Zhang Xueliang

In 1928, Zhang, at the time a general in the Northeastern Army, became the commander of the army and leader of the Fengtian clique upon his father's assassination. A reformer sympathetic to nationalist ideas, he completed the official reunification of China by pledging loyalty to the Nationalist government, and used his powerful base to wield significant influence in the politics of the Nanjing decade. Zhang followed Chiang's policy of nonresistance to the Japanese invasions of Manchuria in 1931 and Rehe in 1933, after which he was forced to resign as head of the Northeastern Army. In 1935, Zhang was again appointed its commander to suppress the Communists, but became disillusioned with Chiang's policy of "stabilizing China before resisting Japan", and helped to plan the Xi'an Incident. Following the incident, Chiang had Zhang arrested for insubordination and sentenced to house arrest, first in mainland China and then in Taiwan. Zhang would remain under confinement until 1988, a period of more than 50 years. He died of pneumonia in 2001, at the age of 100. Provided by Wikipedia
