Republic of South Sudan in the context of "Sudd"

The Anglo-Egyptian Sudan (Arabic: السودان الإنجليزي المصري as-Sūdān al-Inglīzī al-Maṣrī) was a condominium of the United Kingdom and Egypt between 1899 and 1956, corresponding to the territory of what is now both Sudans and parts of southeastern Libya. Legally, sovereignty and administration were shared between both Egypt and the United Kingdom, but in practice the structure of the condominium ensured effective British control over Sudan, with Egypt having limited local power and influence. In the meantime, Egypt itself fell under increasing British influence. Following the Egyptian Revolution of 1952, Egypt pushed for an end to the condominium, and the independence of Sudan. By agreement between Egypt and the United Kingdom in 1953, Sudan was granted independence as the Republic of the Sudan on 1 January 1956. In 2011, the south of Sudan itself became independent as the Republic of South Sudan.

Muhammad Ali took control of Egypt in 1805, and while he was nominally a vassal of the Ottoman Empire, Egypt under his rule acted as a virtually independent state. Seeking to supplant and ultimately replace the Ottoman Empire as the dominant regional power, Muhammad Ali declared himself Khedive, and expanded Egypt's borders both southwards into Sudan, and eastwards into the Levant and Arabia, the latter at the expense of the Ottoman Empire. Territory in Sudan was annexed by Egypt, and governed as an integral part of the country, with Sudanese granted Egyptian citizenship. Ultimately, the intervention of the Great Powers in support of the Ottoman Empire forced Egypt to return all Levantine and Arabian territory to the Ottomans upon Muhammad Ali's death. However, there was no such impediment to Egypt's southward expansion.

The Southern Sudan Autonomous Region was an autonomous region that existed in southern Sudan between 1972 and 1983. It was established on 28 February 1972 by the Addis Ababa Agreement which ended the First Sudanese Civil War. The region was abolished on 5 June 1983 by the administration of Sudanese President Gaafar Nimeiry. Revocation of southern autonomy was one of the causes of the Second Sudanese Civil War which would continue until January 2005, when southern autonomy was restored; the region became the independent Republic of South Sudan in 2011.

Southern Sudan (Arabic: حكومة جنوب السودان Ḥukūmat Janūb as-Sūdān; Dinka: Lɔ̈k Bïkrotmac Paguot Thudän) was an autonomous region consisting of the ten southern states of Sudan between its formation in July 2005 and independence as the Republic of South Sudan in July 2011. The autonomous government was initially established in Rumbek and later moved to Juba. It was bordered by Ethiopia to the east; Kenya, Uganda, and the Democratic Republic of the Congo to the south; and the Central African Republic to the west. To the north lies the predominantly Arab and Muslim region directly under the control of the central government. The region's autonomous status was a condition of a peace agreement between the Sudan People's Liberation Army/Movement (SPLA/M) and the Government of Sudan represented by the National Congress Party ending the Second Sudanese Civil War. The conflict was Africa's longest running civil war.
