History of Sudan association with the single largest political grouping, the [[National Umma Party Sudan|Umma Party]] (once led by a descendant of the Mahdi, [[Sadiq al Mahdi]]). Taking advantage of conditions resulting from Ottoman-Egyptian exploitation and maladministration, the Mahdi led a nationalist revolt culminating in the fall of [[Khartoum]] on 26 January 1885. The interim governor-general of the Sudan, the British Major-General [[Charles George Gordon]], and many of the fifty thousand inhabitants of Khartoum were massacred. The Mahdi died in June 1885. He was followed by [[Abdallahi ibn Muhammad]], known as the [[Caliph|Khalifa]], who began an expansion of Sudan's area into Ethiopia. Following
St. Matthew's Cathedral, Khartoum was built in 1847 to serve as the cathedral church. The Apostolic Vicariate was entrusted in 1872 to the Missionaries of the Sacred Heart, under Saint Daniel Comboni, who was apostolic vicar from 1872 until his death in 1881. The city was taken by the Mahdistas in 1885, who destroyed the church and all missions in the country. The war ended in 1898 with the Battle of Omdurman, and missionary work recommenced the following year. When the British built the modern city of Khartoum as capital of the Anglo-Egyptian Sudan, a new cathedral was constructed. It was completed in 1908
