So Cosimo de Medici is sent into exile by his enemies. As is the rest of the family. But at least he’s alive. And the business survived. So he’s still FILTHY rich.  It could have been a lot worse. He ends up living at the San Giorgio Maggiore monastery in Venice. Florence is in the control of the Albizzi and the old oligarchy. But the Medici money spigot has been turned off. They aren’t around to bail the city out when it gets into financial trouble – as it always does.
