Ayutthaya (/ɑːˈjuːtəjə/; Thai: อยุธยา, Thai pronunciation: [ʔajúttʰajaː]; also spelled Ayudhya) was a Siamese kingdom that existed from 1351 to 1767. Ayutthaya was friendly towards foreign traders, including the Chinese, Vietnamese, Indians, Japanese and Persians, and later the Portuguese, Spaniards, Dutch and French, permitting them to set up villages outside the walls of the capital, also called Ayutthaya. By 1550, the kingdom's vassals included some city-states in the Malay Peninsula, Sukhothai, and parts of Cambodia.
