Fernand Braudel
Since his incarceration, Öcalan has significantly changed his ideology through exposure to Western social theorists such as Murray Bookchin, Immanuel Wallerstein, Fernand Braudel, and Friedrich Nietzsche (who Öcalan calls "a prophet"). Abandoning his old Marxism-Leninist and Stalinist beliefs, Öcalan fashioned his ideal society called democratic confederalism, heavily inspired on Bookchin's libertarian socialist idea of communalism.
