The Republic of China Army takes its roots in the National Revolutionary Army, which was established by Sun Yat-sen in 1925 in Guangdong with a goal of reunifying China under the Kuomintang. When the People's Liberation Army won the Chinese Civil War, much of the National Revolutionary Army retreated to Taiwan along with the government. It was later reformed into the Republic of China Army. Units which surrendered and remained in mainland China were either disbanded or incorporated into the People's Liberation Army.
