"The Republican Party, which developed rapidly as a new political force following the enactment of the Kansas-Nebraska Bill in 1854, gathered its strength chiefly from those who opposed the extension of slavery into the territories. In the Lincoln - Douglas Debates this issue was paramount. Perhaps nowhere can a more concise and explicit statement of the position of the Republican Party on this issue be found than in Mr. Lincoln's opening speech at Quincy [Illinois] in the sixth of the joint debates".
