At its peak in 1712 (before the Treaty of Utrecht), the territory of "New France", also sometimes known as the "French North American Empire" or "Royal New France", consisted of five colonies, each with its own administration: Canada, the most developed
Louisiana (New France) at New Orleans (in 1722, four years after the city's founding). The government was led by a Governor-general, and Louisiana became an increasingly important colony in the early 18th century. The earliest settlers of Upper Louisiana mostly came from French Canada, but Lower Louisiana was colonized by people from all over the French colonial empire, with various waves coming from Canada, France, and the French West Indies. Upper Louisiana, also known as the Illinois Country, was the French territory in the upper Mississippi River Valley, including settlements and fortifications in what are now the states of Missouri, Illinois, and Indiana.
