Following the Louisiana Purchase in 1803, US Army officer Zebulon Pike negotiated approximately of land from the local Dakota tribes in 1805 to establish a fort. The negotiated territory was located on both banks of the Mississippi River, starting from Saint Anthony Falls in present-day Minneapolis, to its confluence with the Saint Croix River. Fort Snelling was built on the territory in 1819 at the confluence of the Mississippi and Minnesota rivers, which formed a natural barrier to both Native American nations. The 1837 Treaty with the Sioux ceded all local tribal land east of the Mississippi to the U.S. Government. Taoyateduta (Chief Little Crow V) moved his band at Kaposia across the river to the south. Fur traders, explorers, and missionaries came to the area for the fort's protection. Many of the settlers were French-Canadians who lived nearby. However, as a whiskey trade flourished, military officers banned settlers from the fort-controlled lands. Pierre "Pig's Eye" Parrant, a retired fur trader-turned-bootlegger who particularly irritated officials, set up his tavern, the Pig's Eye, near present-day Lambert's Landing. By the early 1840s, the community had become important as a trading center and a destination for settlers heading west. Locals called the area "Pig's Eye" (French: "L'Œil du Cochon") or "Pig's Eye Landing" after Parrant's popular tavern. In 1841, Father Lucien Galtier was sent to minister to the Catholic French Canadians and established a chapel, named for his favorite saint, Paul the Apostle, on the bluffs above Lambert's Landing. Galtier intended for the settlement to adopt the name Saint Paul in honor of the new chapel. In 1847, a New York educator named Harriet Bishop moved to the area and opened the city's first school. The Minnesota Territory was formalized in 1849 and Saint Paul named as its capital. In 1857, the territorial legislature voted to move the capital to Saint Peter. However, Joe Rolette, a territorial legislator, stole the physical text of the approved bill and went into hiding, thus preventing the move. On May 11, 1858, Minnesota was admitted to the union as the thirty-second state, with Saint Paul as the capital. That year, more than 1,000 steamboats were in service at Saint Paul, making the city a gateway for settlers to the Minnesota frontier or Dakota Territory.
