That is not a "1,000 year-old Indian parliament building", there was no "Indian government" back then. It's simply a temple, a pretty small one too, with only a radius of 52 meters, but nonetheless of great historic value.
Also, 'trueindologyin' is a horrible source and has made pretty outlandish claims before.
1000 years ago muslims ruled india so trchnically a pakistani parilimentry building isnt it?
1,000 years ago; Muslims did not even rule most of modern-day Pakistan, let alone India.
Also, how does Muslim rule define "what is ours". Pakistanis cannot claim a temple sitting all the way in Uttar Pradesh, unless you are a Muhajir (immigrant) from Uttar Pradesh.
And what was there before 1000 years ? especially in the Present Pakistan ?
Various states that compromised the Indus Region.
Hindu Shahis before that,Maurya and Guptas Empire,before that Porus ruled,before that Madra Kingdom before that Vedic era,before that Indus Valley before that earliest trace of human habitation in whole of region are traced into Soan Valley.
That is extremely inaccurate.
Both the Madra and Porus's Kingdom only ruled a small corner in the North of Punjab. The Kabul Shahis only ruled the Western portion of Pakistan, temporarily taking Punjab and Kashmir at their peak.
Guptas never ruled over parts of modern-day Pakistan, they only maintained tributary states for a very short period.
Mauryans were the only Indian power to have had conquered and held the Indus region for a relevant time-frame, though this period was marked by constant revolts within the Indus Region, especially Gandhara. They were eventually booted out within less than a century.
The Indus region's geopolitical history is often characterized by various petty Kingdoms and tribes that would constantly fight each other, united only periodically and weakly by conquerors from the West (Kushans, Sakas, Indo-Parthians, etc...) who would integrate over time; adopting the customs, culture and religion of the natives.
Only several indigenous polities were able to unite most of the Indus Region, these include the Durrani Empire and the Sindhi Rai Empire.
