The Black Bands (), sometimes referred to as the Black Bands of Giovanni, was a company of Italian mercenaries formed and commanded by Giovanni de' Medici during the Italian Wars; their name came from their black mourning colors for the death of Pope Leo X. Composed primarily of arquebusiers—including Europe's first mounted arquebusiers—the company was, by the Italian War of 1521, considered to be the finest Italian troops available. Initially in the service of Charles de Lannoy and the Pope, the company fought at Bicocca in 1522 and the Sesia in 1523. A pay dispute led to it transferring its allegiance to Francis I of France; it took part in the battle of Pavia under the command of Richard de la Pole (d. 1525), White Rose.
