Introduction:
The white regime in South Africa refers to the apartheid government that was in power from 1948 to 1994. Apartheid was a system of racial segregation and discrimination enforced by the National Party, which predominantly consisted of white Afrikaners. The white regime eventually decided to change its policies due to various internal and external pressures.

Internal Pressures:
1. Social unrest and protests: The apartheid regime faced increasing resistance from black South Africans who were oppressed and marginalized under the discriminatory policies. Protests, strikes, and acts of civil disobedience became more frequent and widespread, putting pressure on the government to reconsider its stance.
2. Economic consequences: The apartheid regime faced economic isolation and sanctions from the international community, which had a detrimental impact on the country's economy. The government realized that maintaining the status quo would further exacerbate economic challenges.
3. Internal divisions within the white population: Not all white South Africans supported or benefited from apartheid. There were growing divisions within the white community, with some advocating for reform and an end to racial discrimination.

External Pressures:
1. International condemnation and sanctions: The apartheid regime faced increasing international criticism and condemnation for its discriminatory policies. Many countries imposed economic sanctions, sporting boycotts, and diplomatic isolation on South Africa, pressuring the government to change its policies.
2. Global anti-apartheid movement: The global anti-apartheid movement gained momentum in the 1970s and 1980s, with activists, organizations, and celebrities advocating for the end of apartheid. This movement raised awareness about the injustices of apartheid and put pressure on the white regime to reconsider its policies.
3. Changing geopolitical landscape: The end of the Cold War and the fall of communism had a significant impact on global politics. With the transition to a more democratic and inclusive world order, the apartheid regime became increasingly isolated and outdated.

Transition to Change:
Amid mounting pressures, the apartheid regime initiated a process of negotiations and reforms in the late 1980s and early 1990s. Key milestones in this transition included the release of Nelson Mandela from prison in 1990, the unbanning of political organizations, and the repeal of discriminatory laws. These steps eventually led to the democratic elections in 1994, marking the end of apartheid and the beginning of a new era for South Africa.

Conclusion:
The decision of the white regime to change its policies was driven by a combination of internal and external pressures. Social unrest, economic consequences, internal divisions, international condemnation, the global anti-apartheid movement, and the changing geopolitical landscape all played crucial roles in pushing the apartheid government towards reform and dismantling the discriminatory system.
