Altiero

Altiero is a masculine given name of Italian origin. It is relatively uncommon in modern usage and is primarily found in Italy. The name is most closely associated with a 20th-century political figure who played a pivotal role in European federalist thought.

The most prominent bearer is Altiero Spinelli (1907–1987), an Italian political activist and a leading advocate of European federalism. While imprisoned on Ventotene during World War II, Spinelli co-authored the Ventotene Manifesto (1941), a foundational document arguing for a free, federated Europe and for the creation of supranational institutions to ensure lasting peace and unity.

Spinelli’s ideas significantly influenced the postwar European integration project. He is regarded as a key precursor to the European Union, contributing to the development of concepts and structures that supported greater political and economic integration among European states. The legacy of his work is reflected in the continuing emphasis on federalist approaches within European integration advocacy.

As part of his legacy, the European Parliament has honored Spinelli in part by naming a building after him—the Altiero Spinelli Building—alongside other named facilities that commemorate figures associated with European integration. The name Altiero thus remains most strongly associated with Spinelli and with the broader history of European federalism.

In summary, Altiero, while a relatively rare Italian given name, is chiefly recognized for its association with Altiero Spinelli, a key figure in the early movement toward a united Europe and the federalist philosophy that helped shape modern European institutions.
