中国が統一されたのはいつですか？
After Sun's death in March 1925, Chiang Kai-shek became the leader of the KMT. In 1926, Chiang led the Northern Expedition through China with the intention of defeating the Beiyang warlords and unifying the country. Chiang received the help of the Soviet Union and the Chinese Communists; however, he soon dismissed his Soviet advisers. He was convinced, not without reason, that they wanted to get rid of the KMT (also known as the Chinese Nationalists) and take over control. Chiang decided to strike first and purged the Communists, killing thousands of them. At the same time, other violent conflicts were taking place in China; in the South, where the Communists had superior numbers, Nationalist supporters were being massacred. These events eventually led to the Chinese Civil War between the Nationalists and Communists. Chiang Kai-shek pushed the Communists into the interior as he sought to destroy them, and established a government with Nanking as its capital in 1927. By 1928, Chiang's army overturned the Beiyang government and unified the entire nation, at least nominally, beginning the so-called Nanjing Decade.
