In 1983, Garang went to
Bor and southern government soldiers in Battalion 105 who were resisting being rotated to posts in the north. Although he was not among the officers in the Southern command arranging for the defection of Battalion 105 to the anti government rebels, he was supporting the revolution. When the 105 Battalion attacked Sudanese army in Bor on 16 May 1983 under the command of Major
Kerubino Kuanyin Bol, who was the leader of the budding movement which launched an impromptu attack, Garang rode by an alternative route to join them in the rebel stronghold in Ethiopia. Major Kerubino Kuanyin Bol and William Nyuon Bany Machar led Battalion 105 and 107 in Bor and Ayot, respectively. As a major, Kerubino coalesced with William to organize a revolt and opened routes to Ethiopian plains. By the end of July,
Sudan People's Liberation Army/Movement (SPLA) had brought over 3000 soldiers into the newly created
Sudan People's Liberation Army/Movement (SPLA/M), which was opposed to military rule and Islamic dominance of the country, and encouraged other army garrisons to mutiny against the
Islamic law imposed on the country by the government.
William Nyuon Bany and
Kerubino Kwanyin Bol were both founding members of SPLA. Bany was appointed the 3rd high-ranking Commander after Bol. This action marked the commonly agreed upon beginning of the
Second Sudanese Civil War, which resulted in one and a half million deaths over twenty years of conflict. Although Garang was Christian and most of southern Sudan is non-Muslim (mostly
animist), he did not initially focus on the religious aspects of the war. Garang was a strong advocate for national unity: minorities together formed a majority and, therefore should rule. Together, Garang believed, they could replace President
Omar al-Bashir with a government made up of representatives from “all tribes and religions in Sudan." His first real effort for the cause, under his command, occurred in July 1985 with the SPLA’s incursion into Kordofan. The SPLA gained the backing of Libya, Uganda, and Ethiopia. Garang and his army controlled a large part of the southern regions of the country, named "New Sudan". He claimed his troops' courage came from "the conviction that we are fighting a just cause. That is something North Sudan and its people don't have." Critics suggested financial motivations to his rebellion, noting that much of Sudan's
oil wealth lies in the south of the country. Shortly after, there were leadership misunderstandings between Garang and senior SPLA commanders,
Riek Machar and
Lam Akol in August 1991. The splinter group led by Machar and Akol was named the
SPLA-Nasir. which enraged civilians and exposed the deep ethnic divides within the SPLA. The Southern Sudanese communities became more divided than ever before in their history. These organic divides among the Southern Sudanese communities were exacerbated by the deliberate "divide and rule" policies instituted by the regimes in Khartoum, in order to maintain their power over the Southern Sudanese peoples. SPLA-Nasir accused Garang of ruling by force, in a "dictatorial reign of terror"; but ethnic rivalry seemed to have a part, with the Nasir faction mainly composed of
Nuer, and Garang's supporters mainly
Dinka people. Months of fighting between the two factions left thousands dead in early 1992. The SPLA-Nasir also raised the idea of an independent south (whereas Garang wanted unity). and later joined forces with Bol to form
SPLA-United, Sudanese People's Liberation Army-United. Garang had refused to participate in the 1985 interim government or the 1986 elections, remaining a rebel leader. However, the SPLA and government signed a peace agreement on January 9, 2005, in
Nairobi, in Kenya. On July 9, 2005, he was sworn in as the First-Vice-President – the second most powerful person in the country – following a ceremony in which he and President
Omar al-Bashir signed a power-sharing constitution. Simultaneously, he became the premier in southern Sudan. This administration had limited autonomy for six years, at the end of which there would be a scheduled referendum regarding secession. No Christian or southerner had ever held such a high government post. Commenting after this ceremony, Garang stated, "I congratulate the Sudanese people, this is not my peace or the peace of al-Bashir, it is the peace of the Sudanese people." In the Hillcrest Hotel in
Nairobi on New Year's Day 2003, there was a meeting between the SPLA and the
Fur people. Garang asked two associates of
Abdul Wahid al Nur (who later formed the
Sudan Liberation Movement) to declare that the
Fur people were with the SPLA – they refused. Under his leadership, the SPLA was accused of human rights abuses. U.S. President
George W. Bush, who supported South Sudanese independence, especially considered Garang to be a promising leader and called him a "partner in peace." Bush highlighted Garang's Christian faith, and even connected him to support at evangelical churches in his hometown of
Midland, Texas. Garang effectively used radio to advance his cause. ==Death==
