Overview
Long before the Tai kingdoms, present-day Thailand hosted some of Southeast Asia’s earliest bronze metallurgy. At Ban Chiang in the northeast (Udon Thani area), settlement began well before 1000 BC, and its bronze artifacts are commonly dated from c. 1500 BC — a dating long debated, with early claims placing it millennia earlier before later revision. The site, famous for its painted pottery, was inscribed as UNESCO World Heritage in 1992.
Key developments
The Mon-speaking, Theravada-Buddhist Dvaravati culture flourished in the Chao Phraya basin from the 6th to the 11th century, leaving moated towns, with Nakhon Pathom among its centers. The peninsular south lay in the orbit of the maritime empire of Srivijaya (roughly 7th–13th centuries). The Khmer Empire (Angkor) ruled much of central and northeastern Thailand from about the 10th to the 13th century, building temple complexes at Phimai and elsewhere, with Lopburi a major regional center. Meanwhile, Tai-speaking peoples migrated gradually southwest from what is now southern China over many centuries, settling the river valleys and forming local principalities known as mueang.
End and transition
In the 13th century, as Angkor’s reach receded, Tai lords founded independent kingdoms — Sukhothai (trad. 1238) and Lan Na, whose capital Chiang Mai was founded in 1296 — opening the era of the Tai states.
