Answer
Hegemony is a stratified social order in which subordinates comply with domination by internalizing their rulers' values and accepting the "naturalness" of domination.
Explanation:
A hegemony, like the answer says, describes a situation where a group exerts dominance over another group. This can happen in political, business or financial circles. This dominance is portrayed as the natural order of things.
The dominant group in a hegemony portrays its values and ideals as being right and those under their dominion comply or risk seeing their different opinions as threats that would have to be dealt with.
