What were some of the basic rights that a slave did not have?

Assuming that you mean slaves in America, they were deprived of many rights including these:

Could not vote

Could not marry without their master's permission. This was often complicated

when the couple belonged to two different masters. The children would be

divided accordingly.

Most slaves were denied an education

Could be legally killed by their masters

When a state's population was determined to calculate the amount of representatives the state got, a slave would only count as 3/5 of a person.

A pretty degrading law

Those were the main rights and privileges that American slaves didn't have.

There are a few other minor ones too.
