In the early years the settlers lived close to the fort along the confluence of the Mississippi and Minnesota rivers, but as a whisky trade started to flourish the military officers in Fort Snelling banned them from the lands the fort controlled with one retired fur trader turned bootlegger, Pierre "Pig's Eye" Parrant, particularly irritating the officials. By the early 1820s the area had become important as a trading center and a destination for settlers heading west and was known as Pig's Eye Landing. In 1841 Father Galtier established the St. Paul Church and that same year the name of the settlement was formally changed to Saint Paul in honor of the newly constructed church and Father Galtier's favorite saint.
