The current flag of Sudan was adopted on 20 May 1970 and consists of a horizontal red-white-black tricolour with a green triangle at the hoist. The flag is based on the Arab Liberation Flag of the Egyptian Revolution of 1952, as are the flags of Egypt, Iraq, Syria, Yemen, and Palestine and formerly of the United Arab Republic, North Yemen, South Yemen, and the Libyan Arab Republic.
The National Congress Party was a major political party that dominated domestic politics in Sudan from its foundation until the Sudanese Revolution.
The First Sudanese Civil War was a conflict from 1955 to 1972 between the northern part of Sudan and the southern Sudan region that demanded representation and more regional autonomy. The war was divided into four major stages: initial guerrilla warfare, the creation of the Anyanya insurgency, political strife within the government and establishment of the South Sudan Liberation Movement. Around a million people died over the course of the nearly 17-year long war.
The Anyanya were a southern Sudanese separatist rebel army formed during the First Sudanese Civil War (1955–1972). A separate movement that rose during the Second Sudanese Civil War were, in turn, called Anyanya II. Anyanya means "snake venom" in the Ma'di language.
The Sudan People's Liberation Movement is a political party in South Sudan. It was initially founded as the political wing of the Sudan People's Liberation Army in 1983. On January 9, 2005 the SPLA, the SPLM and the Government of Sudan signed the Comprehensive Peace Agreement, ending the civil war. SPLM then obtained representation in the Government of Sudan, and was the main constituent of the Government of the then semi-autonomous Southern Sudan. When South Sudan became a sovereign state on 9 July 2011, SPLM became the ruling party of the new republic. SPLM branches in Sudan separated themselves from SPLM, forming the Sudan People's Liberation Movement–North. Further factionalism appeared as a result of the 2013–2014 South Sudanese Civil War, with President Salva Kiir leading the SPLM-Juba and former Vice President Riek Machar leading the Sudan People's Liberation Movement-in-Opposition.
The Republic of the Sudan was established as an independent sovereign state upon the termination of the condominium of Anglo-Egyptian Sudan, over which sovereignty had been vested jointly in Egypt and the United Kingdom. On December 19, 1955, the Sudanese parliament, under Ismail al-Azhari's leadership, unanimously adopted a declaration of independence that became effective on January 1, 1956. During the early years of the Republic, despite political divisions, a parliamentary system was established with a five member Supreme Commission as head of state. In 1958, after a military coup, General Ibrahim Abboud was installed as president. The Republic was disestablished when a coup led by Colonel Gaafar Nimeiry founded the Democratic Republic of Sudan in 1969.
On 25 May 1969, several young officers calling themselves the Free Officers Movement seized power in Sudan in a coup d'état and started the Nimeiry era, also called the May Regime, in the history of Sudan. At the conspiracy's core were nine officers led by Colonel Gaafar Nimeiry, who had been implicated in plots against the Abboud regime. Nimeiry's coup preempted plots by other groups, most of which involved army factions supported by the Sudanese Communist Party (SCP), Arab nationalists, or conservative religious groups. He justified the coup on the grounds that civilian politicians had paralyzed the decision-making process, had failed to deal with the country's economic and regional problems, and had left Sudan without a permanent constitution.
The Sudanese Communist Party is a communist party in Sudan. Founded in 1946, it was a major force in Sudanese politics in the early post-independence years, and was one of the two most influential communist parties in the Arab world, the other being the Iraqi Communist Party.
Anyanya II is the name taken in 1978 by a group of the 64 tribes of South Sudan dissidents who took up arms in All of Sudan. The name implies continuity with the Anyanya, or Anya-Nya, movement of the First Sudanese Civil War (1955-1972).
The flag of South Sudan was adopted following the signing of the Comprehensive Peace Agreement that ended the Second Sudanese Civil War. A different version of the flag was previously used as the flag of the Sudan People's Liberation Movement. The flag of South Sudan predates the country, as the flag was adopted in 2005, while the country became independent in 2011.
The South Sudan People's Defence Forces (SSPDF), formerly the Sudan People's Liberation Army (SPLA), is the army of the Republic of South Sudan. The SPLA was founded as a guerrilla movement against the government of Sudan in 1983 and was a key participant of the Second Sudanese Civil War, led by John Garang. After Garang's death in 2005, Salva Kiir was named the SPLA's new Commander-in-Chief. As of 2010, the SPLA was divided into divisions of 10,000–14,000 soldiers.
The Sudan African National Union is a political party formed in 1963 by Saturnino Ohure and William Deng Nhial in Uganda. In the late 1960s, the party contested elections in Sudan seeking autonomy for southern Sudan within a federal structure. The exile branch of the party meanwhile supported full independence. A party with this name was represented in the Southern Sudan legislature in 2008.
Kerubino Kuanyin Bol was a Sudanese rebel leader who was one of the founders of the Sudan People's Liberation Movement (SPLM) and one of the leaders of the Sudan People's Liberation Army (SPLA) during the Second Sudanese Civil War and was said to have fired the first shot in the conflict.
Joseph Oduho Haworu was a leading politician from southern Sudan who was active in the struggle for independence and a founding member of the Sudan People's Liberation Movement (SPLM).
William Deng Nhial was the political leader of the Sudan African National Union (SANU), from 1962 to 1968. He was elected unopposed. He was one of founders of the military wing of the Anyanya fighting for the independence of southern Sudan. He was ambushed and killed by Sudanese Armed Forces (SAF) on 9 May 1968 at Cueibet, on his way from Rumbek to Tonj. The Sudanese government denied having authorised his assassination. Although no investigation was conducted, eyewitnesses at Cueibet village and an SANU investigation committee confirmed the SAF's part in his death.
Ezboni Mondiri Gwanza was a politician in Southern Sudan. He was one of the founders of the Southern Sudan Federal Party (SSFP) in 1957, which competed in the Sudanese parliamentary election in 1958. Later he was active in secessionist movements.
Aggrey Jaden Ladu was a South Sudanese politician.
Gordon Muortat Mayen Maborjok (1922–2008) was a South Sudanese veteran politician and an advocate for the rights and freedom of the South Sudanese people. He was the President of the Nile Provisional Government (NPG) which led the Anyanya; Southern Sudan's first armed resistance to Khartoum which started in 1955.
