The first successful European settlement, "Poste de Arkansea," was established by Henri de Tonti in 1686 on the Arkansas River. The post disbanded for unknown reasons in 1699 but was reestablished in 1721 in the same location. Sited slightly upriver from the confluence of the Arkansas River and Mississippi River, the remote post was a center of trade and home base for fur trappers in the region to trade their wares. The French settlers mingled and in some cases even intermarried with Quapaw natives, sharing a dislike of English and Chickasaw, who were allies at the time. A moratorium on furs imposed by Canada severely affected the post's economy, and many settlers began to move out of the Mississippi River Valley. Scottish banker John Law saw the struggling post and attempted to entice settlers to emigrate from Germany to start an agriculture settlement at Arkansas Post, but his efforts failed when Law-created Mississippi Bubble burst in 1720.
