Soshangane then began to carve out a Nguni empire of conquest known as the Gaza Empire (or Gasa), named after his grandfather Gasa KaLanga, which would later significantly expand to cover areas over present day southern Mozambique, and parts of the Limpopo River around Mandlakazi. The rise of the Gaza Kingdom was based primarily on military conquests, particularly of the Vahlengwe, Vadjonga, Vahlave and Ndau peoples, who would be absorbed into the Nguni Gaza Kingdom. Soshangane then began a campaign to create a new language and culture named after himself.
