American Fur Co.

American Fur Co.

Enterprise formed by John Jacob Astor in 1808 that dominated the U.S. fur trade early in the 19th century. The company, considered the first U.S. business monopoly, absorbed or drove out rivals throughout the central and western U.S. Exploration by its trappers and traders helped open the frontier to settlement. By 1834, when Astor sold his company, it had become the largest commercial organization in the U.S.
