The Socialist Equality Party (United States)

Join the SEP in building a mass, international movement of workers and youth to defend democratic rights and secure a socialist future.

Capitalism has failed in the United States and around the world. The Socialist Equality Party is building a revolutionary movement of the working class to put an end to inequality, exploitation, and the profit system itself. We are fighting for the socialist reorganization of economic life, based on the expropriation of the corporate and financial oligarchy and the transformation of major industries into public utilities, democratically controlled and operated to meet social needs, not private profit.

The SEP is spearheading the fight against dictatorship, war, and the growth of fascism. The return of Trump to power and the advance of far-right movements internationally express the breakdown of capitalist democracy. The defense of democratic rights requires the independent mobilization of the working class against the entire political establishment and the capitalist system it defends.

To organize this struggle, the SEP and its sister parties internationally have initiated the building of the International Workers Alliance of Rank-and-File Committees (IWA-RFC). These committees are a means for workers to unify their struggles across factories, industries, and national borders, and to assert their own power in opposition to the union bureaucracies, the corporations, and the capitalist state.

Socialism, moreover, cannot be realized in one country. All the great problems confronting mankind are global problems that require global solutions.

Socialism cannot be achieved in one country. The SEP fights for the international unity of the working class on the basis of a common program and perspective. We work in political solidarity with the International Committee of the Fourth International, the world party of socialist revolution founded by Leon Trotsky in 1938.

This page contains key documents and statements on the history and program of the SEP. We urge you to study them carefully, discuss them with others, and take the decisive step of joining and building the Socialist Equality Party. The fight against capitalism, dictatorship, and war depends on the conscious leadership of the working class. Be part of this struggle! Join the SEP!

Historical Foundations of the SEP

The program of the Socialist Equality Party is of a principled, not of a conjunctural and pragmatic character. It is based on an assimilation of the strategic revolutionary experiences of the working class and the international socialist movement.

The SEP traces its political ancestry to the fight for Trotskyism in the US that was initiated in 1928, when veteran revolutionary James P. Cannon, along with Canadian revolutionary Maurice Spector, declared their support for Trotsky's fight against the Stalinist degeneration of the Soviet Union.

The international Trotskyist movement has a long history of principled struggle against Stalinism, reformism and bourgeois nationalism. In the United States, the fight for Trotskyism was carried forward by the Socialist Workers Party (SWP), founded in 1938 under the leadership of Cannon, and then the Workers League, which was founded in 1966 after opposing the national opportunist degeneration of the SWP.

The Workers League, in political solidarity with the International Committee of the Fourth International, based its perspective on the revolutionary role of the American working class in opposition to all forms of nationalism and revisionism, as well as the pro-capitalist politics of the trade union bureaucracy. The Workers League played a significant role in many of the major battles of the working class in the 1970s and 1980s.

The Workers League was transformed into the SEP in 1995, which was followed by a similar transformation of all the sections of the ICFI.

Cliff Slaughter: A Political Biography (1928–1963)

Cliff Slaughter died on May 3, 2021, in Leeds, England, at the age of 92. His enduring contribution in the 1960s to the defense of Trotskyism stands in tragic contrast with his subsequent political opportunism and repudiation of revolutionary Marxism.
