Antonio Graziadei

When the First World War broke out, he positioned himself as a maximalist socialist, and in 1921, he was among the founders of the Communist Party of Italy (PCd'I).

He distanced himself both from the group around the review L'Ordine Nuovo by Antonio Gramsci, and from that of Amadeo Bordiga, and instead sided with the right wing led by Angelo Tasca.

With the advent of the fascist dictatorship, he lost his seat as a deputy, suffered attacks, experienced isolation, and finally saw himself excluded from the university environment.

After the collapse of the Fascist dictatorship, he was made a member of the Consulta Nazionale and obtained his readmission to the PCI.

Although a convinced Marxist in politics, on the other hand unorthodox in the field of Marxian economics, most notably regarding the concept of the labor theory of value.
