Communist Youth (UTC) wing—as Cassian recalled in 2008, they were motivated by a will to "change the world for the better", abhorring both antisemitism and fascism. Colin married Nina Cassian in 1943. The two divorced five years later, and Cassian remarried Al. I. Ştefănescu. During their period together, both Cassian and Colin grew close to writer and literary critic Ovid Crohmălniceanu, later known as a Communist Party activist, as well as to future literary historian Geo Şerban and translator Petre Solomon. Later, Colin was again married, to graphic artist Marcela Cordescu. Communist writer After the August 1944 Coup against the pro-Axis Antonescu and the start of Soviet occupation, Colin became a noted supporter of left-wing causes. That year, at the age of twenty-three, he also graduated from Bucharest's Cantemir Vodă High School and had his first poem published in Victoria journal. The piece was titled Manifest ("Manifesto") and signed Ştefan Colin. Colin studied at the University of Bucharest's Faculty of Letters, but left institution after only one year, spending much of his time working for the UTC, which employed him as publisher of its books.

After the establishment of a Romanian Communist regime, Vladimir Colin became noted for his vocal support of the new authorities. In 2006, the Presidential Commission for the Study of the Communist Dictatorship in Romania nominated him (together with Ştefănescu, Sorin Toma, and others) among the prominent Communist activists responsible for censorship. In parallel, he was pursuing a career as a poet: his debut volume 27 de poeme
