Which figure was known for advocating for investments and immigrants in Louisiana?

John Law is recognized for advocating for investments and immigrants in Louisiana during the early 18th century. He was a Scottish economist and financier who played a significant role in promoting the colony as a profitable venture for European investors. Law established the Mississippi Company, which aimed to attract settlers and financial investment to Louisiana, believing that the economic potential of the territory could be realized through increased immigration and capital infusion. His efforts were instrumental in drawing attention to Louisiana as a land of opportunity, thus encouraging many immigrants to settle there in search of prosperity.

General Alexander O'Reilly, Antoine Crozat, and Pierre Le Moyne d'Iberville, while influential in their own right in Louisiana's early history, did not focus on investment and immigration to the same extent as Law did. O'Reilly was mainly known for his military leadership and governance, Crozat for his commercial interests, and d'Iberville for his role as an explorer and founder of the French colony.
