Although Sun is considered to be one of the greatest leaders of modern China, his political life was one of constant struggle and frequent exile. After the success of the revolution and the Han Chinese regaining power after 268 years of living under Manchurian rule (Qing dynasty), he quickly resigned from his post as President of the newly founded Republic of China to Yuan Shikai, and led successive revolutionary governments as a challenge to the warlords who controlled much of the nation. Sun did not live to see his party consolidate its power over the country during the Northern Expedition. His party, which formed a fragile alliance with the Chinese Communist Party, split into two factions after his death.
Sun was born as Sun Wen (Cantonese: Syūn Màhn; 孫文), and his genealogical name was Sun Deming (Syūn Dāk-mìhng; 孫德明). As a child, his pet name was Tai Tseung (Dai-jeuhng; 帝象). Sun's courtesy name was Zaizhi (Jai-jī; 載之), and his baptized name was Rixin (Yaht-sān; 日新). While at school in Hong Kong he got the art name Yat-sen (Chinese: 逸仙; pinyin: Yìxiān).Sūn Zhōngshān (孫中山), the most popular of his Chinese names, is derived from his Japanese nameNakayama Shō (中山樵), the pseudonym given to him by Tōten Miyazaki while in hiding in Japan.
