Fort Ouiatenon was originally constructed by the French government in 1717 as a military outpost to protect against Great Britain's western expansion. Its location among the unsettled woodlands of the Wabash River valley also made it a key center of trade for fur trappers. French merchants and trappers from Quebec would arrive at Fort Ouiatenon in search of beaver pelts and to take advantage of trade relations with the native Wea Native American tribes.
