Mortimer Wheeler believes that the Aryan Attack destroyed Harappan Culture. From the narrow street called Deadman-line, which was only 3 feet to 6 feet wide, in Mohenjo Daro, many scattered skeletons of men, women and children were discovered. Along with some skeletons, there were also weapons like axes and spears. It is based on these that Mortimer Wheeler came out with his theory of the Aryan Invasion. Wheeler maintained that these skeletons were of those killed in the Aryan attack.
Wheeler also tried to connect this evidence to the Rigveda in Rigveda there is a reference to ‘puranr’. Puram means fortress or citadel. The warlord of the Aryans is Lord Indran.
Indran is also called purandaran, which means one who destroys fortresses. It is based on this that some people, led by Mortimer Wheeler, argued that the Harappan culture was destroyed by the Aryans.
