Did the ancient Egyptians really marry their siblings and children?

Here we see the entrance to at ancient Egyptian temple at Abu Simbel. There are four giant seated pharaohs, two on either side of the entrance.

It's often said that ancient Egyptian royalty married within the family, with pharaohs marrying siblings and sometimes even children. But is there any truth to the claim?

The answer is yes: People in ancient Egypt — both royal and nonroyal — married their relatives, but the details vary according to the time period and class.
