On 1 September 1945, the Jakarta branch of the
People's Security Agency (
Badan Keamanan Rakyat/BKR) was founded with Lt. Col. Mufraeni Mukmin as its branch leader. On 29 September 1945, allied forces (with
Netherlands Indies Civil Administration personnel attached) under the command of
Lt. Gen. Sir
Philip Christison landed from in
Tanjung Priok Harbor to disarm
Japanese troops and to liberate
prisoners of war. BKR and Indonesian youth in API, Kris Hisbulah, and other
paramilitary organizations confronted the allied forces. To increase armed resistance against the
Allied forces, the government of the
Republic of Indonesia founded the People's Security Armed Forces (
Tentara Keamanan Rakyat/TKR) on 5 October 1945. One infantry regiment of TKR in
Jakarta was organized under the command of Lt. Col. Mufraini Mukmin. On 24 December 1949, there began a transfer of power from the
Dutch government to the Republic of Indonesia. With that transfer came a signing of documents to shift the
Jakarta Raya region from Dutch-based Batavia En Ommelanden to
Indonesia-based Jakarta Raya, under the supervision of the UN Security Council's Three Nations Commission, "Komisi Tiga Negara" (KTN). In December 1949, some units such as "Kala Hitam" Battalion and "Siluman" Battalion were dispatched to reinforce Basis Commando Jakarta Raya, following which Lt. Col. R. Taswin Natadiningrat was appointed as commander of Basis Commando Jakarta Raya. In January 1950, Basis Commando Jakarta Raya changed its name to Greater Jakarta Military Base Command (Komando Militer Pangkalan Jakarta Raya or KMP Jakarta Raya). Then, following instructions from the Army
HQ on 10 May 1950, City Military Command (Komando Militer Kota or KMK) was changed to Greater Jakarta City Military Command (Komando Militer Kota Besar Jakarta Raya or KMKB-DR). As the
Republic of Indonesia continued to develop, the Army Chief of Staff released two letters of command numbered SP 1671/10/1959 and SP 1672/10/1959 (both dated 24 December 1959), which reorganized the Army command for the capital, thus the
5th Military Regional Command/Jayakarta (
Komando Daerah Militer V/Jayakarta, also known as the Jakarta Military Region, MRC 5/Jaya, Kodam V/Jaya or Region V/Jayakarta) was founded in the basis of the KMKB-DR which a new commander was to be named for this separate command for the region. After that, on 19 January 1960, at 9:00 am in
Lapangan Banteng, the Chief of Staff of the Army, Lt. Gen. Abdul Haris Nasution, appointed Col.(inf)
Umar Wirahadikusumah as the first Commander of Kodam V/Jaya. The 1st Mechanized Infantry Brigade (formerly known as the 1st Infantry Brigade) took part in the events of the
30 September Movement, its commander being one of the attempted coup's leaders. Col. Wirahadikusumah was spared from any action due to pressure from Maj. Gen.
Suharto, then-commander of
Kostrad, for him to prevent having to join the rebel forces in his area of operations. In 1984, the command simply became Kodam Jaya as part of an
armed forces-wide reorganization, its numerical designation removed. The name "Jayakarta" comes from the original name of the city of
Jakarta before the arrival of the
Dutch and is rooted in the historic name of Jakarta, coming from
Sanskrit: "Jaya" (“victorious”) and "Karta" (“achieved”), literally “achieved through victory”, translated as "Complete Victory" or "Great Deed". It refers to the historical background of the historical city when the Army of
Fatahillah successfully defeated the
Sunda Kingdom and drove the
Portuguese forces out of Jakarta, then known as
Sunda Kelapa, in the 16th century. ==Territorial units==
