Why were the rights of enslaved people considered unusual for that time period?

The reason was that people in the past considered slaves less than human. This can be seen in the 3/5ths compromise where a slave wasnt values equally to a white person.

Explanation:

Between racism and a fale belief that a race was superior to another giving rights to slaves was uncommon since as stated they were seen as less than human and hence not given the bare human rights everyone deserves

the three-fifths compromise was proposed by james wilson and roger sherman, who were both delegates for the constitutional convention of 1787. however, the three-fifth compromise has its roots further back in history, dating back to the continental congress in 1783. the compromise was a result of the apportionment of taxes being related to land values.
