The Second Midwayan Civil War was a military conflict that succeeds the Midwayan Civil War and was part of the long series of conflicts known as the Jihad War of the United States of JBR. It began when the United States of JBR declared war on the Midwayan Soviet Federative Socialist Republic (East Midway) on May 10, 2011 after the Congress of the United States of JBR and People's Branch of the United States of JBR approved a proposal for war. Within minutes of the announcement, the Midwayan Soviet Federative Socialist Republic declared war on the United States of JBR and the Union of Midway; the latter being declared due to the Republic's claims that the Midwayan Armistice was broken. Later on the same day, the Deltoran Republic and Pacific Empire declared war on East Midway.
