Has Myanmar ever been in a war?

Answer 1

Yes.

Myanmar, also known as Burma, was conquered by the British after three Anglo-Burmese Wars in the 19th century.

Burma became an independent nation in 1948, initially as a democratic nation and then, following a coup in 1962, a military Dictatorship which formally ended in 2011.

The country has been engrossed in rampant ethnic strife for most of its independent years, and a myriad of Burma's ethnic groups have been involved in one of the world's longest-running unresolved civil wars.
