Born Jan. 20, 1834, in Oudtshoorn, Cape Province; died Mar. 28, 1900, in Pretoria. Political and military leader of the Republic of Transvaal.
Joubert became commander in chief of the Boer Army in 1880. During the Anglo-Boer War of 1880–81 he won a victory at Majuba; in January 1896 he defeated the British detachment of L. Jameson that had invaded the Transvaal. Joubert opposed President P. Kruger and advocated concessions to Great Britain. Elected vice-president in 1898, Joubert successfully led combat operations at the beginning of the Anglo-Boer War of 189–1902, but a severe illness compelled him to turn over the command to General L. Botha.
