The Konbaung dynasty (ကုန်းဘောင်မင်းဆက်), also known as Third Burmese Empire (တတိယမြန်မာနိုင်ငံတော်), was the last dynasty that ruled Burma/Myanmar from 1752 to 1885. It created the second-largest empire in Burmese history and continued the administrative reforms begun by the Toungoo dynasty, laying the foundations of the modern state of Burma. The reforms, however, proved insufficient to stem the advance of the British, who defeated the Burmese in all three Anglo-Burmese Wars over a six-decade span (1824–1885) and ended the millennium-old Burmese monarchy in 1885. Pretenders to the dynasty claim descent from Myat Phaya Lat, one of Thibaw's daughters.
An expansionist dynasty, the Konbaung kings waged campaigns against Manipur, Arakan, Assam, the Mon kingdom of Pegu, Siam (Ayutthaya, Thonburi, Rattanakosin), and the Qing dynasty of China – thus establishing the Third Burmese Empire. Subject to later wars and treaties with the British, the modern state of Myanmar can trace its current borders to these events.
Throughout the Konbaung dynasty, the capital was relocated several times for religious, political, and strategic reasons.
The dynasty was founded by a village chief, who later became known as Alaungpaya, in 1752 to challenge the Restored Hanthawaddy Kingdom which had just toppled the Taungoo dynasty. By 1759, Alaungpaya's forces had reunited all of Burma (and Manipur) and driven out the French and the British who had provided arms to Hanthawaddy.
Alaungpaya's second son, Hsinbyushin, came to the throne after a short reign by his elder brother, Naungdawgyi (1760–1763). He continued his father's expansionist policy and finally took Ayutthaya in 1767, after seven years of fighting.
In 1760, Burma began a series of wars with Siam that would last well into the middle of the 19th century. By 1770, Alaungpaya's heirs had destroyed Ayutthaya Siam (1765–1767), subdued much of Laos (1765) and defeated four invasions by Qing China (1765–1769).
