Taiwan Garrison Command
The Taiwan Garrison Command (臺灣警備總司令部; Táiwān Jǐngbèi Zǒng Sīlìngbù) was a Republic of China military organization established in August 1945 as the Taiwan Garrison General Headquarters to oversee the retrocession of Taiwan from Japanese control, including repatriation of Japanese nationals and assumption of administrative authority.[1] Reorganized in September 1949 into the Taiwan Provincial Garrison General Headquarters following the Kuomintang government's retreat to the island, it became the primary agency for internal security, public order, and counter-subversion efforts.[1] The command enforced martial law, declared effective May 20, 1949, through surveillance, arrests, and suppression of activities deemed threats to national security, such as communist infiltration or pro-independence movements, operating as a de facto secret police under military oversight until martial law's lifting in 1987.[2][3] Abolished in August 1992 amid Taiwan's transition to democracy, its legacy encompasses both the maintenance of regime stability against existential communist pressures and extensive political repression during the White Terror era, including the political imprisonment of over 140,000 individuals.[1][2]
