Early Peoples and the Hindu-Buddhist Kingdoms: Srivijaya and Majapahit
Indianised maritime kingdoms rose across Sumatra and Java, from the Buddhist trading thalassocracy of Srivijaya to the imperial reach of Majapahit, leaving monuments such as Borobudur and Prambanan.
Long settled by Austronesian peoples, the western archipelago was drawn from the early first millennium CE into the trade and culture of the Indian Ocean. Indian religious and political ideas blended with local traditions to produce a succession of 'Indianised' Hindu and Buddhist kingdoms whose wealth rested on the monsoon trade in spices, gold and forest products passing through the straits between the Indian Ocean and the South China Sea.
From around the seventh century the Buddhist kingdom of Srivijaya, based at Palembang in southern Sumatra, dominated the maritime routes through the Straits of Malacca and Sunda, becoming a great centre of Buddhist learning. In central Java the Sailendra and Sanjaya dynasties raised two of the world's supreme religious monuments: the colossal Buddhist stupa of Borobudur, built around 780-850 CE, and the Hindu temple complex of Prambanan a little later.
Srivijaya's power waned from the eleventh century, eclipsed by Javanese states. In 1293 the kingdom of Majapahit arose in eastern Java and, under King Hayam Wuruk and his formidable chief minister Gajah Mada in the mid-fourteenth century, claimed influence over much of the archipelago, making it the most powerful of the pre-Islamic Indonesian realms. Majapahit declined through the fifteenth century as trade shifted and Islamic coastal states grew, but its memory became a touchstone of later Indonesian nationhood.
“Borobudur is the largest Buddhist monument in the world, a vast mandala in stone rising from the Javanese plain.”

The Spread of Islam and the Spice-Trade Sultanates
Carried largely by traders along the sea lanes, Islam spread through the archipelago, and as Majapahit faded a constellation of Muslim sultanates grew rich on the spice trade.
Islam reached the archipelago chiefly through Muslim merchants from India, Arabia and beyond, who frequented its ports along the great trade routes. The faith took root first in the coastal trading towns of northern Sumatra from around the thirteenth century, then spread gradually and largely peaceably along the maritime networks, gathering pace through the fifteenth century as rulers and their courts converted.
As the inland Hindu-Buddhist order of Majapahit weakened, power passed to a string of Muslim coastal sultanates that thrived as entrepôts in the trade between India, China and the Spice Islands. On Java the Sultanate of Demak became a foothold from which Islam spread across the island; in Sumatra the Sultanate of Aceh rose to prominence, while in the Maluku islands the sultanates of Ternate and Tidore controlled the world's only sources of cloves and nutmeg.
By the end of the sixteenth century Islam had become the dominant religion of Java and Sumatra, woven into local cultures rather than replacing them wholesale. This patchwork of trading sultanates, immensely wealthy from spices coveted in Europe, was the world into which Portuguese and then Dutch ships would sail in search of direct control of the spice trade.

Portuguese and Dutch Colonialism and the VOC
Lured by spices, Europeans seized the trade by force. After the Portuguese took Malacca, the Dutch East India Company built a commercial empire on monopoly, violence and the near-extermination of the Banda islanders.
European intrusion began in 1511, when the Portuguese admiral Afonso de Albuquerque captured the great entrepôt of Malacca, gaining a foothold in the Asian spice trade. The Portuguese reached the Maluku 'Spice Islands' but never dominated the archipelago, and in the seventeenth century they were displaced by a more ruthless and better-organised competitor.
In 1602 the Dutch Republic merged its competing traders into the Vereenigde Oost-Indische Compagnie (VOC), the Dutch East India Company, granting it quasi-sovereign powers to wage war, build forts, mint coins and make treaties. From its headquarters at Batavia (modern Jakarta), founded by Governor-General Jan Pieterszoon Coen in 1619, the VOC fought to impose a monopoly over the spice trade.
The pursuit of that monopoly was brutal. In 1621 Coen ordered a campaign against the Banda Islands, the world's sole source of nutmeg and mace, in which the great majority of the roughly fifteen thousand Bandanese were killed, starved or enslaved and the survivors deported. This act of mass killing, undertaken to secure commercial control, stands as one of the most notorious atrocities of European expansion in Asia.
For nearly two centuries the VOC extended its grip through war, alliance and coercion, draining wealth from the islands. By the late eighteenth century, weighed down by corruption, war and debt, the company was bankrupt. It was dissolved in 1799 and its territories and obligations passed to the Dutch state, opening the era of direct colonial rule.
“The almost total annihilation of the Bandanese was a clearly genocidal act committed to enforce the Dutch spice monopoly.”

