Final answer:
South Africa's situation during the Age of Imperialism was unique because the Dutch settlers established it as a settler colony and focused on removing the natives rather than subjugating them. Thousands of Europeans migrated to South Africa and worked alongside natives in the colonial administration.
Step-by-step explanation:
South Africa's situation during the Age of Imperialism could be seen as "unique" because the Dutch settlers established it as a "settler colony" rather than just a trading post. Unlike other European powers, the Dutch were interested in forming a community of farmers and removing the natives rather than subjugating them. Thousands of Europeans migrated to South Africa attracted by the climate and arable land, and natives and whites worked side-by-side in the colonial administration.
