Settlement of Mount Pleasant began in the early 19th century, and increased following the construction of the Military Road connecting Nashville and Madisonville, Louisiana, in 1817. By the time Mount Pleasant incorporated as a city in 1824, it was home to a store, tavern, and several churches.

In 1895, brown phosphate rock was discovered in Mount Pleasant, leading to a mining boom, and giving the city its nickname.
