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.
