Conservative Party

British political party whose guiding principles include promotion of private property and enterprise, maintenance of a strong military and foreign policy, and preservation of traditional cultural values and institutions. It is the heir of the old Tory Party, whose members began forming “conservative associations” after electoral rights were extended to the middle class in 1832.

The modern party (whose members are often known as Tories) is essentially a coalition of two groups, and must balance its traditionalist and communitarian wing against its libertarian and individualist wing. It also experiences internal conflict over Britain's relationship with the European Union. Its membership is heavily dependent on the landowning and middle classes, but its electoral base has extended at times to incorporate about one-third of the working class. Since World War I, it and the Labour Party have dominated British politics.
