This chapter provides a critical background on the country cases by examining their brief political histories as independent states. It also gives critical information about the legal frameworks of such states to highlight where and how Islamist groups can act in these states. By providing such descriptions, this chapter demonstrates the extent to which these states, in regime or popular politics, either adhere or fail to adhere to the government type and political environment normally associated with the rentier state. The chapter also reveals critical commonalities among the super-rentier states—they are governed by powerful ruling families; institutionalized political life is hampered; and civil society and political life remain largely informal—while also indicating their differences, which arose in light of their differing sociocultural and economic backgrounds.
