In 1946, Luís Carlos Prestes became the first self-proclaimed Communist Senator of Brazil, a feat which would only be repeated sixty years later, when Inácio Arruda was elected to represent Ceará. By 1947, the PCB had nearly 200,000 members, having received 480,000 votes (nearly 9% of the total) in that year's legislative election. The party, however, was denounced as being "internationalist, and therefore not committed to Brazil's own interests" by Eurico Gaspar Dutra in 1948, having its license revoked by the Electoral Justice Court. In 1956, clashes emerged in the party after Nikita Khrushchev denounced Joseph Stalin's policies at the 20th Congress of the Communist Party of the Soviet Union. The factionalization of the PCB accelerated after a new Manifesto was approved in 1958, proposing new ways of achieving communist goals, linking the establishment of socialism to the broadening of democracy. Some of its top leaders, dissatisfied with this guidelines, quit PCB and formed a new party, Communist Party of Brazil (Partido Comunista do Brasil – PCdoB), in 1962. As a result, both parties claim to have been established in 1922.
