with the British and downfall Faced with a powerful China and a resurgent Siam in the east, Bodawpaya acquired western kingdoms of Arakan (1784), Manipur (1814) and Assam (1817), leading to a long ill-defined border with British India. Europeans began to set up trading posts in the Irrawaddy delta region during this period. Konbaung tried to maintain its independence by balancing between the French and the British. In the end it failed, the British severed diplomatic relations in 1811, and the dynasty fought and lost three wars against the British Empire, culminating in total annexation of Burma by the British. The British defeated the Burmese in the First Anglo-Burmese War (1824–1826) after huge losses on both sides, both in terms of manpower and financial assets. Burma had to cede Arakan, Manipur, Assam and Tenasserim, and pay a large indemnity of one million pounds. In 1837, King Bagyidaw's brother, Tharrawaddy, seized the throne, put Bagyidaw under house arrest and executed the chief queen Me Nu and her brother. Tharrawaddy made no attempt to improve relations with Britain. His son Pagan, who became king in 1846, executed thousands – some sources say as many as 6,000 – of his wealthier and more influential subjects on trumped-up charges. During his reign, relations with the British became increasingly strained. In 1852, the Second Anglo-Burmese War broke out. Pagan was succeeded by his younger brother, the progressive Mindon. Mindon attempted to bring Burma into greater contact with the outside world, and hosted the Fifth Great Buddhist Synod in 1872 at Mandalay, gaining the respect of the British and the admiration of his own people. Mindon avoided annexation in 1875 by ceding the Karenni States. He died before he could name a successor, and Thibaw, a lesser prince, was manoeuvred onto the throne by Hsinbyumashin, one of Mindon's queens, together with her daughter, Supayalat. (Rudyard Kipling mentions her as Thibaw's queen, and borrows her name, in his poem "Mandalay") The new King Thibaw proceeded, under Supayalat's direction, to massacre all likely contenders to the throne. This massacre was conducted by the queen. The dynasty came to an end in 1885 with the forced abdication and exile of the king and the royal family to India. The British, alarmed by the consolidation of French Indochina, annexed the remainder of the country in the Third Anglo-Burmese War in 1885. The annexation was announced in the British parliament as
