 Skukuza was a proud home of the Tsonga people until 1905, when they were forcibly removed by the Colonial Government to make way for South Africa's largest game reserve.
 The Tsonga people not only occupied Skukuza but the entire area east of the modern town of Hazyview was the land of the Tsonga, from Phabeni gate, Kruger gate up until Skukuza it was a land belonging to the Tsonga people which was a land of some distance stretching for more than 50km east of the modern town of Hazyview.
 The evicted Tsonga were resettled in villages around Hazyview, such as Hoxani, Cunningmore, Mkhuhlu, where there was already a problem of overcrowding by large Tsonga speaking communities.
 The Tsonga people were finally removed from Skukuza in 1926 and the entire Park completely in 1960.
