Biography
In the cutthroat world of 15th-century Italian politics, Alessandro Sforza was a master of self-invention. The illegitimate brother of the mighty Francesco Sforza, Duke of Milan, Alessandro knew his path to power would be won not by birthright but by the sword. He built his reputation as a capable *condottiero*, a mercenary general whose loyalty was for hire to the highest bidder among Italy's squabbling city-states. His military success was rewarded in 1445 when he purchased the lordship of Pesaro, a strategic coastal city. This move established the Pesaro branch of the sprawling Sforza family, a lineage that would rule for a century. As lord, he proved to be more than a soldier, investing in the city's fortifications and cultural life, and navigating the treacherous alliances between popes, kings, and rival dukes to secure his family's foothold. His life exemplifies the brutal meritocracy of Renaissance Italy, where a shrewd man with a strong army could carve out his own piece of the peninsula.
