How did the introduction of quinine affect colonial policy?

The introduction of quinine, an effective treatment for malaria, significantly impacted colonial policy by enabling European powers to expand their territories in tropical regions previously considered inhospitable due to the disease. With malaria managed, colonizers were able to establish and maintain settlements, facilitate trade, and exploit resources in Africa and other regions. This led to increased colonization efforts, deeper economic exploitation, and the establishment of more extensive administrative structures to govern these areas. Ultimately, quinine played a crucial role in shaping the dynamics of imperial expansion and colonial governance.
