Then, in about 1500 B.C., a new, more technically advanced group of people arrived in the region. These people were known as the Aryans. The Aryans were a fair skinned people that used their technologies to conquer the peoples of the Indus River Valley.
Fair play is primarily not blaming others for anything that is wrong with us.
