They were required to serve overseas

The fact that the sepoys were required to serve overseas upset them during the British East India Company's rule of India.

A sepoy was the designation provided to an Indian infantryman armed with a musket in the armies of the Mughal empire.

The East India Company (EIC), also known as the British East India Company  was an English and later British joint-stock company. It was created seeking to trade in the Indian Ocean region.
