The study aims to explain the variations in the state of democratization in the countries of the region covered by the events of the Arab Spring, as well as to identify the factor (s) underlying the changes. Six countries were selected for analysis; half of them have undergone major changes, the other half - minor political changes. The theory of modernization and the theory of Huntington about the waves of democratization are used. The chosen method is a comparative method together with a quantitative analysis. The result shows that, contrary to the modernization theory and hypothesis, economic and socio-economic development does not explain the changes in the state of democratization. Countries with little political change are somewhat more developed. The result suggests that other factors, such as economic decline and the resilience of the monarchy, may explain the differences in the state of democratization as a result of the Arab Spring.
