Mr. Douglas was elected State’s Attorney of the First Judicial District in 1835. In 1836 he was elected to the Illinois legislature. The following year he was appointed Register of Public Lands at Springfield, to which place he removed. In 1841 he was appointed Secretary of State; but soon resigned, to accept the office of Judge of the Supreme Court of the State. In 1843 Mr. Douglas was elected to Congress, where he served for two terms; he was re-elected to the House for the third term, but at the following session of the legislature, December, 1846, he was chosen for the United States Senate, of which he remained a member until his death. Senator Douglas died on the 3d of June, 1861. [Illustration: STEPHEN A. DOUGLAS] LINCOLN-DOUGLAS DEBATE FIRST JOINT DEBATE, DELIVERED AT OTTAWA, ILL., AUGUST 21, 1858 _Douglas’s Opening Speech_ LADIES AND GENTLEMEN:--I appear before you to-day for the purpose of discussing the leading political topics which now agitate the public mind. By an arrangement between Mr. Lincoln and myself, we are present here to-day for the purpose of having a joint discussion, as the representatives of the two great political parties of the State and Union, upon the principles in issue between those parties; and this vast concourse of people shows the deep feeling which pervades the public mind in regard to the questions dividing us. Prior to 1854, this country was divided into two great political parties, known as the Whig and Democratic parties. Both were national and patriotic, advocating principles that were universal in their application. An old-line Whig could proclaim his principles in Louisiana and Massachusetts alike. Whig principles had no boundary sectional line; they were not limited by the Ohio river, nor by the Potomac, nor by the line of the free and slave States, but applied and were proclaimed wherever the Constitution ruled or the American flag waved over the American soil. So it was and so it is with the great Democratic party, which from the days of Jefferson until this period has proven itself to be the historic party of this nation. While the Whig and Democratic parties differed in regard to a bank, the tariff, distribution, the specie circular, and the sub-treasury, they agreed on the great slavery question which now agitates the Union. I say that the Whig party and the Democratic party agreed on the slavery question, while they differed on those matters of expediency to which I have referred. The Whig party and the Democratic party jointly adopted the compromise measures of 1850 as the basis of a proper and just solution of the slavery question in all its forms. Clay was the great leader, with Webster on his right and Cass on his left and sustained by the patriots in the Whig and Democratic ranks, who had devised and enacted the compromise measures of 1850. * * * * *
