Roscoe Martin's study of the People's Party in Texas was a pioneering analysis of the state populist movements and long considered one of the best. The People's Party was an influential force in United States politics in the last decade of the nineteenth century, especially in the western and southern states. Martin's study of third-party politics in Texas, as well as being an important work in Texas history, provides much insight into the national radical movement of the 1890s.
