Unified Political Command

A Unified Political Command (Arabic: قيادة سياسية موحدة, qiyāda siyāsiyya muwaḥḥada), also translated as Joint Political Command or Unified Political Leadership, was agreed in 1964 between the presidents of Egypt and Iraq (Gamal Abdel Nasser and Abdul Salam Arif) as well as between the presidents of Egypt and North Yemen (Nasser and Abdullah as-Sallal). Both projects were parallel but not linked with each other.
