How many generations does one’s people have to live in a place for them to be recognized as a native? You in your own explanation said the Indians claim a Central Asian Aryan culture blending with the culture of the people of the India valley to constitute a Vedic culture. The Muslims that came to the area so in a similar manner. Be the Arabs that came all the way up to my Multan, from whom I trace my lineage, to the central Asian Muslims that came through and mixed with my ancestors.
If I understand you correctly, I think you think we should be emphasizing our history from the point of view of the Indus Valley civilization much the same way the Egyptians put emphasis on the Ancient Egyptians, as a distinct people, that saw wave upon wave of other migrating through, and today, are the people we see before us. While there is nothing wrong with with that, it all comes down to the narrative arc that unites us as a nation.
This is why, like it or not, Pakistan is the expression of a United Muslim led state on these lands, and the last time Muslims of this region were United under was the Mughals. In a similar way as to how the Turks have to recognize the Ottoman Empire as an evolutionary step in their national identity, we too can not avoid the last Muslim state under which we were unified. Just like the Turks, we don’t have to embrace all the empire did. We don’t need a king nor a similar style of government. This is why we should be studying the culture that was naturally evolving before the British took over. The different view points and sub-cultures (of the decedents of the IVC peoples) that we’re going on under the Mughals.
Garbage or not, they were the last unified Muslim state on our lands. Please elaborate on the class difference changing the perspective.
