The Nanjing decade (also Nanking decade, Chinese: 南京十年 Nánjīng shí nián, or The Golden decade, Chinese: 黃金十年 Huángjīn shí nián) is an informal name for the decade from 1927 (or 1928) to 1937 in the Republic of China. It began when Nationalist Generalissimo Chiang Kai-shek took Nanjing from Zhili clique warlord Sun Chuanfang halfway through the Northern Expedition in 1927. Chiang declared it to be the national capital despite the left-wing Nationalist government in Wuhan. The Wuhan faction gave in and the Northern Expedition continued until the Beiyang government in Beijing was defeated in 1928. The decade ended with the outbreak of the Second Sino-Japanese War in 1937 and the retreat of the national government to Wuhan.
Nanjing was of symbolic and strategic importance. The Ming dynasty had made Nanjing a capital, the republic had been established there in 1912, and Sun Yat-sen's provisional government had been there. Sun's body was brought and placed in a grand mausoleum to cement Chiang's legitimacy. Chiang was born in the neighboring province and the general area had strong popular support for him.
The Nanjing decade was marked by both progress and frustration. The period was far more stable than the preceding warlord era. There was enough stability to allow economic growth and the start of ambitious government projects, some of which were taken up again by the new government of the People's Republic after 1949. Nationalist foreign service officers negotiated diplomatic recognition from western governments and began to unravel the unequal treaties. Entrepreneurs, educators, lawyers, doctors, and other professionals were more free to create modern institutions than at any earlier time. Yet there was also government suppression of dissent, corruption and nepotism, revolt of several provinces, conflict within the government, the survival and growth of the Chinese Communist Party, and widespread protest against the government's failure to stop Japanese aggression.
