Conventional theories of ethnic politics argue that political entrepreneurs form ethnic parties where there is ethnic diversity. Yet empirical research finds that diversity is a weak predictor for the success of ethnic parties. When does ethnicity become a major element of party competition? Scholars have explained the emergence of an ethnic dimension in party systems as the result of institutions, mass organizations, and elite initiatives. But these factors can evolve in response to an emerging ethnic coalition of voters. The author advances a new theory: ethnic cleavages emerge when voters seek to form a parliamentary opposition to government policies that create grievances along ethnic identities. The theory is tested on rare cases of government policies in Prussia between 1848 and 1874 that aggrieved Catholics but were not based on existing policies or initiated by entrepreneurs to encourage ethnic competition. Using process tracing, case comparisons, and statistical analysis of electoral returns, the author shows that Catholics voted together when aggrieved by policies, regardless of the actions of political entrepreneurs. In contrast, when policies were neutral to Catholics, the Catholic party dissolved.

The “historical alternatives” approach calls for research into the role of national institutions and public policies in the resilience or decline of industrial districts. Policies in support of small and medium-sized enterprises (SMEs) were launched in various Western economies in the second half of the twentieth century. This article focuses on the paradigmatic Italian case and investigates the importance of government subsidies for SMEs on firms located in a southern and a northeastern district, between 1971 and 1991. This discussion deepens our understanding of the role of national policies in the reemergence of industrial districts in the decades of the Second Industrial Divide. It also indicates the importance of firms’ utilization of subsidies and their ecosystem as complementary to the policy's effectiveness.

This article analyses the gang policies of the first years of the Funes administration in El Salvador, from June 2009 until July 2012. Using securitisation theory, it explains why the administration returned to an emphasis on extraordinary measures, most of them repressive, to deal with gangs. It argues that these measures were the product of an ongoing and dynamic process in which the government was but one of the players in a complex field constituted by numerous actors. The return to repressive measures as well as the support and facilitation of a ‘gang truce’ were not the result of a rational design or a predetermined agenda, but should be seen as a series of moves in a political conjuncture, in which the Salvadorean government needed to communicate to different audiences messages of being in control.
