What is the title given to the financier who took control of Nouvelle France for five years?

The correct answer is Antoine Crozat, who was granted a proprietary concession by King Louis XIV in the early 18th century. Crozat was responsible for managing French Louisiana, then known as Nouvelle France, for five years beginning in 1712. His role was significant as he was tasked with establishing a profitable colony, though his venture faced many challenges, including difficulties in generating sufficient revenue and conflict with Native American tribes. This experience laid the groundwork for future colonization efforts in the region.

While other figures like John Law contributed to the economic development through ideas like the Mississippi Bubble, their roles were distinct and took place in different contexts. Pierre Le Moyne d'Iberville is known for his exploration and founding of settlements but did not hold control over Nouvelle France in the same way. Sieur de la Salle was instrumental in the early exploration of the Mississippi River and claimed Louisiana for France but did not have the same financial or administrative authority Crozat had during his term.
