Thai people in general are somewhat nostalgic about this period in their history. Sukhothai is viewed as an era of prosperity and good governance. After the death of King Ramkhamhaeng the Great, the sphere of influence of Sukhothai decreased, and parts of the Kingdom gained autonomy.
Meanwhile, the Kingdom of Ayutthaya (1350-1767 A.D.) gained in influence. Already in 1378 King Thammaracha II had to submit to the power of Ayutthaya. After the death of the last King of Sukhothai (King Thammaracha IV who moved his capital to Phitsanulok) in 1438, Sukhothai became just a province of the Kingdom of Ayutthaya.
In economic terms, production of glazed ceramic wares, was very important. Numerous kilns dotted the landscape around Sukhothai and its sister city Sri Satchanalai. Ceramic wares, such as plates, bowls, jars were exported to various countries in South-East Asia. Even up to this date, new finds are common, especially from sunken trading vessels in the Gulf of Thailand.
