Your question puzzles me in several ways.
1. "was" -- to what period(s) of time is this question referring?
2. "ethnic minorities" is a relative term, depending on where a person is in the world. In most of India, anyone other than a Hindu is in the minority, no matter what his/her ethnic background is. In the US, people can be considered part of an ethnic minority if they live in Minnesota (for example) but not in Southern California.
Please define your terms better. You won't write a decent response for this assignment unless you can clarify what this is actually asking.
