Ohioans have always been a very religious people. In the prehistoric period, Ohio's native people constructed earthworks. Both modern-day scholars and American Indians contend that these mounds, in all likelihood, held some religious meaning to their builders. Among the first whites in what would become Ohio were Moravian missionaries, who sought to convert the Delaware Indians to Christianity. As white settlers moved into the area in the late eighteenth and the early nineteenth centuries, they quickly established churches. Most early Ohioans favored the Presbyterian Church and the Methodist Church, but soon every major Christian denomination existed in the state. During the twentieth century, Ohio's religious pluralism only increased, as numerous non-Christian faiths arrived in Ohio. Ohioans' religious beliefs also have influenced politics, including in the early twenty-first century, when Ohio voters amended the state constitution to make marriage only between a man and a woman.
