Sumatra

Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is located entirely in Indonesia and the sixth-largest island in the world at 473,481 km2.
Southeast Asia

Southeast Asia or Southeastern Asia is a subregion of Asia, consisting of the regions that are geographically south of China, east of India and Bangladesh, north of Australia, and west of New Guinea. The region is the only part of Asia that lies partly within the Southern Hemisphere, although the majority of it is in the Northern Hemisphere. In contemporary definition, Southeast Asia consists of two geographic regions:
- Mainland Southeast Asia, also known historically as Indochina, comprising Myanmar, Thailand, Peninsular Malaysia, Laos, Cambodia, and Vietnam.
- Maritime Southeast Asia, also known historically as Nusantara, the East Indies, or the Malay Archipelago, comprising the Andaman and Nicobar Islands of India, Indonesia, East Malaysia, Brunei, Singapore, the Philippines, East Timor, Christmas Island, and the Cocos (Keeling) Islands.
Strait of Malacca

The Strait of Malacca or Straits of Malacca is a narrow, 550 mi (890 km) stretch of water between the Malay Peninsula and the Indonesian island of Sumatra. As the main shipping channel between the Indian Ocean and the Pacific Ocean, it is one of the most important shipping lanes in the world. It is named after the Malacca Sultanate that ruled over the archipelago between 1400 and 1511, which is the center of administration is located in the modern-day state of Malacca, Malaysia.
Srivijaya

Srivijaya, was a dominant thalassocratic Indonesian empire based on the island of Sumatra, Indonesia, which influenced much of Southeast Asia. Srivijaya was an important centre for the expansion of Buddhism from the 8th to the 12th century AD. Srivijaya was the first unified kingdom to dominate much of the Indonesian archipelago. The rise of the Srivijayan Empire was parallel to the end of the Malay sea-faring period. Due to its location, this once-powerful state developed complex technology utilizing maritime resources. In addition, its economy became progressively reliant on the booming trade in the region, thus transforming it into a prestige goods-based economy.
Malay Archipelago

The Malay Archipelago is the archipelago between mainland Indochina and Australia. It has also been called the Malay World, Nusantara, Indo-Australian Archipelago, East Indies, Spices Archipelago and other names over time. The name was taken from the 19th-century European concept of a Malay race, later based on the distribution of Austronesian languages.
Nusantara
Nusantara is the Indonesian/Malay name of Maritime Southeast Asia. It is an Old Javanese term which literally means "outer islands". In Indonesia, it is generally taken to mean the Indonesian archipelago, while in Malaysia the term has been adopted to mean the Malay archipelago.
Spice trade

The spice trade refers to the trade between historical civilizations in Asia, Northeast Africa and Europe. Spices such as cinnamon, cassia, cardamom, ginger, pepper, and turmeric were known and used in antiquity for commerce in the Eastern World. These spices found their way into the Middle East before the beginning of the Christian era, where the true sources of these spices were withheld by the traders and associated with fantastic tales.
Sundaland

Sundaland is a biogeographical region of Southeastern Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower. It includes the Malay Peninsula on the Asian mainland, as well as the large islands of Borneo, Java, and Sumatra and their surrounding small islands.
History of Kedah

