[7][8] In Maritime Southeast Asia, apart from exceptions such as Borneo and Sumatra, the patchwork of recurring land-sea patterns on widely dispersed islands and archipelagos admitted moderately sized thalassocratic states indifferent to territorial ambitions, where growth and prosperity were associated with sea trade.
[9] Since around 100 BCE, Maritime Southeast Asia has occupied a central position at the crossroads of the Indian Ocean and the South China Sea trading routes, immensely stimulating its economy and influencing its culture and society.
[20] The term was officially used to designate the area of operation (the South East Asia Command, SEAC) for Anglo-American forces in the Pacific Theater of World War II from 1941 to 1945.
[34] Distinctive Basal-East Asian (East-Eurasian) ancestry was recently found to have originated in Mainland Southeast Asia at ~50,000 BCE, and expanded through multiple migration waves southwards and northwards respectively.
[3] Ocean drops of up to 120 m (393.70 ft) below the present level during Pleistocene glacial periods revealed the vast lowlands known as Sundaland, enabling hunter-gatherer populations to freely access insular Southeast Asia via extensive terrestrial corridors.
Modern human presence in the Niah cave on East Malaysia dates back to 40,000 years BP, although archaeological documentation of the early settlement period suggests only brief occupation phases.
Items found there such as burial jars, earthenware, jade ornaments and other jewellery, stone tools, animal bones and human fossils date back to 47,000 years BP.
[37] Signs of an early tradition are discernible in the Hoabinhian, the name given to an industry and cultural continuity of stone tools and flaked cobble artefacts that appear around 10,000 BP in caves and rock shelters first described in Hòa Bình, Vietnam, and later documented in Terengganu, Malaysia, Sumatra, Thailand, Laos, Myanmar, Cambodia and Yunnan, southern China.
Due to their early invention of ocean-going outrigger boats and voyaging catamarans, Austronesians rapidly colonized Island Southeast Asia, before spreading further into Micronesia, Melanesia, Polynesia, Madagascar and the Comoros.
[47][failed verification] Territorial principalities in both Insular and Mainland Southeast Asia, characterised as Agrarian kingdoms,[49] developed an economy by around 500 BCE based on surplus crop cultivation and moderate coastal trade of domestic natural products.
[51][52] Intensive wet-rice cultivation in an ideal climate enabled the farming communities to produce a regular crop surplus that was used by the ruling elite to raise, command and pay work forces for public construction and maintenance projects such as canals and fortifications.
[54][55][56][57] The earliest known evidence of copper and bronze production in Southeast Asia was found at Ban Chiang in north-east Thailand and among the Phùng Nguyên culture of northern Vietnam around 2000 BCE.
Among large, thin-walled terracotta jars, ornamented and colorized cooking pots, glass items, jade earrings and metal objects were deposited near the rivers and along the coast.
[62] The Buni culture is the name given to another early independent centre of refined pottery production that has been well documented on the basis of excavated burial gifts, deposited between 400 BCE and 100 CE in coastal north-western Java.
The concept of "Indianised kingdoms", a term coined by French scholar George Cœdès, describes how Southeast Asian principalities incorporated central aspects of Indian institutions, religion, statecraft, administration, culture, epigraphy, writing and architecture.
Numerous coastal communities in maritime Southeast Asia adopted Hindu and Buddhist cultural and religious elements from India and developed complex polities ruled by native dynasties.
This tributary system was based on the Chinese worldview that had developed under the Shang dynasty, in which China was deemed the center and apogee of culture and civilization, the "Middle kingdom" (Mandarin: 中国, Zhōngguó), surrounded by several layers of increasingly barbarous peoples.
[83] Between the 2nd-century BCE and 15th-century CE, the Maritime Silk Road flourished, connecting China, Southeast Asia, the Indian subcontinent, the Arabian Peninsula, Somalia and all the way to Egypt and Europe.
[85] Despite its association with China in recent centuries, the Maritime Silk Road was primarily established and operated by Austronesian sailors in Southeast Asia and by Persian and Arab traders in the Arabian Sea.
Pilgrims and wandering monks from Sri Lanka introduced Theravada Buddhism in the Pagan Empire of Burma, the Sukhothai Kingdom in northern Thailand and Laos, the Lower Mekong Basin during Cambodia's dark ages and further into Vietnam and Maritime Southeast Asia.
These advancements also aided the Chola dynasty of Tamilakam, Southern India, in carrying out a series of destructive attacks on Srivijaya, effectively ending Palembang's entrepôt position in the Indo-Chinese trade route.
In the late 8th and early 9th centuries, the Śailendra dynasty that ruled the Mataram kingdom built a number of massive monuments in Central Java, including the Sewu and Borobudur Buddhist temples.
The Khmer Empire covered much of mainland Southeast Asia from the early 9th until the 15th century, during which time a sophisticated architecture was developed, exemplified in the structures of the capital city Angkor.
[122] Unlike some other "Islamised" regions like North Africa, Iberia, the Middle East and later northern India, Islamic faith in Southeast Asia was not enforced in the wake of territorial conquests, but because of trade routes.
The ruling Yongle Emperor resolved to focus on the Indian Ocean sea routes, seeking to consolidate the ancient Imperial Tributary System, establish greater diplomatic and military presence, and widen the Chinese sphere of influence.
Under the leadership of Zheng He, hundreds of naval vessels of then unparalleled size, grandeur, and technological advancement and manned by sizeable military contingents, ambassadors, merchants, artists and scholars repeatedly visited major Southeast Asian principalities.
The protraction of the ritualistic ceremonies and scanty travels of emissaries in the Tributary System alone was not sufficient to develop firm and lasting Chinese commercial and political influence in the region, especially during the impending onset of highly competitive global trade.
In 1786, the settlement of George Town was founded at the northeastern tip of Penang Island by Captain Francis Light, under the administration of Sir John Macpherson; this marked the beginning of British expansion into the Malay Peninsula.
[134][135] By 1913, the British had occupied Burma, Malaya and the northern Borneo territories, the French controlled Indochina, the Dutch ruled the Netherlands East Indies while Portugal managed to hold on to Portuguese Timor.
In the Treaty of Paris of 1898 that ended the war with Spain, the United States gained the Philippines and other territories; in refusing to recognise the nascent republic, America effectively reversed her position of 1856.
