Southeast Asia is a diverse region divided into a mainland area (like Vietnam and Thailand) and a maritime area (like Indonesia and the Philippines).

Its strategic location on the trade routes between India and China has shaped its history.

The region was heavily influenced by Indian culture, leading to the rise of 'Indianized' kingdoms that adopted Hinduism and Buddhism.

Great ancient empires of the region include the Khmer Empire in Cambodia, which built the magnificent temple complex of Angkor Wat, and the Srivijaya Empire, a maritime power based in Sumatra.

Islam spread to maritime Southeast Asia through trade, and today Indonesia is the world's most populous Muslim country.

Beginning in the 16th century, European powers began to colonize the region, with the British, French, Dutch, and Spanish all establishing colonies.

Only Thailand (Siam) managed to avoid formal colonization.

The 20th century was marked by struggles for independence from colonial rule, most notably the Vietnam War.

Many Southeast Asian nations experienced rapid economic growth in the late 20th century.

The region is organized politically through the Association of Southeast Asian Nations (ASEAN).
