Plymouth is a city in Marshall County, Indiana, United States. The population was 10,033 in the 2010 census. It is the county seat of Marshall County. Plymouth was the site of the first retail outlet of defunct U.S. retailer Montgomery Ward in 1926. This area was part of the territory of the Potawatomi Native Americans, one of the historical tribes encountered by European-American settlers. In the nineteenth century, the United States government made numerous treaties to buy and extinguish Native American claims to land in the former Northwest Territory and the Southeast. Marshall County was formed in 1836, during the early years of settlement and before the forced removal of the Potawatomi people in 1838.
It was named for U.S. Chief Justice John Marshall, who died in 1835. Marshall County is notable as the starting point in 1838 of the Potawatomi Trail of Death, which was the forced removal by United States forces of Chief Menominee and 859 Potawatomi Indians from Indiana to Indian Territory, at the site of present-day Osawatomie, Kansas, a distance of 660 miles (1,060 km). The first settlers arrived in what is now Marshall County in 1835. They arrived as a result of the end of the Black Hawk War as well as the completion of the Erie Canal. They consisted primarily of settlers from New England, “Yankees” descended from the English Puritans who settled New England in the colonial era.
