The constitution represents the basic legal framework upon which the state's system of government is based. It simultaneously reflects the reality of society and its ongoing developments. Hence, the necessity of constitutional amendment emerges as a mechanism for developing political legitimacy, whether to address gaps in the current constitutional text or to keep pace with political and governance changes occurring in the state. Therefore, the research aims to shed light on the repercussions of the constitutional amendments on the future of the political system and governance in Iraq by analyzing the impact of these amendments on the stability of the political system. In order to achieve this goal, the descriptive analytical approach was relied upon. We have concluded that constitutional amendments are often made for personal reasons that change the political system and form of government, or to favor a person or sectarian group at the expense of constitutional institutions. They may also be made for other reasons, such as in response to external pressures, or sometimes as part of the equation of political consensus. Rarely is an amendment made to meet the actual and necessary needs of the citizen and the people. Therefore, the study recommends pursuing constitutional amendments—in their entirety—to support and enrich the principle of citizenship and consider it the foundation of the state and its political system, as the principle of citizenship is a pillar of democracy.
