Legitimacy plays a crucial role in establishing and maintaining order in the global system by providing a framework for states to interact and cooperate with each other.

Power is not a source of legitimacy in international relations, as it does not provide a normative justification for the authority of a state or international organization.

Legitimacy contributes to the effectiveness of international institutions by increasing compliance with international rules and norms, enhancing their ability to resolve conflicts and disputes, and facilitating cooperation and collaboration among states.

A lack of legitimacy in international relations can lead to increased conflict and instability, reduced cooperation and collaboration among states, and weakened international institutions.

Legitimacy in international relations can be strengthened by promoting transparency and accountability in international institutions, ensuring that international rules and norms are fair and just, and involving a wide range of stakeholders in decision-making processes.

Legitimacy is a necessary condition for sovereignty, as it provides a normative justification for the authority of a state to exercise control over its territory and population.

Legitimate interventions are more likely to be successful, less likely to be resisted by the target state, and more likely to be supported by the international community.

Legitimacy can play a crucial role in the peaceful resolution of international conflicts by helping to create a conducive environment for negotiations, building trust between conflicting parties, and ensuring that the terms of a peace agreement are fair and just.

Legitimacy can help to prevent conflict and instability, promote cooperation and collaboration among states, and strengthen international institutions, all of which contribute to the stability of the international system.

The rise of non-state actors, the increasing interconnectedness of the world, and the decline of the nation-state are all challenges to legitimacy in international relations.

Legitimacy in a globalized world can be promoted by creating more inclusive and participatory international institutions, promoting transparency and accountability in international decision-making, and ensuring that international rules and norms are fair and just.

Legitimacy can play a crucial role in the global governance of climate change by helping to build trust and cooperation among states, ensuring that climate change policies are fair and just, and mobilizing resources and support for climate change action.

Legitimate international environmental agreements are more likely to be complied with, supported by the public, and effective in achieving their goals.

Legitimacy is a necessary condition for the responsibility to protect, as it provides a normative justification for the use of force to protect civilians in other states.

Legitimacy in the global governance of migration can be promoted by involving migrants in decision-making processes, ensuring that migration policies are fair and just, and promoting transparency and accountability in migration governance.
