Are laws governments make in order to protect the rights of minorities from discrimination. environmental protection laws civil rights laws economic regulation laws laws authorizing homeland security measures

I believe the answer is civil rights Laws.
Civil Rights law banned different treatment for individuals based on their race, sex, origin, and religion.
The law was initially made to make sure that minorities obtained equal treatment in the workforce following the Racial Segregation that created by jim Crow's law.

The   civil  right  law  are  governments  laws  that  make  in  order   to  protect   the  right  of  minorities   from  discrimination.  The  civil  right  of  1964  in  united  state  outlaws  discrimination  based   on  race, religion,sex  or  national  origins. It  also  prohibited  unequal  application  of   voters   registration,racial  segregation  in  schools,employment  and  public  accommodation.
