The act was passed by Congress in February, 1875 and signed by
President Grant on March 1, 1875. It was declared unconstitutional by the US Supreme Court in 1883...
The Act guaranteed that everyone, regardless of race, color, or
previous condition of servitude, was entitled to the same treatment in
"public accommodations" (i.e. inns, public conveyances on land or
water, theaters, and other places of public amusement).
If found guilty, the lawbreaker could face a penalty anywhere from $500 to $1,000 and/or 30 days to 1 year in prison.
