The Italian Emigration of Modern Times examines diplomatic issues that arose between Italy and the United States over a series of lynchings of Italian immigrant labourers before World War I. The work explores a significant epoch in Italian economic and diplomatic history which became intertwined with American ethnic and race relations issues. On one level, the book emphasises the pragmatism and restraint which characterized Italy’s official reactions to these repeated episodes of murder of its nationals. On another level, it shows that the diplomatic crises which swirled around the lynching of Italians pushed onto the American political scene the question of whether there should be a federal anti-lynching law. Naturally, the lynching of Italian nationals in the US produced wide public outrage in Italy. Italian domestic outcries presented the Italian government with a serious dilemma. Emigrant savings and financial transfers to family members remaining in Italy were an important economic asset. Italian diplomats launched investigations and protested vigorously, but ended up accepting federal financial compensation for the victims’ families. The consistent pragmatism and restraint of the Italian government through these episodes of violence is the unifying theme of the entire work.

Most studies of immigration to the New World have focused on the United States. Samuel L. Baily's eagerly awaited book broadens that perspective through a comparative analysis of Italian immigrants to Buenos Aires and New York City before World War I. It is one of the few works to trace Italians from their villages of origin to different destinations abroad. Baily examines the adjustment of Italians in the two cities, comparing such factors as employment opportunities, skill levels, pace of migration, degree of prejudice, and development of the Italian community. Of the two destinations, Buenos Aires offered Italians more extensive opportunities, and those who elected to move there tended to have the appropriate education or training to succeed. These immigrants, who adjusted more rapidly than their North American counterparts, adopted a long-term strategy of investing savings in their New World home. In New York, in contrast, the immigrants found fewer skilled and white-collar jobs, more competition from previous immigrant groups, greater discrimination, and a less supportive Italian enclave. As a result, rather than put down roots, many sought to earn money as rapidly as possible and send their earnings back to family in Italy. Baily views the migration process as a global phenomenon. Building on his richly documented case studies, the author briefly examines Italian communities in San Francisco, Toronto, and Sao Paulo. He establishes a continuum of immigrant adjustment in urban settings, creating a landmark study in both immigration and comparative history.
