The period Jacksonian Democracy

To what extent did the period Jacksonian Democracy initiate threats to the rights of minority groups in America?
In your answer be sure to address: 1. John C. Calhoun’s concept of the concurrent majority as a way to protect the minority rights of southern slaveholders. 2. The Cherokee understanding of their national and individual rights, and the ways they were threatened by the majority. 3. Attempts by northern free blacks to retain their right to vote in the face of majority pressure.
