Final answer:
France emerged as a constitutional monarchy under the Constitution of 1791, with the new parliamentary body named the Legislative Assembly.
Step-by-step explanation:
As a result of the Constitution of 1791, France became a constitutional monarchy, a form of government that limits the power of the monarch. The constitution ensured that the monarch's power stemmed from the people rather than from divine right. This shift aimed to embody Enlightenment principles such as natural rights, representative government, equality before the law, and freedom of expression. The newly formed parliamentary body, tasked with governance and legislative reform, was named the Legislative Assembly. This governmental structure was considerably influenced by Enlightenment thinkers like John Locke and Baron de Montesquieu who argued for the separation of powers and constitutional governance.
Despite this new government, internal tensions and external pressures continued to challenge the fledgling constitutional monarchy. Conflict between political factions in the Legislative Assembly, the failed escape of King Louis XVI, and the unease it caused within other European monarchies marked a period of instability which eventually led to further developments in France's governmental structure.
