The breadth of this empire was short-lived. In 1826, Burma lost Arakan, Manipur, Assam and Tenasserim to the British in the First Anglo-Burmese War. In 1852, the British easily seized Lower Burma in the Second Anglo-Burmese War. King Mindon Min tried to modernise the kingdom and in 1875 narrowly avoided annexation by ceding the Karenni States. The British, alarmed by the consolidation of French Indochina, annexed the remainder of the country in the Third Anglo-Burmese War in 1885.
