Latin America is the former Spanish American empire in the Western Hemisphere plus Portuguese Brazil. Professional historians pioneered the creation of this field, starting in the late nineteenth century. The term “Latin America” did not come into general usage until the twentieth century and in some cases it was rejected. The historiography of the field has been more fragmented than unified, with historians of Spanish America and Brazil generally remaining in separate spheres. Another standard division within the historiography is the temporal factor, with works falling into either the early modern period (or “colonial era”) or the post-independence (or “national”) period, from the early nineteenth onward. Relatively few works span the two eras and few works except textbooks unite Spanish America and Brazil. There is a tendency to focus on histories of particular countries or regions (the Andes, the Southern Cone, the Caribbean) with relatively little comparative work.
