The Stone Age and the Bronze Age
The earliest buildings anyone knows of from India are from Mehrgahr, from about 7000 BC. But the first real stone architecture dates to about 2500 BC, in the Harappan period in northern India (modern Pakistan).

And the Harappans

The Harappans built big cities, with walls around them and public baths and warehouses and paved streets. But when Harappan civilization collapsed, about 2000 BC, almost two thousand years went by before anybody in India built a big stone building again.
When Indian architects did begin to build big buildings again, about 250 BC, at first they built them of wood. Nobody in India knew how to build big stone buildings so they wouldn’t fall down. Architects started by building solid stone buildings, basically mounds of dirt covered with brick or stone like the earlier ziggurats in West Asia and the pyramids in Egypt or Peru. People called these buildings stupas.

What is Buddhism?
Soon after this, about 200 BC, architects began to carve Buddhist temples into the sides of cliffs, so they were taking away stone instead of building with stone. This is easier, so it was a good place to start.
Ajanta and Ellora
But under the Guptan Empire, about 350 AD, Indian architects finally began to build stone temples. These were mainly Hindu temples. Between 350 and 1000 AD, architects built better and better stone temples, especially in southern India, while in northern India they kept on cutting more temples into the side of cliffs, at Ellora and Elephanta.
Free-standing Hindu temples
Slowly Indian architects got better at building temples. Around 500 AD, architects began to use mortar to hold the stones together. Temples got columns around them, and towers over them. About 1000 AD, Indian architects began to replace wood beams with iron beams.
Islamic mosques in India
When Abbasid invaders came to India about 1100 AD, most people in northern India converted to Islam, so Indian architects built a lot of Islamic mosques.

The Chola empire
They often re-used pieces of destroyed Hindu temples to show that they had defeated Hinduism. But in southern India, people went right on building bigger Hindu temples with fancier sculptures carved on them.

Bibliography and further reading about Indian architecture:
India was forced to convert to Islam or die. Shitk have a history of war with Islam when located near China. China forced the two factions to move to the current location of India and Pakistan where the wars continued. Finally the borders were defined into Pakistan Muslim and India Hindu religions. No India person converted willingly. Read your ancient history. To this day the history is passed verbally by India peoples.
Partition, when Muslims moved to Pakistan and Hindus moved to what is now India, was forced on India by the British; it was not an Indian idea. Gandhi opposed it. But long before that, when Islam first came to India, many people living in northern India embraced the new faith, just as people in Iran, Iraq, and China did.
Please say ‘forcefully converted’ or ‘were converted’, no Indian would ever convert to Islam in free will.
There is no evidence to support your assertion; people convert willingly to Islam all the time, and have always done so.
