Answer: The living conditions of the people in the Middle Ages were poor.
Explanation:
The feudal system, which was organized so that the largest number belonged to the lowest social class, caused the serfs a terrible situation in society. Living conditions for most Middle Ages (except kings, landowners, and church leaders) were difficult. Primarily people were deficient in lack of food. Through the feudal system, most received as much as was enough to survive. Hygienic conditions were terrible; there was no sewage infrastructure, so an unbearable stench spread from most cities. In such circumstances, various epidemics broke out that decimated the European population.
African Americans were not the only people to demand equal rights in the 1960s. The message of Dr. Martin Luther King inspired other groups to publicize and seek their own civil rights—chiefly women, Hispanic Americans, and Native Americans.
