(Cape Town is the legislative capital and Bloemfontein the judicial capital). Pretoria is the central part of the City of Tshwane Metropolitan Municipality which was formed by the amalgamation of several former local authorities including Centurion and Soshanguve). There have been proposals to change the name of Pretoria itself to Tshwane, and the proposed name change has caused some controversy.
Pretoria is named after the Voortrekker leader Andries Pretorius, and within South Africa is popularly known as the Jacaranda City due to the thousands of Jacaranda trees planted in its streets, parks and gardens.
Pretoria was founded in 1855 by Marthinus Pretorius, a leader of the Voortrekkers, who named it after his father Andries Pretorius and chose a spot on the banks of the "Apies rivier" (Afrikaans for "Monkeys river") to be the new capital of the South African Republic (ZAR). The elder Pretorius had become a national hero of the Voortrekkers after his victory over the Dingane and the Zulus in the Battle of Blood River. The elder Pretorius also negotiated the Sand River Convention (1852), in which Britain acknowledged the independence of the Transvaal. It became the capital of the South African Republic (ZAR) on 1 May 1860.
