Ayutthaya Besieges Chiang Mai

1526

The Siamese kingdom of Ayutthaya, wealthy from rice and Chinese trade, pressed northward against the Tai kingdom of Lan Na. Elephant corps and Chinese-style walled encampments collided outside Chiang Mai. The long struggle over the Ping River valley foreshadowed the coming century of Burmese and Siamese war. The rivalry would continue through multiple invasions until Burmese conquest rendered both kingdoms subordinate.
