Final answer:
The Peace of Westphalia codified the principles of state sovereignty, laying the foundations for the modern system of nation-states, rather than eliminating hierarchy, establishing divine rights of kings, or creating a global government.
Step-by-step explanation:
The Peace of Westphalia was a series of peace treaties signed between May and October 1648 in the Westphalian cities of Osnabrück and Münster, largely ending the European wars of religion. The treaties that comprised the Peace of Westphalia brought about significant changes in the political landscape of Europe. It did not eliminate hierarchy altogether, nor did it create a global government.
It also did not establish the divine right of kings; rather, that concept had been a critical legitimating factor for monarchical rule for some time, particularly enlightening the rule of absolute monarchs such as Louis XIV. Instead, the Peace of Westphalia codified the principles of state sovereignty, which includes a state's absolute right to govern its territory and population without external interference. This principle laid the groundwork for the modern international system of independent nation-states and effectively marked the end of the medieval idea of a universal Christian empire.
