Extract

No topic encapsulates better the fundamental contradiction in capitalist development in Porfirian Mexico than the turbulent history of the copper industry. Within the space of a few years, the industry simultaneously experienced rapid growth, labour conflict and political controversy with international implications. This historical dynamic was unleashed, in part, by the Mexican government's policy of attracting overseas investors to Mexico through generous concessions and tax breaks that facilitated foreign control over key industries. The privileged position that public policy afforded foreign companies resulted in a nationalist backlash and exacerbated tension between native labour and foreign capital. The famous strike at Cananea, Sonora, in 1906 brought to national attention the grievances of Mexican workers over wage scales that favoured foreign workers over natives, falling real wages, and the power and arrogance of United States companies in Mexico. The strike became a scandal when armed North Americans from nearby Arizona crossed the border and assisted local authorities in crushing Mexican workers. This violation of Mexican sovereignty caused a storm of protest from both liberals and conservatives and unsettled the Díaz regime on the eve of the Mexican Revolution.

His discussion of the 1906 strike appears on pages 131–7. The conflict is also analysed by Camín, Héctor Aguilar in his brilliant political history of Sonora, La frontera nómada (Mexico City, 1985), pp. 114–24Google Scholar.

Demand for copper increased following Faraday's discovery of electromagnetism, and the practical application of electricity by Edison and others. Copper proved ideal for use in motors, generators, wiring, cable, switch gear, particularly in the communication and transportation industries.

7 Bernstein, Marvin offers this assessment of the 1892 law: ‘Since miners were free to claim as much land as they could pay taxes on; work a mine in any manner they might see fit; open or close as their economic personal desires dictated; and employ any number of men they might wish, the mineowner and the speculator in Mexico attained a position of almost complete liberty of action’.

26 His best case is that in 1917 over one-half of the workers had been at the mines for over ten years. But this still may only suggest that these workers sought the security of steady wage employment during the turbulent Revolution. See Romero Gil, El Boleo, Table 22, p. 136.

58 Huginnie presents an excellent discussion of racial, job, and social discrimination against Mexican miners in Arizona. In 1916 the WFM changed its name to the International Union of Mine, Mill, and Smelter Workers and became more conservative. Many Arizona miners were subsequently attracted to the Industrial Workers of the World. See Huginnie, ‘Strikitos’, chs 5 and 6.

88 An anonymous reader for this Journal believes that Baca Calderón forced strikers to adopt a more conservative position. However, the evidence only shows that the formal list of demands presented to Greene did not contain the political rhetoric of the broadside distributed the night before. There is no evidence that Baca Calderón had forced strikers to modify their demands, or that the strike leaders who approached Baca Calderón were the authors of the broadside. Baca Calderón, well-known for his fiery political rhetoric, may or may not have favoured a more conservative position.
