Excerpts from Books and Wikipedia
"In Aghanistan and Pakistan, Mahmud is regarded as a hero; in India he is reviled for destroying so many Hindu holy sites." [Furtado: 1001 Days] "The Punjab region of India and Pakistan has a historical and cultural link to Indo-Aryan peoples as well as partially to various indigenous communities. As a result of several invasions from Central Asia and the Middle East, many ethnic groups and religions make up the cultural heritage of the Punjab. In prehistoric times, one of the earliest known cultures of South Asia, the Indus Valley Civilisation, was located in the region." [Wikipedia]
