Leaders of Italian City-States: The Signori

In medieval and Renaissance Italy, city-state rulers were called signori (singular: signore) — "lords" or "princes" wielding political and military power.

Notable Signori

• Medici (Florence): Cosimo de' Medici (1434–1464), Lorenzo de' Medici (1469–1492)
• Visconti (Milan): Gian Galeazzo Visconti (1378–1402)
• Este (Ferrara): Borso d'Este (1450–1471)
• Sforza (Milan): Francesco Sforza (1450–1466)
• Gonzaga (Mantua): Ludovico III Gonzaga (1444–1478)

Power structures varied: some hereditary, others maintained through politics and force. The rise of signori reflected wealthy families filling the vacuum of weak central authority.
