1805 Michigan Territory was erected from the northern part of Indiana Territory, and in July following the first General Assembly of Indiana Territory met at Vincennes. In March 1809 the Territory was again divided, Illinois Territory being established from its western portion; Indiana was then reduced to its present limits. In 1810 began the last great Indian war in Indiana, in which the confederated Indians were led by Tecumseh, the celebrated Shawnee chief; it terminated with their defeat at Tippecanoe (the present Battle Ground) by Governor Harrison on the 7th of November 1811. After the close of the second war with Great Britain, immigration began again to flow rapidly into the Territory, and, having attained a sufficient population, Indiana was admitted to the Union as a state by joint resolution of Congress on the 11th of December 1816. The seat of government was established at Corydon, whither it had been removed from Vincennes in 1813. In 1820 the site of the present Indianapolis was selected for a new capital, but the seat of government was not removed thither until 1825. The first great political problem presenting itself was that of slavery, and for a decade or more the only party divisions were on pro-slavery and anti-slavery lines. Although the Ordinance of 1787 actually prohibited slavery, it did not abolish that already in existence. Slavery had been introduced by the French, and was readily accepted and perpetuated by the early American settlers, almost all of whom were natives of Virginia, Kentucky, Georgia or the Carolinas. According to the census of 1800 there were 175 slaves in the Territory. The population of settlers from slave states was considerably larger than in Illinois, the proportion being 20% as late as 1850. It was but natural, therefore, that efforts should at once have been made to establish the institution of slavery on Indiana soil, and as early as 1802 a convention called to consider the expediency of slavery asked Congress to suspend the prohibitory clause of the Ordinance for ten years, but a committee of which John Randolph of Virginia was chairman reported against such action. Within the Territory there were several attempts to escape, by means of legislation, the effects of the Ordinance. These efforts consisted in (1) a law regulating the status of "servants," by which it was sought to establish a legal relation between master and slave; (2) a law by which it was sought to establish practical slavery by a system of indenture. By 1808 the opponents of slavery, found chiefly among the Quaker settlers in the south-eastern counties, began to awake to the danger that confronted them, and in 1809 elected their candidate, Jonathan Jennings (1776-1834) to Congress on an anti-slavery platform. In 1810, by which year the number of slaves had increased to 237, the anti-slavery party was strong enough to secure the repeal of the indenture law, which had received the unwilling acquiescence of Governor Harrison.
