Francis Rory Peregrine "Perry" Anderson is a British intellectual, historian and essayist. His work ranges across historical sociology, intellectual history, and cultural analysis. What unites Anderson's work is a preoccupation with Western Marxism.

The New Left was a broad political movement that emerged from the counterculture of the 1960s and continued through the 1970s. It consisted of activists in the Western world who campaigned for a broad range of social issues such as feminism, gay rights, drug policy reforms and the rejection of traditional family values, social order, and gender roles. The New Left differs from the traditional left in that it tended to acknowledge the struggle for various forms of social justice, whereas previous movements prioritized explicitly economic goals. However, many have used the term "New Left" to describe an evolution, continuation, and revitalization of traditional leftist goals.
