From Halopedia, the Halo wiki
Ancient Egyptian civilization coalesced over 6,000 years prior to the end of the Covenant war.[Note 1] After the eventual unification of Earth's nations under the Unified Earth Government, Egypt's strategic location became vitally important to the United Nations Space Command. A Moncton-class orbital weapon platform was constructed to orbit its capital city geosynchronously and when the Covenant attacked in 2552, Cairo Station served as flag headquarters. Fighting during the Battle of Earth took place in Cairo itself.
Economy and Society
