In this episode, the Books Brothers walk through Paul Strathern’s The Medici and trace how a single Florentine banking family helped push Europe out of the medieval world and into the Renaissance. Giovanni builds the bank, Cosimo expands it across Europe while funding libraries and scholars, and Lorenzo turns cultural power into political influence. Along the way the brothers explore church corruption, the Great Schism, early financial innovation, the rediscovery of classical ideas, and the artists who reshaped Florence. The Medici story becomes a clear example of how money, ideas, and ambition helped create the foundations of the modern state.
