Sukhothai was the first capital of Siam. Established in the 13th century, Sukhothai’s dynasty lasted 200 years and had nine kings. The most famous was King Ramkhamhaeng, who reigned from 1275 to 1317 and is credited with developing the first Thai script – his inscriptions are considered the first Thai literature. He also expanded the kingdom to include almost all of present-day Thailand. But a few kings later in 1438, Sukhothai was absorbed by Ayuthaya. See Sukhothai Historical Park for more information.
