*154. The Liberals and Reform.*--The political history of this second great era of Whig ascendancy falls into some four or five stages. The first, extending from the accession of the Grey ministry in 1830 to the parliamentary elections of 1841, was an epoch of notable reforms, undertaken and carried through mainly by the Whigs, with the co-operation of various radical elements and of discontented Tories. This was the period of the first Reform Act (1832), the emancipation of slaves in the British colonies (1833), the beginning of parliamentary appropriations for public education (1833), the Factory Act of 1833, the New Poor Law (1834), the Municipal Corporations Act (1835), and a number of other measures designed to meet urgent demands of humanity and of public interest. This was the time, furthermore, at which the party nomenclature of later days was brought into use. The name Whig was superseded altogether by that of Liberal, while the name Tory, though not wholly discontinued in everyday usage, was replaced largely by the term Conservative.[213] The Liberals were in these years peculiarly the party of reform, but it must not be inferred that the Conservatives resisted all change or withheld support from all measures of amelioration. [Footnote 213: The name Conservative was employed by Canning as early as 1824. Its use was already becoming common when, in January, 1835, Peel, in his manifesto to the electors of Tamworth, undertook an exposition of the principles of what he declared should be known henceforth as the Conservative--not the Tory--party.]
