In 1583, Sukhothai is restored as a province within the Ayutthaya Kingdom after King Naresuan of Phitsanulok (and crown prince of Ayutthaya) won the combat with prince Mingyi Swa of Burma who died in single combat at Don Chedi in 1592. (wikipedia.org)

Ayutthaya Kingdom (1351 – 1767)

Thai history sometimes called it “Ayothaya“.

Ayutthaya was described by foreign traders as one of the biggest and wealthiest cities in the East. It 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“.
