Walter Ulbricht

Ulbricht became General Secretary of the Socialist Unity Party of Germany (SED), effectively becoming the leader of East Germany. He oversaw the Stalinization of the country and the establishment of a one-party state.

A workers' uprising in East Berlin and other cities was violently suppressed by Soviet troops. Ulbricht's government had raised work quotas, sparking the protests. The uprising was a major challenge to his rule and led to a temporary relaxation of policies.

Ulbricht was the primary architect of the Berlin Wall, which was built to stop the mass exodus of East Germans to the West. The wall physically divided the city and became a central symbol of the Cold War.

Ulbricht introduced economic reforms that decentralized decision-making and gave more autonomy to enterprises. The reforms aimed to improve efficiency and productivity but were later reversed by his successor, Honecker.
