What is post westphalian?

Post-Westphalian refers to a contemporary international relations framework that challenges the traditional Westphalian system, which is based on state sovereignty and territorial integrity established by the Peace of Westphalia in 1648. In a post-Westphalian world, the influence of non-state actors, globalization, transnational issues, and the interconnectedness of societies have transformed the dynamics of power and governance. This paradigm recognizes that states are no longer the sole actors in international politics, as global challenges like climate change, terrorism, and human rights transcend national borders and require collective action.
