1750s in Thailand

The Ayutthaya Kingdom or the Empire of Ayutthaya was a Mon and later Siamese kingdom that existed in Southeast Asia from 1351 to 1767, centered around the city of Ayutthaya, in Siam, or present-day Thailand. European travellers in the early 16th century called Ayutthaya one of the three great powers of Asia (alongside Vijayanagara and China). The Ayutthaya Kingdom is considered to be the precursor of modern Thailand, and its developments are an important part of the history of Thailand.

The Burmese–Siamese War (1759–1760) (Burmese: ယိုးဒယား-မြန်မာစစ် (၁၇၅၉–၁၇၆၀); Thai: สงครามพม่า-สยาม (พ.ศ. 2302–2303)) or Alaungpaya's War (Thai: สงครามพระเจ้าอลองพญา) was the military conflict between the Konbaung dynasty of Burma (Myanmar) and the Ban Phlu Luang Dynasty of the Ayutthaya Kingdom of Siam, in which the Burmese forces under King Alaungpaya of the Konbaung dynasty invaded Siam. After about a century of relative hiatus of Burmese–Siamese conflicts, this war reignited the new round of military conflicts between Burma and Siam that would last for about a century to come.
