Communist Party of the United States of America (CPUSA), also called Communist Party USA, is left-wing political party in the United States that was, from its founding in 1919 until the latter part of the 1950s, one of the country’s most important leftist organizations. Its membership reached its peak of 85,000 in 1942, just as America entered World War II; the CPUSA had rallied enthusiastically in favour of a Soviet-American war effort against Nazi Germany.
In 1919, inspired by Russia’s October Revolution (1917), two U.S. communist parties emerged from the left wing of the Socialist Party of America (SPA): the Communist Party of America (CPA), composed of the SPA’s foreign-language federations and led by the sizeable and influential Russian Federation, and the Communist Labor Party of America (CLP), the predominantly English-language group. They were established legally but were soon forced underground. Although the two parties feuded and various factions broke away to establish competing communist groups, the Communist International encouraged the unification of those organizations. In 1922 the CPA merged with the United Communist Party (which had been established when the CLP joined a breakaway faction of the CPA) to create the legal and aboveground Workers Party of America (WPA). When the United Toilers of America, a group that adopted the same tactics as the WPA, combined with the latter organization, the party renamed itself the Workers (Communist) Party, finally settling on the name Communist Party of the United States of America in 1929.

The Cause That Failed by
In The Cause that Failed, Lewy offers an incisive narrative of the American Communist Party from the days of John Reed to the advent of glasnost.
Claudia Vera Jones was a Trinidad and Tobago-born journalist and activist. As a child, she migrated with her family to the US, where she became a Communist political activist, feminist and black nationalist, adopting the name Jones as "self-protective disinformation". Due to the political persecution of Communists in the US, she was deported in 1955 and subsequently lived in the United Kingdom. Upon arriving in the UK, she immediately joined the Communist Party of Great Britain and would remain a member for the rest of her life. She then founded Britain's first major black newspaper, the West Indian Gazette, in 1958, and played a central role in founding the Notting Hill Carnival, the second-largest annual carnival in the world.
Left of Karl Marx by
In Left of Karl Marx, Carole Boyce Davies assesses the activism, writing, and legacy of Claudia Jones (1915–1964), a pioneering Afro-Caribbean radical intellectual, dedicated communist, and feminist. Jones is buried in London’s Highgate Cemetery, to the left of Karl Marx—a location that Boyce Davies finds fitting given how Jones expanded Marxism-Leninism to incorporate gender and race in her political critique and activism.
Claudia Cumberbatch Jones was born in Trinidad. In 1924, she moved to New York, where she lived for the next thirty years. She was active in the Communist Party from her early twenties onward. A talented writer and speaker, she traveled throughout the United States lecturing and organizing. In the early 1950s, she wrote a well-known column, “Half the World,” for the Daily Worker. As the U.S. government intensified its efforts to prosecute communists, Jones was arrested several times. She served nearly a year in a U.S. prison before being deported and given asylum by Great Britain in 1955. There she founded The West Indian Gazette and Afro-Asian Caribbean News and the Caribbean Carnival, an annual London festival that continues today as the Notting Hill Carnival. Boyce Davies examines Jones’s thought and journalism, her political and community organizing, and poetry that the activist wrote while she was imprisoned. Looking at the contents of the FBI file on Jones, Boyce Davies contrasts Jones’s own narration of her life with the federal government’s. Left of Karl Marx establishes Jones as a significant figure within Caribbean intellectual traditions, black U.S. feminism, and the history of communism.
