科西莫·德·美第奇
On 3 Jun 1444, Lucrezia married Piero di Cosimo de' Medici, son of Cosimo de' Medici, a wealthy banker and statesman from Florence. Her father was a friend and supporter of Cosimo, even through the latter's exile in 1434. The marriage and her dowry of 1200 florins helped to seal the alliance between their families. Lucrezia and Piero developed a good relationship and frequently wrote to each other while apart with tenderness and concern. She also became a good friend of her brother-in-law Giovanni.
