Answer:
The belief that one's own culture is superior to other cultures is known as ethnocentrism.
Explanation:
Ethnocentrism is the belief that one's own culture is the correct way of life, or the only one; it is vewing other cultures through the eyes of one's own, and comparing and criticizing them. In a few words, it is the belief the one's own culture is superior to others. Ethnocentrism plays an important rol on attitudes like racism and xenophobia, that translate into actions carried on to impose one's culture to the rest of the world and to discriminate and segregate.
When carried on by governments and whole groups of population, ethnocentrism has led to historic episodes such as nazism.
