Southeast Asia consists of the 11 countries that lie between the Indian subcontinent and China. On the mainland of Southeast Asia are Myanmar (Burma), Thailand, Laos, Cambodia, and Vietnam. Insular Southeast Asia includes Indonesia, the Philippines, Brunei, Malaysia, Singapore, and most recently Timor Leste. The largest part of Malaysia is on the mainland (Peninsular Malaysia), but the country is considered culturally closer to insular Southeast Asia because the majority Malay population shares a common language and religion with Indonesia. The city‐state of Singapore (on an island connected by a mile‐long causeway to Peninsular Malaysia) was historically part of Malaysia, but because of its unique ethnic composition (three quarters of the population is of Chinese origin) it is more similar to East Asia than Southeast Asia. Diversity is the hallmark of the region. Incredible indigenous cultural variation has been overlaid with centuries of contact, trade, migration, and cultural exchange within the region, from other parts of Asia, and for the past 500 years from Europe.
