Malay archipelago

The Malay Archipelago (Indonesian and Malay: Kepulauan Melayu/Nusantara, Tagalog: Kapuluang Malay, Visayan: Kapupud-ang Malay) is the archipelago between mainland Indochina and Australia. It has also been called the Malay World, Indo-Australian Archipelago, East Indies, Nusantara, 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.

Situated between the Indian and Pacific Oceans, the group of over 25,000 islands is the largest archipelago by area and fourth by number of islands in the world. It includes Brunei, Singapore, East Malaysia, Indonesia, the Philippines and East Timor. The term is largely synonymous with maritime Southeast Asia.

Etymology and terminology
The term was derived from the European concept of a Malay race, which referred to the people who inhabited what is now Brunei, Singapore, Malaysia, Indonesia (excluding Western New Guinea), the Philippines and East Timor. The racial concept was proposed by European explorers based on their observations of the influence of the ethnic Malay empire, Srivijaya, which was based on the island of Sumatra, Indonesia. The 19th-century naturalist Alfred Wallace used the term "Malay Archipelago" as the title of his influential book documenting his studies in the region. Wallace also referred to the area as the "Indian Archipelago" and the "Indo-Australian" Archipelago. He included within the region the Solomon Islands and the Malay Peninsula due to physiographic similarities. As Wallace noted, there are arguments for excluding Papua New Guinea for cultural and geographical reasons: Papua New Guinea is culturally quite different from the other countries in the region, and it is geologically not part of the continent of Asia, as the islands of the Sunda Shelf are (see Australia).

The archipelago was called the "East Indies" from the late 16th century and throughout the European colonial era. It is still sometimes referred to as such, but broader usages of the "East Indies" term had included Indochina and the Indian subcontinent. The area is called "Nusantara" in the Indonesian language. The area is also referred to as the "Indonesian archipelago". The term "maritime Southeast Asia" is largely synonymous, covering both the islands in Southeast Asia and nearby island-like communities, such as those found on the Malay Peninsula.

Geography
The land and sea area of the archipelago exceeds 2 million km2. The more than 25,000 islands of the archipelago comprise many smaller archipelagoes.

The major groupings are:
 * Indonesia
 * Sunda Islands
 * Greater Sunda Islands
 * Lesser Sunda Islands
 * Maluku Islands
 * Philippine Archipelago
 * Visayan Islands
 * New Guinea and surrounding islands (when included)

The seven largest islands are New Guinea, Borneo, Sumatra, Sulawesi and Java in Indonesia; and Luzon and Mindanao in the Philippines.

Geologically, the archipelago is one of the most active volcanic regions in the world. Producing many volcanoes especially in Java, Sumatra and Lesser Sunda Islands region where most volcanoes over 3000 m situated. Tectonic uplifts also produced large mountains, including the highest in Mount Kinabalu in Sabah, Malaysia, with a height of 4,095.2 m and Puncak Jaya on Papua, Indonesia at 4884 m. Other high mountains in the archipelago include Puncak Mandala, Indonesia at 4760 m and Puncak Trikora, Indonesia, at 4750 m.

The climate throughout the archipelago is tropical, owing to its position on the equator.

Biogeography


Wallace used the term Malay Archipelago as the title of his influential book documenting his studies in the region. He proposed what would come to be known as the "Wallace Line", a boundary that separated the flora and fauna of Asia and Australia. The ice age boundary was formed by the deep water straits between Borneo and Sulawesi; and through the Lombok Strait between Bali and Lombok. This is now considered the western border of the Wallacea transition zone between the zoogeographical regions of Asia and Australia. The zone has a mixture of species of Asian and Australian origin, and its own endemic species.

Demography
Over 380 million people live in the region, with the 12 most populated islands being:


 * Java (141,000,000)
 * Sumatra (50,180,000)
 * Luzon (48,520,774)
 * Mindanao (21,902,000)
 * Borneo (21,258,000)
 * Sulawesi (21,258,000)
 * New Guinea (11,818,000)
 * Singapore (5,535,000)
 * Negros (4,414,131)
 * Panay (4,307,000)
 * Bali (4,225,384)
 * Cebu (3,979,155)

The people living there are predominantly from Austronesian subgroupings and correspondingly speak western Malayo-Polynesian languages. The main religions in this region are Islam, Christianity, Buddhism, Hinduism and traditional animism.

Culturally, the region is often seen as part of "Farther India" or Greater India—the Coedes Indianized states of Southeast Asia refers to it as "Island Southeast Asia".
