Burmese–Siamese War (1765–1767)

The Burmese–Siamese War of 1765–1767, also known as the war of the second fall of Ayutthaya (Thai: สงครามคราวเสียกรุงศรีอยุธยาครั้งที่สอง) was the second military conflict between Burma under the Konbaung dynasty and Ayutthaya Kingdom under the Siamese Ban Phlu Luang dynasty that lasted from 1765 until 1767; the war ended the 417-year-old Ayutthaya Kingdom. Burma under the new Konbaung dynasty emerged powerful in the mid-18th century.
