Zunyi Conference
Of the three leaders who had controlled the Party before the Zunyi Conference, only Zhou Enlai's political career survived. Zhou was held partially responsible for the Red Army's defeat, but was retained at the top level of Party leadership because of his differences with Bo and Braun at Ningdu, his successful tactics in defeating Chiang's fourth Encirclement Campaign, and his resolute support of Mao. Although the failed leadership of Bo Gu and Otto Braun was denounced, Mao was not able to win the support of a sufficient number of Party leaders to gain outright power at the conference.
