إيالة مصر
Arabic (alongside English) was an official language in South Sudan from 1863 (these days a part of Egypt Eyalet (1517–1867)) until 2011 (that time the independent state Republic of South Sudan), when the former government canceled Arabic as an official language. Since 2011 English is the sole official language of South Sudan. The Arabic dialect Juba Arabic is still the lingua franca of the people in South Sudan.
