The Andaman Islands are a group of islands located in the Bay of Bengal between India and Burma. The islands have been inhabited for thousands of years by indigenous tribes. They were colonized by the British in the 18th century, who established a penal colony on the islands. During World War 2, the islands were occupied by Japan. Today, the islands form a union territory of India with the capital in Port Blair. The islands were impacted by the 2004 Indian Ocean tsunami.
