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.
as an archipelagic nation, historically indonesia has always been a maritime power since srivijaya and majapahit era. the 7th century srivijayan empire for example, thrived by maximizing the potential of the sea. during its early formation until the suharto's new order era, indonesian military was heavily focused on its land component. however, by the 21st century, its interest has shifted to maritime sphere, as in 2014 president joko widodo has expressed a desire to turn indonesia into a "maritime axis".
