The Umma Party (UP)
During the last period of parliamentary democracy, the Umma Party was the largest in the country, and its leader, Sadiq al Mahdi served as prime minister in all coalition governments between 1986 and 1989. Originally founded in 1945, the Umma was the political organization of the Islamic Ansar movement. Its supporters followed the strict teachings of the Mahdi, who ruled Sudan in the 1880s. Although the Ansar were found throughout Sudan, most lived in rural areas of western Darfur and Kurdufan. Since Sudan became independent in 1956, the Umma Party has experienced alternating periods of political prominence and persecution. Sadiq al Mahdi became head of the Umma and spiritual leader of the Ansar in 1970, following clashes with the Nimeiri government, during which about 3,000 Ansar were killed. Following a brief reconciliation with Nimeiri in the mid-1970s, Sadiq al Mahdi was imprisoned for his opposition to the government’s foreign and domestic policies, including his 1983 denunciation of the September Laws as being un-Islamic.

Despite Sadiq al Mahdi’s criticisms of Nimeiri’s efforts to exploit religious sentiments, the Umma was an Islamic party dedicated to achieving its own Muslim political agenda for Sudan. Sadiq al Mahdi had never objected to the sharia becoming the law of the land, but rather to the “un-Islamic” manner Nimeiri had used to implement the sharia through the September Laws. Thus, when Sadiq al Mahdi became prime minister in 1986, he was loath to become the leader who abolished the sharia in Sudan. Failing to appreciate the reasons for non-Muslim antipathy toward the sharia, Sadiq al Mahdi cooperated with his brother-in-law, NIF leader Turabi, to draft Islamic legal codes for the country. By the time Sadiq al Mahdi realized that ending the civil war and retaining the sharia were incompatible political goals, public confidence in his government had dissipated, setting the stage for military intervention. Following the June 1989 coup, Sadiq al Mahdi was arrested and kept in solitary confinement for several months. He was not released from prison until early 1991. Sadiq al Mahdi indicated approval of political positions adopted by the Umma Party during his detention, including joining with the SPLM and northern political parties in the National Democratic Alliance opposition grouping.

The Democratic Unionist Party (DUP)
The Democratic Unionist Party (DUP) was similarly based on a religious order, the Khatmiyyah organization. Ever since the Khatmiyyah opposed the Mahdist movement in the 1880s, it has been a rival of the Ansar. Although the Khatmiyyah was more broadly based than the Ansar, it was generally less effective politically. Historically, the DUP and its predecessors were plagued by factionalism, stemming largely from the differing perspectives of secular-minded professionals in the party and the more traditional religious values of their Khatmiyyah supporters. The DUP leader and hereditary Khatmiyyah spiritual guide since 1968, Muhammad Uthman al Mirghani, tried to keep these tensions in check by avoiding firm stances on controversial political issues. In particular, he refrained from public criticism of Nimeiri’s September Laws so as not to alienate Khatmiyyah followers who approved of implementing the sharia. In the 1986 parliamentary elections, the DUP won the second largest number of seats and agreed to participate in Sadiq al Mahdi’s coalition government. Like Sadiq al Mahdi, Mirghani felt uneasy about abrogating the sharia, as demanded by the SPLM, and supported the idea that the September Laws could be revised to expunge the “un- Islamic” content added by Nimeiri.

By late 1988, however, other DUP leaders had persuaded Mirghani that the Islamic law issue was the main obstacle to a peaceful resolution of the civil war. Mirghani himself became convinced that the war posed a more serious danger to Sudan than did any compromise over the sharia. It was this attitude that prompted him to meet with Garang in Ethiopia where he negotiated a cease-fire agreement based on a commitment to abolish the September Laws. During the next six months leading up to the June 1989 coup, Mirghani worked to build support for the agreement, and in the process emerged as the most important Muslim religious figure to advocate concessions on the implementation of the sharia. Following the coup, Mirghani fled into exile and he has remained in Egypt. Since 1989, the RCC-NS has attempted to exploit DUP factionalism by coopting party officials who contested Mirghani’s leadership, but these efforts failed to weaken the DUP as an opposition group.

