The current international situation is characterised by increasing political unrests in the area of the Arab world. In many Middle-Eastern countries there occurred collapse of state structures and many-year civil wars broke out. Political chaos in the Arab world has been increasing for over a dozen years and it seems to be rather a result of structural flaws inherent in the political systems of countries in this region, rather than accidental events. These facts provoke to an attempt at deeper analysis of the circumstances and search for some general features. One of the immediately noticeable features of the situation is that political anarchization concerns Arab republics, whereas monarchies are distinguished by significantly greater internal stability. The reasons for the downfall of republics are internal problems as well as conflicts with western powers. Also in this case one may notice political rowdiness of the republican leaders in Egypt, Iraq and Libya and compare it with more stable and responsible politics of monarchies. Generally premodern monarchial legalism in the Arab world turns out to be a more effective political idea than the rule of sovereignty of nations. This is a noteworthy fact, although it is contradictory to western political dogmas.
