This investigation is concerned with testing a causal model linking changes in a political system's socio-economic environment with alterations in political characteristics. The specific forces of interest are those relating to urbanization and industrialization, the development of that way of life called urbanism, and the effects of these environmental changes on voter participation and, ultimately, inter-party competition. The test model hypothesizes that the processes of urbanization and industrialization together create urbanism, which then affects party competition both indirectly by means of stimulating participation, and directly as well. To illuminate these processes, this study focuses on the American South of the last 30 years because it is in this region that the kinds of changes implicit in the test model have been observed, and thus the region offers the best arena for examining that model.

The main objective of this research is to test some of the hypotheses linking economic development, social mobilization, legitimacy, and the coerciveness of the regime with internal political conflict. Each proposed hypothesis is to be tested across sixteen predominantly Islamic Middle Eastern nations for data from two time periods, 1960-66 and 1967-73. To check for the consistency and strength of the hypothesized relationships the test results for each hypothesis for the first period data will be compared with those of the second period.
