Starting in the 7th century Lampang was part of the
Dvaravati period Haripunchai kingdom of the Mon. In the
11th century the Khmer empire occupied the Lampang area,
but it was King Mengrai of Lannathai who incorporated
the complete Haripunchai kingdom into his kingdom in
1292. After the fall of Lannathai it was under Burmese
rulership, and finally became part of Thailand in 1774.
