In this section, we explore the concept of the state, an institution defined by its political apparatus governing a territorial area—comprising governance structures like parliaments and legal systems that enforce authority, often backed by military power to implement policies. The state is analyzed through different sociological lenses: the functionalist perspective sees it as representing societal interests, while the conflict perspective suggests it serves the dominant social sections. The signification of sovereignty embodies the unquestioned political control of a state. Moreover, the section delves into the evolution of citizenship rights, illustrating how struggles have expanded the notion from political exclusion to a broader understanding of civil, political, and social rights. Historical examples include the struggles for civil rights and the pursuit of equality in citizenship roles, notably concerning gender representation and social welfare. Overall, the chapter highlights the complex interplay of historical developments, social structures, and the tension between collective identity and individual rights within the state framework.
