The Indonesian government claimed this territory as well, on the basis that it had belonged to the Dutch East Indies and that the new Republic of Indonesia was the legitimate successor to the former Dutch colony.
The military history of Indonesia includes the military history of the modern nation of Republic of Indonesia, as well as the military history of the states which preceded and formed it. It encompassed a kaleidoscope of conflicts spanning over a millennia. The ancient and medieval part of it began as tribal warfare began among indigenous populations, and escalated as kingdoms emerged. The modern part is defined by foreign colonial occupations, battles for independence through guerrilla warfare during Indonesian National Revolution, regional conquests and disputes with neighbouring countries, as well as battles between the Republic and separatist factions. Since the formation of the Republic, the military has played significant role in state affairs. However, in Post-Suharto era, the Indonesian military has retreated from politics, yet it still possesses some influences.
