The Medici family - controlled Florence throughout much of the Renaissance
The Medici are the first princely dynasty to win their status not by warfare, marriage or inheritance but through commerce. They come to Florence in the 12th century from the nearby countryside. Their ancestral home is in the Mugello valley.

It is only a year before they succeed. Cosimo is invited back, and his rivals are banished - more effectively - for life.
Within the city this control is discreet. Outside, in relations with other powers, it is generally acknowledged that Cosimo
