The Egyptian-Islamic State War was a conflict fought between the Kingdom of Egypt and the Islamic State of Iraq and the Levant.
The war stemmed from the assassination of Egyptian King, Aahil, on February 2nd, 2069. Aahil, his family and three civilians were killed in a drive-by shooting as they were leaving a building in Cairo. Laiba (who later assumed the name, Nefertiti II) took the throne and swore vengeance. After a week, Nefertiti announced that the results of an "investigation" revealed that the hitmen were members of the Islamic State. Egypt invaded Jordan and began striking IS cities immediately afterwards.
On May 10th, 2071, IS Caliph, Abu Rahim al-Anbari, was assassinated by EAF troops in his bunker. By that time, all that remained for an Egyptian victory, was the capture of Syria.
On April 21st, 2072, Egypt captured Syria and ended the war. The U.N, a long time enemy of the IS, congratulated Egypt, but asked them to restore government to the captured nations and militarly withdraw. Egypt claimed that they would exit, but only after a decade-long withdrawal plan.
Egypt's victory in this war was the catalyst for their later superpower status.
