Final answer:
Rinderpest harmed the colonized people of Africa through economic stagnation and the spread of infectious diseases.
Step-by-step explanation:
Rinderpest, a cattle disease brought by colonizers to Africa, had several harmful impacts on the colonized people. One of the main ways it harmed the colonized people of Africa was through economic stagnation. When rinderpest struck, it killed the domestic cattle, which were crucial for agriculture and transportation. This caused a decline in agricultural productivity and made it harder for the people to grow enough food. Additionally, rinderpest led to the spread of infectious diseases as the mosquitoes that previously fed on cattle turned to biting humans and spreading malaria.
