Madhav Sadashiv Golwalkar (1906-1973) was a key ideologue of the Hindutva
movement, and RSS
sarsangchalak (supreme leader) from 1940. He equated national identity with racial identity, insisting on race rather than geography as the defining feature of nationhood. An admirer of German Nazism he saw Indian identity as synonymous with Hindu culture and saw Muslims, Christians and communists as the enemy within. In his writings he characterised minorities and foreigners as "mlecchas" (म्लेच्छ, namely barbarians or unclean people).References
