Which country was formerly named Persia?

Bangladesh. Between 1947-1971, the current country of Bangladesh was a part of Pak­istan, known as the East Pak­istan. It was the largest, the most pop­u­lat­ed and the richest region of Pak­istan, com­plete­ly sep­a­rat­ed from the rest of the country. In 1971, after 9-­mon­th-­long war for in­de­pen­dence, the province was changed into the in­de­pen­dent country of Bangladesh.

Tehran. From the 1920s to 1930s, the city was es­sen­tial­ly rebuilt from scratch, under the rule of Reza Shah Pahlavi. In an attempt to mod­ern­ize the city, many historic build­ings, for­ti­fi­ca­tions and gardens were de­mol­ished, and modern build­ings in pre-Is­lam­ic Iranian style (such as National Bank) were built in their place.

Kabul. The Soviets turned the city of Kabul into their command center during the Soviet war in Afghanistan. Kabul was con­sid­ered mod­er­ate­ly safe during that period. However, about 80 percent of the city was de­stroyed during the civil war between dif­fer­ent mu­jahideen fac­tion­s, which broke out after Soviet's retreat.

Myanmar. In 1989, the military gov­ern­ment of­fi­cial­ly changed the English trans­la­tions of many names dating back to Burma's colonial period or earlier, in­clud­ing that of the country itself: "Burma" became "Myan­mar". Both these names are derived from the name of the majority Burmese Bamar ethnic group. Myanmar is con­sid­ered to be the literary form of the name of the group, while Burma is derived from "Bamar", the col­lo­qui­al form of the group's name.
