The genealogies here are simplified for space and clarity. For a more detailed chart, see Wikipedia Italia.
Part 1 covers the Medici family from almost the earliest (relatively) well-documented generation to Salvestro, who established a brief populist dictatorship as I discuss here, and Vieri, who would take in his impoverished cousin Giovanni di Bicci and put him on the path to becoming a wealthy banker.
Part 2 and 3 follow the line of Giovanni di Bicci, who established the Medici bank as a major international business, to Lorenzo “the Magnificent”.
Part 4 follows the descendants of Lonrenzo “the Magnificent” with particular attention on the ties between Lorenzo and Queen Catherine de’ Medici as well as the line of Medici Grand Dukes of Tuscany.
Part 5 follows the descendants of the “Popolano” line from Cosimo de’ Medici’s brother, Lorenzo “the Elder”, to Grand Duke Cosimo I.
