Lower Burma

Lower Burma is a historical region, referring to the part of Burma annexed by the British Empire after the Second Anglo-Burmese War, which took place in 1852, plus the former kingdom of Arakan and the territory of Tenasserim which the British had taken control of in 1826. Lower Burma was centred at Rangoon, and composed of all of the coast of modern Myanmar, and also the lower basin of Irrawaddy river, including Prome. The area was also known as British Burma. Lower Burma was predominantly populated by Mon, Karen, and Bamar.
