assigned to administer the civilian government of the District of Louisiana. He conducted the district's affairs for five weeks until the Louisiana Territory was formally established on July 4, 1805, and Brigadier General James Wilkinson assumed the duties of governor. In 1805, Harrison built a plantation-style home near Vincennes that he named Grouseland, in tribute to the birds on the property. The 26-room home was one of the first brick structures in the territory; and it served as a center of social and political life in the territory during his tenure as governor. Harrison founded a university at Vincennes in 1801, which was incorporated as Vincennes University on November 29, 1806. The territorial capital was eventually moved to Corydon in 1813, and Harrison built a second home at nearby Harrison Valley. Harrison's primary responsibility was to obtain title to Indian lands that would allow future settlement and increase the territory's population, a requirement for statehood. He was also eager to expand the territory for personal reasons, as his political fortunes were tied to Indiana's eventual statehood. While benefiting from land speculation on his own behalf, and acquiring two milling operations, he was credited as a good administrator, with significant improvements in roads and other infrastructure. When Harrison was reappointed as the Indiana territorial governor on February 8, 1803, he was given expanded authority to negotiate and conclude treaties with the Indians. The 1804 Treaty of St. Louis with Quashquame required the Sauk and Meskwaki tribes to cede much of western Illinois and parts of Missouri. Many of the Sauk resented the loss of lands, especially their leader Black Hawk. Harrison thought that the Treaty of Grouseland (1805) appeased some of the Indians, but tensions remained high along the frontier. The Treaty of Fort Wayne (1809) raised new tensions when Harrison purchased more than 2.5 million acres (10,000 km2) from the Potawatomi, Delaware, Miami, and Eel River tribes. Some Indians disputed the authority of the tribes joining in the treaty. Harrison was also able to conduct matters unquestioned by the government, as the administration changed hands from Jefferson to Madison. He pursued the treaty process aggressively, offering large subsidies to the tribes and their leaders, so as to gain political favor with Jefferson before his departure. Biographer Freehling asserts that the Indians perceived the ownership of land was as common to all, just as the air that is breathed. In 1805,