Kedah, also written as Queda, and known in the early days as Qalha, Kalah Bar, Kalah or Kalaha by the Arabs and Persians, Cheh-Cha, Ka-Cha by the Chinese and Kedaram, Kidaram, Kalagam and Kataha by the Tamils, is an early kingdom on the Malay Peninsula and an important early trade centre. Early west-coast trade centres are few in number as they were overshadowed by Kedah. Her nearness to the entrances to the Straits of Malacca — and more importantly — being on latitude 6° north of the equator, the same as Ceylon to the south of India, meant that ships sailing the Bay of Bengal in a sea lane heading due east or west between the two were in little danger of becoming lost. The early transpeninsular routeway is part of the sea trade route of the Spice Route for Arab, Persian, Tamil Nadu and India-to-China traders, as the route through the Straits does not seem to have been in general use. Early sea traders from the west, upon reaching the coast, engaged porters to transport goods by raft, elephant and man-carry along the rivers to the opposite coast. The Sungai Muda in particular favoured the development of Kedah.
Austronesian peoples
The Austronesian peoples, or more accurately Austronesian-speaking peoples, are a large group of various peoples in Southeast Asia, Taiwan, Oceania, and Madagascar that speak the Austronesian languages. The nations and territories predominantly populated by Austronesian-speaking peoples are known collectively as Austronesia. They originate from a prehistoric seaborne migration from 3000 to 1500 BCE known as the Austronesian expansion.
Malay race

The concept of a Malay race was originally proposed by the German physician Johann Friedrich Blumenbach (1752–1840), and classified as a brown race. Malay is a loose term used in the late 19th century and early 20th century to describe the Austronesian peoples or to categorize Austronesian speakers into a race.
East Indian Archipelago

The East Indian Archipelago (Indonesia) is an area designated by the International Hydrographic Organization (IHO). It encompasses twelve seas, two gulfs, and one strait in the East Indies.
Malay world

The Malay world or Malay realm, is a concept or an expression that has been utilised by different authors and groups over time to denote several different notions, derived from varied interpretations of Malayness, either as a racial category, as a linguistic group or as a political-cultural group. The use of the term 'Malay' in much of the conceptualisation is largely based on the prevalent Malay cultural influence, manifested in particular through the spread of Malay language in Southeast Asia as observed by different colonial powers during the Age of Discovery.
Names of Indonesia

Indonesia is the common and official name to refer the Republic of Indonesia or Indonesian archipelago; however, other names, such as Nusantara and East Indies are also known. Some names are considered obsolete and confined to certain periods of history, while some might be more geographically specific or general.
Chola invasion of Srivijaya

In 1025, Rajendra Chola I, the Chola king from Tamil Nadu in South India, launched naval raids on the city-state of Srivijaya in maritime Southeast Asia, and conquered Kadaram from Srivijaya and occupied it for some time. Rajendra's overseas expedition against Srivijaya was a unique event in India's history and its otherwise peaceful relations with the states of Southeast Asia. Several places in Malaysia and Indonesia were invaded by Rajendra Chola I of the Chola dynasty. The Chola invasion furthered the expansion of Tamil merchant associations such as the Manigramam, Ayyavole and Ainnurruvar into Southeast Asia. The Chola invasion led to the fall of the Sailendra Dynasty of Srivijaya and the Chola invasion also coincides with return voyage of the great Buddhist scholar Atiśa from Sumatra to India and Tibet in 1025. The expedition of Rajendra Chola I is mentioned in the corrupted form as Raja Chulan in the medieval Malay chronicle Sejarah Melaya, and Malay princes have names ending with Cholan or Chulan, such as Raja Chulan of Perak.
Lesser Sunda Islands

The Lesser Sunda Islands are a group of islands in Maritime Southeast Asia, north of Australia. Together with the Greater Sunda Islands to the west they make up the Sunda Islands. The islands are part of a volcanic arc, the Sunda Arc, formed by subduction along the Sunda Trench in the Java Sea.
Maritime Silk Road
The Maritime Silk Road or Maritime Silk Route refers to the maritime section of the historic Silk Road that connected China, Southeast Asia, the Indian subcontinent, Arabian peninsula, Somalia, Egypt and Europe. It flourished between the 2nd century BCE and 15th century CE. Despite its association with China in recent centuries, the Maritime Silk Road was primarily established and operated by Austronesian sailors in Southeast Asia, Tamil merchants in India and Southeast Asia, Greco-Roman merchants in East Africa, India, Ceylon and Indochina, and by Persian and Arab traders in the Arabian Sea and beyond.
