Meanwhile, the Whigs, along with free trade Tory followers of Robert Peel, and independent Radicals, formed the Liberal Party under Lord Palmerston in 1859, and transformed into a party of the growing urban middle-class, under the long leadership of William Ewart Gladstone. The two party system had come of age at the time of Gladstone and his Conservative rival Benjamin Disraeli after the 1867 Reform Act. History of American political parties Although the Founding Fathers of the United States did not originally intend for American politics to be partisan, early political controversies in the 1790s saw the emergence of a two-party political system, the Federalist Party and the Democratic-Republican Party, centred on the differing views on federal government powers of Secretary of the Treasury Alexander Hamilton and James Madison. However, a consensus reached on these issues ended party politics in 1816 for a decade, a period commonly known as the Era of Good Feelings. Partisan politics revived in 1829 with the split of the Democratic-Republican Party into the Jacksonian Democrats led by Andrew Jackson, and the Whig Party, led by Henry Clay. The former evolved into the modern Democratic Party and the latter was replaced with the Republican Party as one of the two main parties in the 1850s.
