Babur was originally the ruler of

Kabul
Persia
Fargana
Khandahar

The correct answer is A. Kabul.

Babur was the founder of the Mughal Empire in India. He was born in Fergana, in present-day Uzbekistan, in 1483. His father, Umar Shaikh Mirza, was the ruler of Fergana, but he was overthrown in 1494 by his cousin, Muhammad Shaybani Khan. Babur and his family were forced to flee to Kabul, which Babur’s father had previously conquered.

Babur spent the next few years trying to regain his father’s kingdom, but he was unsuccessful. In 1504, he invaded India and defeated the Lodhi dynasty. He established the Mughal Empire in India and ruled it until his death in 1530.

Option B, Persia, is incorrect because Babur was never the ruler of Persia. Persia was ruled by the Safavid dynasty at the time of Babur’s life.

Option C, Fargana, is incorrect because Babur was only the ruler of Fargana for a short period of time. He was forced to flee Fargana in 1494 after his father was overthrown.

Option D, Khandahar, is incorrect because Babur was never the ruler of Khandahar. Khandahar was ruled by the Timurid dynasty at the time of Babur’s life.
