At this time, the French population of Illinois amounted to about three thousand persons, who were settled along the Mississippi and Illinois rivers, where their descendants remain to this day, preserving a well-defined national character in the midst of the great flood of Anglo-American immigration which rolls around them.

Illinois remained under British rule till the year 1778, when George Rogers Clarke, with four companies of Virginia rangers, marched from Williamsburg, a distance of thirteen hundred miles, through a hostile wilderness, captured the British posts of Kaskaskia and Cahokia, and annexed a territory larger than Great Britain to the new Republic.  Many of Colonel Clarke’s rangers, pleased with the beauty and fertility of the country, settled in Illinois; but the Indians were so numerous and hostile, that the settlers were obliged to live in fortified stations, or block-houses, and the population remained very scanty for many years.

In 1809 Illinois was made into a separate Territory, and Ninian Edwards appointed its first Governor.

During the War of 1812, Tecumseh, an Indian chief of remarkable ability, endeavored to form a coalition of all the tribes against the Americans, but with only partial success.  He inflicted severe losses upon them, but was finally defeated and slain at the Battle of the Thames, leaving behind him the reputation of being the greatest hero and noblest patriot of his race.

In 1818, Illinois, then having a population of about forty-five thousand, was admitted into the Union.  The State was formed out of that territory which by the Ordinance of 1787 was dedicated to freedom; but there was a strong party in the State who wished for the introduction of slavery, and in order to effect this it was necessary to call a convention to amend the Constitution.  On this arose a desperate contest between the two principles, and it ended in the triumph of freedom.  Among those opposed to the introduction of slavery were Morris Birkbeck, Governor Coles, David Blackwell, Judge Lockwood, and Daniel P. Cook.  It was a fitting memorial of the latter, that the County of Cook, containing the great commercial city of Chicago, should bear his name.  The names of the pro-slavery leaders we will leave to oblivion.

In 1824 the lead mines near Galena began to be worked to advantage, and thousands of persons from Southern Illinois and Missouri swarmed thither.  The Illinoisans ran up the river in the spring, worked in the mines during the summer, and returned to their homes down the river in the autumn,—­thus resembling in their migrations the fish so common in the Western waters, called the Sucker.  It was also observed that great hordes of uncouth ruffians came up to the mines from Missouri, and it was therefore said that she had vomited forth all her worst population.  Thenceforth the Missourians were called “Pukes,” and the people of Illinois “Suckers.”
