Otto von Bismarck

Born a Junker landowner in 1815, Otto von Bismarck climbed through Prussian diplomacy - ambassador to Russia and France, both houses of parliament - before Wilhelm I made him minister president in 1862. Over eight years he engineered three short wars against Denmark, Austria, and France, each one deliberate, each one won. Austria's defeat in 1866 let him form the North German Confederation; France's collapse in 1870 cleared the path to German unification under Prussian rule in 1871, with Bismarck as its first chancellor. He built the first welfare state to undercut his socialist enemies, waged the Kulturkampf against the Catholic Church until it backfired, then pivoted to ally with the Centre Party he'd just fought. For nearly twenty years he kept Europe stable through balance-of-power diplomacy while ruling autocratically at home, sidelining the Reichstag and concentrating power in Junker hands. Wilhelm II dismissed him in 1890; he spent his last years writing memoirs, dying in 1898 with monuments already rising and historians already arguing whether he was a visionary or a tyrant.
