Flags of Indonesia

Republic of Indonesia (sovereignty recognized)

Who & why: after four years of guerrilla warfare and international diplomatic pressure following the 1945 proclamation, the Netherlands formally transfers sovereignty at the Hague Round Table Conference on 27 December 1949. Indonesia goes on to absorb Dutch New Guinea in 1963 and East Timor in 1975–76 (the latter relinquished in 1999–2002), and transitions from Suharto's three-decade authoritarian "New Order" to multiparty democracy after his 1998 resignation.

What it represents: the red-over-white flag proclaimed on 17 August 1945, hoisted again on 27 December 1949 when the Dutch formally transferred sovereignty, and made official on 17 August 1950; Law No. 24 of 2009 sets the flag's protocol and prohibited acts, and gives its colours as RGB 255,0,0 and 255,255,255.

Proclaimed Republic of Indonesia (National Revolution)

Who & why: Sukarno and Mohammad Hatta proclaim independence on 17 August 1945, two days after Japan's surrender, before the Dutch can reoccupy the archipelago. The Netherlands refuses to accept the proclamation and launches two large "police actions" (1947, 1948–49) to reassert colonial control; the republic survives through guerrilla resistance and mounting international pressure, particularly from the United States and the United Nations, until the Dutch relent.

What it represents: the red-white flag was introduced and hoisted at the Proclamation of Independence in Jakarta on 17 August 1945, the Bendera Pusaka sewn by Fatmawati. Its colours are linked to the Majapahit banner; Wikipedia says students and nationalists revived red and white in the 1920s and that it was first flown in Java in 1928 and quickly banned under Dutch rule, while FOTW says a red-over-white banteng flag was adopted by students in Leiden in 1922, flown by the Partai Nasional Indonesia in 1928, and the plain red and white first raised at a student congress in Batavia in 1929.

Japanese military occupation

Who & why: Japanese forces overrun the Dutch East Indies in early 1942, ending Dutch rule within months and interning Dutch civilians and soldiers. Japan initially courts Indonesian nationalists, permitting limited use of the red-white flag and the Indonesian language late in the occupation as the war turns, and it is Japan's own August 1945 surrender that creates the opening Sukarno and Hatta use to proclaim independence.

What it represents: Wikipedia dates the Imperial Japanese flag's use to 8 March 1942 - 17 August 1945 and Flags of the World notes the red-over-white flag was hoisted at the proclamation of 17 August 1945. The sources read do not describe a naval or military ensign for the occupation, and do not say whether an Indonesian flag was permitted or banned.

Dutch East Indies

Who & why: the bankrupt Dutch East India Company (VOC) is dissolved on 31 December 1799 and its territories nationalized as a formal Dutch colony on 1 January 1800. The colonial state expands over the nineteenth century into direct control of nearly the entire archipelago, run under the exploitative "Cultivation System" from the 1830s and later a nominally more liberal "Ethical Policy," while a broad nationalist movement builds through the early twentieth century.

What it represents: Wikipedia says the Dutch flag was used in the Dutch East Indies from 1 January 1800 to 27 December 1949, and that the red-white flag first flown in Java in 1928 was quickly prohibited under Dutch rule. The sources read do not say whether the colonial state had a distinct ensign, and the page's 1942 end date is not taken from them.

Dutch East India Company (VOC) rule

Who & why: the Dutch East India Company, chartered in 1602 with quasi-sovereign powers to wage war and administer territory, gradually displaces Portuguese traders and local sultanates from the spice trade, establishing Batavia (modern Jakarta) in 1619 as its administrative and military headquarters. Company rule is commercial rather than fully territorial at first, tightening its grip archipelago by archipelago over two centuries before collapsing under debt and mismanagement in 1799.

What it represents: the Dutch tricolor bearing the Company's own interlocking VOC monogram, flown over trading posts and forts rather than a unified colony. Wikipedia dates the Company flag to 20 March 1602 - 1 January 1800 (a navigation box says 1603); the sources read do not describe the monogram.

Fragmented sultanates (post-Majapahit)

Who & why: Majapahit's authority collapses in the early sixteenth century as Islam spreads through the archipelago via trade networks, and power fragments among rival coastal sultanates — Demak, later Mataram, on Java; Aceh in northern Sumatra; Banten in the west — none of which reunifies the whole archipelago before Dutch traders arrive.

What it represents: no single flag can honestly represent this genuinely fragmented span; each sultanate kept its own banners and none achieved archipelago-wide reach, so this entry is shown deliberately blank rather than inventing a false unifying symbol.

Majapahit Empire

Who & why: founded in 1293 by Raden Wijaya on the ruins of a failed Mongol invasion, Majapahit becomes the most powerful pre-colonial state in Indonesian history, claiming influence over much of the archipelago and parts of the wider Malay world at its height under Hayam Wuruk and his minister Gajah Mada in the mid-1300s. Its later fifteenth- and early sixteenth-century decline, hastened by succession conflicts and the rise of Islamic coastal trading states, opens the door to the fragmented sultanate era that follows.

What it represents: Wikipedia links the flag's colours to the Majapahit Empire's banner, listing 11 November 1293 in its infobox, and FOTW says the Indonesian flag is based on a Majapahit flag with nine red and white stripes, now used as a jack. The name Gula Kelapa and the Javanese chronicles that the page cited are not in either source.

Srivijaya

Who & why: centered on Sumatra near modern Palembang, Srivijaya rises in the mid-600s as a Buddhist maritime and trading empire, controlling the Strait of Malacca and much of the surrounding archipelago's sea trade for over six centuries. Its influence fades from the eleventh century under pressure from South Indian Chola raids and rising regional rivals, and its remaining territory is absorbed into the ascendant Majapahit sphere by the late 1200s.

What it represents: no securely documented flag or banner survives from Srivijaya; its power was expressed through temple inscriptions, tribute relationships, and naval control of trade routes rather than a fixed territorial symbol. Shown here honestly blank rather than invented.

Kutai & Tarumanagara (Early Hindu Kingdoms)

Who & why: the archipelago's earliest kingdoms to leave their own written record are Kutai, on the Mahakam River in East Kalimantan, and Tarumanagara, in West Java, both taking shape as Indian Hindu-Buddhist religious and political culture spreads through maritime trade networks rather than conquest. Kutai's ruler Mulawarman is named on Yupa inscriptions dated to roughly 400 CE, commemorating gifts to Brahmin priests; Tarumanagara's King Purnawarman is separately attested a few decades later on inscriptions including the Ciaruteun stone near Bogor. Neither kingdom is politically connected to the other or to Srivijaya, which rises on Sumatra by the mid-600s as the archipelago's first genuinely dominant maritime power.

What it represents: no flag or comparable state banner is attested for either kingdom; their authority is recorded through stone inscriptions and ritual endowments, not vexillology. Shown here honestly blank rather than invented.

World context: Kutai's c. 400 CE inscriptions fall within the twilight years of India's own Gupta Empire, the classical civilization whose Sanskrit learning and Hindu religious culture this same maritime diffusion carries eastward across the Bay of Bengal; in the wider world, the same decades see the Western Roman Empire's final crisis (Rome itself sacked by the Visigoths in 410, the last western emperor deposed in 476) and the early rise of the Mekong-delta kingdom of Funan, another Indianized Southeast Asian state whose own trade networks overlapped with Tarumanagara's.
