Who are Ham's descendants?
Ham was the son of Noah who,
when his father lay drunk and naked in his tent, did not pay the necessary respect to Noah. The other two sons of Noah, Shem and Japheth, walked backwards with a robe while they kept their faces turned away so as not to see him naked, and covered Noah with the robe.
When Noah was sober again, he placed a curse on Canaan, the son of Ham and said Canaan would be a slave to Shem
and Japhet. Read the sad story in Genesis 9:20-27.
It is difficult to say which nations are the descendants of Ham today. In Genesis 10:6-20 we find a genealogical list of some of Ham's descendents and the places where they lived.
Please note that Noah cursed
the son of Ham, Canaan. The descendents of Canaan dwelt in Canaan in the time of Joshua and were either destroyed or subjected to Israel. So the prophecy of Noah was fulfilled.
When Christ died for the sins of the world he took away any curse that might have been on any nation and set everyone free who believes in Him. No nation or nations are today under any curse of God.
