ry, they still retained a measure of party cohesion under William Wyndham and acted as a united, though unavailing, opposition to Whig corruption and scandals. At times they cooperated with the "Opposition Whigs", Whigs who were in opposition to the Whig government; however, the ideological gap between the Tories and the Opposition Whigs prevented them from coalescing as a single party.
Emergence of the two-party system in Britain
The old Whig leadership dissolved in the 1760s into a decade of factional chaos with distinct "Grenvillite", "Bedfordite", "Rockinghamite", and "Chathamite" factions successively in power, and all referring to themselves as "Whigs". Out of this chaos, the first distinctive parties emerged. The first such party was the Rockingham Whigs under the leadership of Charles Watson-Wentworth and the intellectual guidance of the political philosopher Edmund Burke. Burke laid out a philosophy that described the basic framework of the political party as "a body of men united for promoting by their joint endeavours the national interest, upon some particular principle in which they are all agreed". As opposed to the instability of the earlier factions, which were often tied to a particular leader and could disintegrate if removed from power, the two party system was centred around a set of core principles held by both sides and that allowed the party out of power to remain as the Loyal Opposition to the governing party.
A genuine two-party system began to emerge, with the accession to power of William Pitt the Younger in 1783 leading the new Tories, against a reconstituted "Whig" party led by the radical politician Charles James Fox.
The two party system matured in the early 19th century era of political reform, when the franchise was widened and politics entered into the basic divide between conservatism and liberalism that has fundamentally endured up to the present. The modern Conservative Party was created out of the 'Pittite' Tories by Robert Peel, who issued the Tamworth Manifesto in 1834 which set out the basic principles of Conservatism; - the necessity in specific cases of reform in order to survive, but an opposition to unnecessary change, that could lead to "a perpetual vortex of agitation". 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 proto two-party political system, the Federalist Party and the Democratic-Republican Party, centred around 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.
