany's most prominent philosophers. Marcuse himself later became a driving force in the New Left in the United States. Ernst Bloch, Max Horkheimer and Walter Benjamin all wrote about Marxism and politics in addition to other philosophical topics. From the perspective of Jewish philosophers in Germany, they also considered the problems posed by the "Jewish question". Political philosophers Leo Strauss and Hannah Arendt received their university education during the Weimar Republic and moved in Jewish intellectual circles in Berlin, and were associated with Norbert Elias, Leo Löwenthal, Karl Löwith, Julius Guttmann, Hans-Georg Gadamer, Franz Rosenzweig, Gershom Scholem, and Alexander Altmann. Strauss and Arendt, along with Marcuse and Benjamin, were among the Jewish intellectuals who managed to flee the Nazi regime, eventually emigrating to the United States. Carl Schmitt, a legal and political scholar, was also a vocal fascist supporter of both the Nazi regime and Spain's Franco; however, he published works of political philosophy that remained studied by philosophers and political scholars with radically different views, such as Alain Badiou, Slavoj Žižek, and his contemporaries Hannah Arendt, Walter Benjamin, and Leo Strauss.
