(1400–75), condottiere, born near Bergamo into an aristocratic family with a long military tradition. As a young man he served several condottieri, including Andrea Fortebraccio and Carmagnola. In 1431 he joined the service of Venice and fought the Visconti under the command of Gattamelata, whom he again served in the war against Milan in 1438–41. After the death of Gattamelata, Colleoni fought under Francesco Sforza in 1448. When the Peace of Lodi (1454) settled the disputes between Venice and Milan, Colleoni was appointed captain-general of Venice. In the ensuing years of idleness occasioned by Venice remaining at peace, Colleoni retired to his castle at Malpaga, where he became a lavish patron of the arts and where he died on 2 November 1475.