The Dutch East Indies and the National Awakening
Under direct Dutch rule the islands became the Netherlands East Indies, exploited through forced cultivation; from this colonial order rose, in the early twentieth century, the first stirrings of Indonesian nationalism.
With the VOC gone, the archipelago became a colony governed directly from the Netherlands as the Dutch East Indies. From 1830 the colonial government imposed the Cultivation System (Cultuurstelsel), compelling Javanese peasants to devote land and labour to export crops such as coffee, sugar and indigo for the Dutch treasury. The system generated enormous profits for the Netherlands but brought hardship, dislocation and, in some districts, famine to the rural population.
Criticism of colonial exploitation, voiced in the Netherlands by works such as the novel Max Havelaar, helped prompt the early-twentieth-century 'Ethical Policy', which promised greater investment in welfare and education. Its expanded schooling, however, also produced a new educated Indonesian elite that began to question colonial rule itself.
Organised nationalism is often dated to 1908 and the founding of Budi Utomo, followed by the mass movement Sarekat Islam and, in 1927, Sukarno's Indonesian National Party. A defining moment came on 28 October 1928, when young activists proclaimed the Youth Pledge (Sumpah Pemuda), vowing allegiance to one motherland, one nation and one language, Indonesian. The Dutch responded with repression, imprisoning and exiling leaders, but a sense of a single Indonesian nation had taken hold.

Japanese Occupation, Independence and the Revolution
The Japanese occupation shattered Dutch prestige and armed a generation of nationalists; the Proclamation of 17 August 1945 launched a four-year revolution that ended in recognised independence.
In 1942 Imperial Japan swept the Dutch from the Indies in weeks, ending more than three centuries of European control. The occupation was harsh: hundreds of thousands of Indonesians were conscripted as romusha forced labourers, many of whom died, and the population endured shortages and repression. Yet the Japanese, needing local support, also promoted Indonesian leaders such as Sukarno and Hatta and trained a militia, PETA, that would form the core of a future national army.
When Japan surrendered in August 1945, nationalist youth pressed Sukarno and Hatta to act at once. On the morning of 17 August 1945 the two men proclaimed Indonesia's independence in Jakarta, and the following day Sukarno became president and Hatta vice-president of the new republic, which adopted the Pancasila state philosophy and a constitution.
The Dutch refused to accept the loss of their colony and sought to return, triggering the Indonesian National Revolution. Years of guerrilla warfare, diplomacy and two major Dutch military offensives, euphemistically called 'police actions', followed, marked by violence on both sides. International pressure, especially from the United States and the United Nations, ultimately forced the Netherlands to negotiate.
At the Round Table Conference in The Hague, the Netherlands agreed to transfer sovereignty, and on 27 December 1949 it formally recognised the independence of Indonesia. The republic had won, through revolution and diplomacy, the freedom it had proclaimed four years earlier.
“We the people of Indonesia hereby declare the independence of Indonesia.”

Sukarno, the New Order and Democratic Indonesia
The young republic moved from Sukarno's Guided Democracy into the violent birth of Suharto's New Order amid the mass killings of 1965-66, and after three decades of authoritarian rule became, from 1998, a vigorous democracy.
After independence, parliamentary politics gave way in the late 1950s to Sukarno's 'Guided Democracy', an increasingly authoritarian and nationalist order that balanced the army, religious parties and the large Indonesian Communist Party (PKI). Economic decline and political tension mounted through the early 1960s.
On the night of 30 September 1965 an abortive coup, in which several senior generals were killed, was blamed on the PKI. The army, led by Major-General Suharto, used it to unleash a campaign of mass killing against suspected communists and others. Across late 1965 and 1966 an estimated five hundred thousand to more than a million people were murdered, often by soldiers and local militias, in one of the worst mass atrocities of the twentieth century, a crime that for decades went unacknowledged and remains largely unaddressed in Indonesia.
From the wreckage Suharto sidelined Sukarno and consolidated power, formally becoming president in 1968 and ruling for over three decades as the 'New Order'. His regime delivered economic growth and stability but rested on authoritarian control, military dominance, suppression of dissent and entrenched corruption, alongside the long and bloody occupation of East Timor from 1975.
The Asian financial crisis of 1997-98 shattered the New Order's economic foundations. Amid mass protests, Suharto resigned on 21 May 1998, opening the era of Reformasi. Since then Indonesia has decentralised power, held free multiparty elections, and grown into the world's third-largest democracy, while continuing to grapple with corruption, inequality and the unfinished reckoning with its violent past.
“At least 500,000 people were killed, the total may be as high as one million.”
