Soshangane kaZikode (c. 1780 – c. 1858), born Soshangane Nxumalo, was the founder and self-crowned king of the Gaza Empire, which at the height of its power stretched over modern-day southern Mozambique and all the way to the Limpopo River. Soshangane ruled over the Gaza state from 1825 until his death in 1858. Soshangane was also known by the name of Manukosi, and his troops where responsible for the massacre of the Janse van Rensburg trek.
Soshangane was born in ca 1780 in modern-day KwaNongoma, KwaZulu to Zikode kaGasa, a chief the junior branch (iKohlo) of the Ndwandwe. His younger brother was Mhlabawadabuka. The Gasa occupied the Mkuze region around the eTshaneni mountain (Ghost Mountain) whilst the senior house under Zwide lived in Magudu near the Pongola Valley. Around the same time that the Ndwandwe were growing in military power, Zwide ascended to the Ndwandwe-Nxumalo throne following the death of his father Langa KaXaba.
It was at this time that Zwide sought to expand his borders, and in 1818 he destroyed the power of the Mthethwa Kingdom, after he had their paramount chief Dingiswayo KaJobe killed. Zwide and his Ndwandwe forces then destroyed and overran the neighbouring Khumalo Kingdom and executed their chief Mashobana KaMangete with the help of Queen Ntombazi, a witch doctor and Langa kaXaba's wife. Mashobana's son and heir Mzilikazi escaped from the Ndwandwe-Nxumalo and sought refuge with Shaka, who had reformed the remnant Mthethwa clan under his rule. The Ndwandwe and Zulu would clash for the first time at the Battle of Gqokli Hill in which Zwide and his heir Nomahlanjana were commanders of the Ndwandwe forces, whilst neither side emerged victorious, these two military powers would soon clash again. In 1820, with Soshangane kaGasa as the commanding general of the Ndwandwe army under King Zwide, the Ndwandwe forces were attacked by the Zulu forces whilst crossing the Mhlatuze River, scattered and confused the Zulu inflicted a resounding defeat on the Ndwandwe, however losses were heavy on both sides. Following this defeat, Soshangane led a remnant of the army and of the Ndwandwe people northwards and away from Shaka's Zulu hegemony.
