The Conservative Party (also known as Tories) is the oldest political party in the United Kingdom and arguably the world. The current party was first organised in the 1830s and the name "Conservative" was officially adopted, but the party is still often referred to as the Tory party (not least because newspaper editors find it a convenient shorthand when space is limited). The Tories had been a coalition that often formed the government from 1760 until the Reform Act 1832. Modernising reformers said the traditionalistic party of "Throne, Altar and Cottage" was obsolete, but in the face of an expanding electorate from the 1830s to 1860s, it held its strength among royalists, devout Anglicans and landlords and their tenants.
Widening of the franchise in the 19th century led the party to popularise its approach, especially under Benjamin Disraeli, whose Reform Act 1867 greatly increased the electorate. After 1886, the Conservatives allied with the part of the Liberal Party known as the Liberal Unionists who opposed their party's support for Irish Home Rule and together they held office for all but three of the following twenty years. Lord Salisbury's and Arthur Balfour's governments between 1895 and 1906 were given the name of "Unionist". The Conservative Party was also known as the Unionist Party in the early 20th century. In 1909, the Conservative Party was renamed the Conservative and Unionist Party and in May 1912 it formally merged with the Liberal Unionists.
