Andries Wilhelmus Jacobus Pretorius (27 November 1798 – 23 July 1853) was a leader of the Boers who was instrumental in the creation of the Transvaal Republic, as well as the earlier but short-lived Natalia Republic, in present-day South Africa.
Early life and background 
Pretorius received his education at home and although a school education wasn't a priority on the eastern frontier of the Cape Colony, he was schooled enough to read the Bible and put his thoughts down on paper. Andries Pretorius had five children, the oldest, Marthinus Wessel Pretorius, later became the first President of the South African Republic.
Pretorius descended from the line of the earliest Dutch settlers in the Cape Colony. He belonged to the fifth generation of the progenitor, Johannes Pretorius  son of Reverend Wessel Scout of the Netherlands. Scout in his time as a theology student at the University of Leiden changed his name to the Latin form and therefore became Wesselius Praetorius (later Pretorius).
In September 1836, after the up company of Gerrit Maritz left Graaff-Reinet to go northwards, those that stayed behind including Pretorius began to strongly consider leaving the Cape Colony. He left his home in October 1837 on a scouting expedition to visit the Trekkers. Eventually Pretorius would leave the Cape Colony permanently. He abandoned his trek toward the Modderrivier and made haste to the Klein-Tugela river in Natal when he was summoned to lead the Voortrekkers who were there leaderless; Gerrit Maritz died of illness and Andries Potgieter left Natal moving deeper inland. Piet Retief and Piet Uys were murdered in February 1838 along with their men under command of the Zulu king Dingane. They were invited under false pretenses, during a negotiations visit, along with 70 men with boys among them and with 30 servants to enter the Zulu kraal Mgungundlovu unarmed.
Pretorius arrived at the desperate Trekkers' main camp on the 22nd of November 1838. Pretorius' diligence and thorough action immediately instilled confidence and he was appointed chief commander of the punitive commando against Dingane.
Pretorius lead 470 men with 64 wagons into Dingane's territory and on the dawn of 16 December 1838, next to the Ncome river, they would achieve victory over an attacking army of 10,000 to 15,000 Zulu warriors. The Voortrekkers fought with muzzle-loading rifles and made use of two small cannons. The Zulus sustained losses of an estimated 3,000 warriors in what became known as the Battle of Blood River. The Boers sustained no casualties. Three men were injured including Andries Pretorius who was injured on his hand by an Assegai.
After the battle Pretorius made an agreement with Dingane's brother Mpande which forced Dingane and those loyal to him into exile.
The Boers believe that God granted them victory and thus promised that they and their descendants would commemorate the day of the battle as a day of rest. Boers memorialized it as "Dingane's Day" until 1910. It was renamed "Day of the Vow", later "Day of the Covenant", and made a public holiday by the first South African government. After the fall of apartheid in 1994, the new government kept the day as a public holiday as an act of conciliation to Boers, but renamed it "Day of Reconciliation".
In January 1840, Pretorius with a commando of 400 burghers, helped Mpande in his revolt against his half-brother Dingane. He was also the leader of the Natal Boers in their opposition to the British. In 1842, Pretorius besieged the small British garrison at Durban, but retreated to Pietermaritzburg on the arrival of reinforcements under Colonel Josias Cloete. Afterward, he exerted his influence with the Boers to reach a peaceful solution with the British, who annexed Natalia.
Remaining in Natal as a British subject, in 1847 Pretorius was chosen by the Boer farmers to present their grievances to the governor of Cape Colony. They were concerned about the continuous migration of natives who were assigned locations to the detriment of Boer land claims. Pretorius went to Grahamstown to seek an audience with the governor, Sir Henry Pottinger, but he refused to see Pretorius or receive any communication from him. Pretorius returned to Natal determined to abandon his farm and move beyond the British dominions.
With a considerable following, he was preparing to cross the Drakensberg when Sir Harry Smith, newly appointed governor of the Cape, reached the emigrants' camp on the Tugela River in January 1848. Smith promised the farmers protection from the natives and persuaded many of the party to remain. Pretorius departed, and, on the proclamation of British sovereignty up to the Vaal River, fixed his residence in the Magaliesberg, north of that river. He was chosen by the burghers living on both banks of the Vaal as their commandant-general. At the request of the Boers at Winburg, Pretorius crossed the Vaal in July and led the anti-British party in their "war of freedom", occupying Bloemfontein on 20 July. In August, he was defeated at Boomplaats by Smith and retreated to the north of the Vaal. He became leader of one of the largest of the parties into which the Transvaal Boers were divided, and commandant-general of Potchefstroom and Rustenburg, his principal rival being Commandant-General A. H. Potgieter.
In 1851, Boer malcontents in the Orange River Sovereignty and the Basotho chief Moshoeshoe I asked Pretorius to come to their aid. He announced his intention of crossing the Vaal to "restore order" in the Sovereignty. His goal was to obtain an acknowledgment of the independence of the Transvaal Boers from the British. Having decided on a policy of abandonment, the British cabinet entertained his proposal. The government withdrew its reward of 2000 pounds, which had been offered for his capture after the Boomplaats battle. Pretorius met the British commissioners near the Sand River. On 17 January 1852 they concluded the convention by which the independence of the Transvaal Boers was recognized by Britain.
Pretorius recrossed the Vaal River, and on 16 March he reconciled with Potgieter at Rustenburg. The followers of both leaders approved the convention, although the Potgieter party was not represented. In the same year, Pretorius paid a visit to Durban with the object of opening up trade between Natal and the new republic. In 1852, he also attempted to close the road to the interior through Bechuanaland and sent a commando to the western border against Sechele.
Pretorius died at his home at Magaliesberg in July 1853. He is described by Theal as "the ablest leader and most perfect representative of the Emigrant Farmers." In 1855, a new district and a new town were formed out of the Potchefstroom and Rustenburg districts by his son, Marthinus Wessel Pretorius, who named them Pretoria in honour of the late commandant-general. Marthinus Wessel Pretorius was the first president of the Transvaal Republic.
