In 1988, unrest over economic mismanagement and political oppression by the government led to widespread pro-democracy demonstrations throughout the country known as the 8888 Uprising. Security forces killed thousands of demonstrators, and General Saw Maung staged a coup d'etat and formed the State Law and Order Restoration Council (SLORC). In 1989, SLORC declared martial law after widespread protests. The military government finalised plans for People's Assembly elections on 31 May 1989. SLORC changed the country's official English name from the "Socialist Republic of the Union of Burma" to the "Union of Myanmar" in 1989.
