Bourgeois women had been carving a space for themselves in the lettered world since the beginning of the nineteenth century, and by the late 1880s dozens of them were publishing books and journals. Working-class, lower middle-class, and immigrant women became literate and entered writing as part of their involvement in politics, trade unions, and education. This chapter discusses the writing of professional and working women between 1880 and 1930. It describes massive immigration, especially to countries such as Argentina, Brazil, Uruguay, and Chile; the expansion of economic markets; the Mexican Revolution; and the ripple effects of World War I. While at the beginning of this period, most women who wrote belonged to the upper and middle classes, by the 1930s working-class women were involved in writing and publishing and had an important presence in the political press. Through travel writing, women rendered visible a world more and more complicated by relations of power and displacement.