The National Islamic Front (NIF)
The Muslim Brotherhood, which originated in Egypt, has been active in Sudan since its formation there in 1949. It emerged from Muslim student groups that first began organizing in the universities during the 1940s, and its main support base has remained the college educated. The Muslim Brotherhood’s objective in Sudan has been to institutionalize Islamic law throughout the country. Hassan Abdallah al Turabi, former dean of the School of Law at the University of Khartoum, had been the Muslim Brotherhood’s secretary general since 1964. He began working with Nimeiri in the mid-1970s, and, as his attorney general in 1983, played a key role in the controversial introduction of the sharia. After the overthrow of Nimeiri, Turabi was instrumental in setting up the NIF, a Brotherhood-dominated organization that included several other small Islamic parties. Following the 1989 coup, the RCC-NS arrested Turabi, as well as the leaders of other political parties, and held him in solitary confinement for several months. Nevertheless, this action failed to dispel a pervasive belief in Sudan that Turabi and the NIF actively collaborated with the RCC-NS. NIF influence within the government was evident in its policies and in the presence of several NIF members in the cabinet.

Sudanese People’s Liberation Movement (SPLM)
The SPLA was formed in 1983 when Lieutenant Colonel John Garang of the SPAF was sent to quell a mutiny in Bor of 500 southern troops who were resisting orders to be rotated to the north. Instead of ending the mutiny, Garang encouraged mutinies in other garrisons and set himself at the head of the rebellion against the Khartoum government. Garang, a Dinka born into a Christian family, had studied at Grinnell College, Iowa, and later returned to the United States to take a company commanders’ course at Fort Benning, Georgia, and again to earn advanced economics degrees at Iowa State University.

By 1986 the SPLA was estimated to have 12,500 adherents organized into twelve battalions and equipped with small arms and a few mortars. By 1989 the SPLA’s strength had reached 20,000 to 30,000; by 1991 it was estimated at 50,000 to 60,000. Many members of the SPLA continued their civilian occupations, serving in individual campaigns when called upon. At least forty battalions had been formed, bearing such names as Tiger, Crocodile, Fire, Nile, Kalishnikov, Bee, Eagle, and Hippo.

The Republican Brothers
A small but influential religious party in the early 1980s was the Republican Brothers. A Sufi shaykh, Mahmud Muhammad Taha, founded the Republican Brothers in the 1950s as an Islamic reform movement stressing the qualities of tolerance, justice, and mercy. Taha came to prominence in 1983 when he opposed Nimeiri’s implementation of the sharia as being contrary to the essence of Islam. He was arrested and subsequently executed for heresy in January 1985. The execution of such a widely revered religious figure–Taha was seventy-six–aroused considerable revulsion in Sudan and was one of the factors that helped precipitate the coup against Nimeiri. Although the Republican Brothers survived the loss of its leader and participated in the political process during the parliamentary period, it has not been politically active since 1989.

The Sudanese Communist Party (SCP)
The SCP was formed in 1944 and early established a strong support base in universities and labor unions. Although relatively small, the SCP had become one of the country’s best organized political parties by 1956 when Sudan obtained its independence. The SCP also was one of the few parties that recruited members in the south. The various religiously affiliated parties opposed the SCP, and, consequently, the progression of civilian and military governments alternately banned and courted the party until 1971, when Nimeiri accused the SCP of complicity in an abortive military coup. Nimeiri ordered the arrest of hundreds of SCP members, and several leaders, including the secretary general, were convicted of treason in hastily arranged trials and summarily executed. These harsh measures effectively crippled the SCP for many years.

Following Nimeiri’s overthrow, the SCP began reorganizing, and it won three seats in the 1986 parliamentary elections. Since the June 1989 coup, the SCP has emerged as one of the Bashir government’s most effective internal opponents, largely through fairly regular publication and circulation of its underground newspaper, Al Midan. In November 1990, Babikr at Tijani at Tayib, secretary general of the banned SCP, managed to escape from house arrest and flee to Ethiopia.

The Baath Party
The Baath Party of Sudan was relatively small and sided with the Baath Party of Iraq in the major schism that divided this pan-Arab party into pro-Iraqi and pro-Syrian factions. The Baath remained committed to unifying Sudan with either Egypt or Libya as an initial step in the creation of a single nation encompassing all Arabic-speaking countries; however, the Baath’s ideological reservations about the existing regimes in those two countries precluded active political support for this goal. The Nimeiri and Bashir governments alternately tolerated and persecuted the Baath. The RCC-NS, for example, arrested more than forty-five Baathists during the summer of 1990. Restrictions against the Baath were eased at the end of year, presumably because Sudan supported Iraq during the Persian Gulf War.
