At the beginning of the 20th century, Mexico was in a period of transformation. President
Porfirio Díaz governed the country intermittently from 1876 to 1911. During his tenure, known as the
Porfiriato, Díaz promoted
economic growth by expanding the
railroad network and encouraging foreign investment. These policies benefited the upper class and
landowning elites, but deepened inequality for the middle, working, and lower classes. In 1925, Mexican philosopher
José Vasconcelos (1882–1959) published the essay "" ("The Cosmic Race"), in which he argued that
Native American genes were the last ones to be mixed with the other
human races, would give rise to a new race. This "cosmic race" would ultimately create a Universópolis, a future civilization in which racial and national distinctions would no longer exist. Three years later, the
Día de la Raza was officially celebrated in Mexico for the first time. == History ==
