and the area which exclusively engages itself with urdu is right now Only Pakistan.. Exclusively because, its the only region where the spoken and written urdu language is practiced on National level.

I belong to Pakistan, but as far as i know from my History, it wasn't a native language, infact, it emerged from the mixture of different languages, especially, the arabic and the Persian. In my own perspective, to have another distinct language having the arabic (religious) script, was a sign to our being a different nation from the Hindus. It reflected our ideology and that we're one nation, having our own rights, our own beliefs and values, we're just Not the minority but we deserved a separate homeland where we could practice our core values, amongst which was also our National Language i-e Urdu.
