Florence, 1429. Giovanni de’ Medici is a rich banker who also represents one of the most important political forces of Florence’s Signoria. He has a plan to increase his family power by making an agreement with the Church of Rome. The election of a new Pope is about to take place and Giovanni sends his sons Cosimo and Lorenzo to Rome in order to encourage the election of a Pope close to his family. In Rome, Cosimo, fascinated by the beauty of ancient architectures and art, meets Donatello and one of his models Bianca. Cosimo falls in love with her but is then forced to leave her and marry Contessina de Bardi, a political marriage arranged by Giovanni and Contessina’s father. The Medici’s candidate gets elected, which ensures to the bank of the Medici an unparalleled economic power. Twenty years later, Giovanni is mysteriously murdered and Cosimo and Lorenzo try to secretly investigate his death. Meanwhile, the political situation in the city is troubled by plots against the Medici family’s power, and their vision for the future of Florence – which will then lead to the Renaissance – is in danger.
Cosimo’s dream is to complete the Duomo of Florence, but no architect seems to have a feasible solution due to the shape of the base created for the dome. Finally, Filippo Brunelleschi introduces himself to Cosimo and shows him plans for the dome. Cosimo decides to trust Brunelleschi and the construction of the dome starts, bringing jobs and people to Florence. Meanwhile, the mystery surrounding the death of Giovanni thickens and Rinaldo Albizzi, Cosimo’s main opponent in the Signoria, tries to block the construction and to incite the people to rise up against the Medicis.Medici: Masters of Florence Season 1-3.
