Wheredid hem sharma sen rule?

Hem sen Sharma or as he is often known Hemu, ruled the Indian subcontinent for about 2 months in an interim takeover.

Explanation:

Hemu was one of the most trusted generals of the Suri dynasty when they took over the rule of the Indian subcontinent from the mughal Humayun who was promptly forced into exile.

When the Suri ruler died and his son too was found to be weak, many people asserted Hemu to crown himself as a ruler as he was a strong leader and so he did.

He would eventually lose his life in battle to Akbar and thus his reign ended very swiftly. So his rule during the turbulent period only lasted for about 2 months and then he was largely forgotten.
