Capitani is a surname derived from the medieval title capitano ("captain"), a term ultimately originating from the Latin word caput, meaning "head." During the Middle Ages, the title was used for a variety of political, administrative, military, and judicial offices.

According to E. De Felice and E. Rossoni, the surname developed from medieval forms such as capitànio, capitàneo, cattano, and cattagno. Latinized forms including Capitanus, Capitaneus, Cattanus, and Cattanius are documented from the 12th century.

Rossoni suggests that these surnames generally originated not from direct descendants of a medieval Capitaneus, but rather as nicknames for people who served under, worked for, or were otherwise associated with a captain or local official.

Distribution

According to Rossoni, Capitani is widespread throughout central and northern Italy.

The related surname Capitanio is concentrated mainly in the area between Lombardia and Veneto, with additional branches in Lazio, Abruzzo, and Puglia.

Capitano is particularly associated with Sicilia, especially in the provinces of Palermo and Agrigento, although it is also present in Roma and, to a lesser extent, in the areas of Savona and Napoli.

Variants and Related Surnames

Notes

De Felice notes that surnames beginning with Cap- are generally distributed from southern Italy northward into Emilia-Romagna, while forms beginning with Catt- are found from northern Italy through Toscana and the area of Napoli.

He also suggests that the Lombard surname Cattanei may, in some cases, derive from the place name Cattànea in the province of Pavia rather than directly from the medieval title.

Capitani is an example of an occupational and status-related surname, preserving the memory of medieval administrative, military, and judicial institutions that played an important role in Italian society.
