Invasion of Ayutthaya Kingdom

Date: October 14, 1548 • Location: Martaban, Myanmar

This milestone marked the outbreak and beginning of this historic period, which spanned 1547–1549.

Forces of the Burmese Toungoo dynasty led by King Tabinshwehti (depicted) departed Martaban to begin an invasion of the Ayutthaya Kingdom.

The Toungoo dynasty, also spelt Taungoo dynasty and also known as the Nyaungyan dynasty (ညောင်ရမ်းမင်းဆက်) after 1599, was the ruling dynasty of Burma (Myanmar) from the mid-16th century to 1752. It is also called the Second Burmese Empire (ဒုတိယမြန်မာနိုင်ငံတော်) in Burmese historiography. At its peak, Toungoo "exercised suzerainty from present-day Assam, Manipur to the Cambodian marches and from the borders of Arakan to Yunnan" and was "probably the largest empire in the history of Southeast Asia." The dynasty ruled in two periods: the First Toungoo Empire (1510–1599) and the Nyaungyan Restoration (1599–1752).
