In 1924, there was a change in government and General JBM Hertzog took over and with this came a new Minister of Lands, P Grobler, a staunch Afrikaner and a 1914-rebel. It seems that he took a firmer stand with the landowners, and they accepted suitable unoccupied land in the Transvaal in exchange for the land was to be incorporated into the Park, at the end of 1925.
It might be that the landowners realised that this new government, with its lack of sympathy for Johannesburg business interests, would negotiate no further and that expropriation was a reality.
Afrikaner Nationalism started to rise in the 1920's and many people saw the establishment of a national park as the realisation of 'Paul Kruger's dreams'. Deneys Reitz, who knew President Kruger and fought in the Boer War, advocated this and stated that it was a national duty to preserve the landscape 'just as the Voortrekkers saw it'.
Some English-speaking protectionists made use of Afrikaner sentiment to lobby for the creation of a national park. Even the use of Paul Kruger's name was a political issue used to rally support. James Stevenson-Hamilton publicly stated that 'Kruger National Park was an excellent name'. Other names suggested were South African National Park and National Milner Park.
The move for a national park gained massive support. On 31 May 1926, the Minister of Lands, P Grobler, asked parliament to pass the Act on National Parks (Act 46 of 1926), the leader of the opposition, General Jan Smuts, seconded the motion.
In a show of solidarity, both Houses of Parliament passed the National Parks Act unanimously in May and June 1926. The Kruger National Park had at last come into being.
