argues, the two sides had "reached an equilibrium in their rhetorical arguments and critiques". Meanwhile, environmental history has emerged, in large part from the frontier historiography, hence its emphasis on wilderness. It plays an increasingly large role in frontier studies. Historians approached the environment for the frontier or regionalism. The first group emphasizes human agency on the environment; the second looks at the influence of the environment. William Cronon has argued that Turner's famous 1893 essay was environmental history in an embryonic form. It emphasized the vast power of free land to attract and reshape settlers, making a transition from wilderness to civilization. Journalist Samuel Lubell saw similarities between the frontier's Americanization of immigrants that Turner described and the social climbing by later immigrants in large cities as they moved to wealthier neighborhoods. He compared the effects of the railroad opening up Western lands to urban transportation systems and the automobile, and Western settlers' "land hunger" to poor city residents seeking social status. Just as the Republican party benefited from support from "old" immigrant groups that settled on frontier farms, "new" urban immigrants formed an important part of the Democratic New Deal coalition that began with Franklin Delano Roosevelt's victory in the 1932 presidential election. Since the 1960s an active center is the history department at the University of New Mexico, along with the University of New Mexico Press. Leading historians there include Gerald D. Nash, Donald C. Cutter, Richard N. Ellis, Richard Etulain, Margaret Connell-Szasz, Paul Hutton, Virginia Scharff, and Samuel Truett. The department has collaborated with other departments and emphasizes Southwestern regionalism, minorities in the Southwest, and historiography.
