The 1st Group Army was created by 1988 when the PLA's infantry corps were reorganized into group armies. The unit(s) forming the 1st Group Army were descended from the
First Field Army of the late
Chinese Civil War. 1st Group Army was subordinated to the
Nanjing Military Region, which had strong political ties to
paramount leader Deng Xiaoping. During the
1989 Tiananmen Square protests and massacre, the formation remained in place near
Shanghai as a safeguard against unrest. During the force reductions of the late-1990s, the group army's 2nd Division was transferred to the
People's Armed Police as Unit 8690. From the mid-2010s, the group army transferred to the
Eastern Theater Command, which replaced the military region. In April 2017, the group army was designated as the 72nd Group Army. ==Organization==
