When talking about Sukhothai, people usually refer to the Sukhothai Historical Park, also known as Old Sukhothai City, a UNESCO World Heritage Site, located 300km south of Chiang Mai in the central plains region and one of Thailand’s most visited ancient sites.
According to legend, Sukhothai was founded in the 13th century, when two brothers, known as Pho Khun Bangklanhao and Pho Khun Phameung, took over the kingdom from the Khmer, a then major frontier post of the Angkor Empire. Over the following years, Sukhothai was drastically expanded until Muang Sua (Luang Prabang), parts of southern Burma and South Thailand and established even political ties with China during its Yuan Dynasty. The name Sukhothai means ‘Dawn of Happiness’.
The Sukhothai-era however only lasted a brief 140 years, until armies of the Ayutthaya kingdom took tributary over Sukhothai.
