a system of social organization in which property (especially real property and the means of production) is held in common. In modern usage, the term Communism (written with a capital C) is applied to the movement that aims to overthrow the capitalist order by revolutionary means and to establish a classless society in which all goods will be socially owned. The theories of the movement come from Karl Marx, as modified by Vladimir Ilyich Lenin, leader of the successful Communist revolution in Russia. Communism, in this sense, is to be distinguished from socialism, which (as the term is commonly understood) seeks similar ends but by evolution rather than revolution.

Socialism,.
general term for the political and economic theory that advocates a system of collective or government ownership and management of the means of production and distribution of goods. In a broader sense, the term socialism is often used loosely to describe economic theories ranging from those that hold that only certain public utilities and natural resources should be owned by the state to those holding that the state should assume responsibility for all economic planning and direction. In the past 150 years there have been innumerable differing socialist programs. For this reason socialism as a doctrine is ill defined, although its main purpose, the establishment of cooperation in place of competition remains fixed.
Capitalism,.
economic system based on private ownership of the means of production, in which personal profit can be acquired through investment of capital and employment of labor. Capitalism is grounded in the concept of free enterprise, which argues that government intervention in the economy should be restricted and that a free market, based on supply and demand, will ultimately maximize consumer welfare.

Totalitarianism,.
a modern autocratic government in which the state involves itself in all facets of society, including the daily life of its citizens.
