Book excerpt: International borders are among the most significant political inventions of modern times. The borders between national states are not just important to the peoples and governments who face each other across the borderline – any international border can become a regional hotspot of global concern. But aside from the significant role borders play in national and international affairs, borders are also places and spaces where people live, work, raise families, and build businesses. Written for students across disciplines, Borders, Boundaries, Frontiers introduces readers to the study of borders and border cultures. Thomas M. Wilson examines both historical foundations and current developments in the field, with an emphasis on anthropological contributions. Ultimately, Borders, Boundaries, Frontiers encourages students to explore the role anthropology plays in the understanding of contemporary borders.
