How would you describe or detail Civic Humanism - specifically that of Florence?

The term "Civic Humanism"
(Bürgerhumanismus) was coined by historian Hans Baron who used it
to describe a reaction against tyranny and foreign invasion. Focussing specifically on
Renaissance Florence, but also echoing the tensions of his own historical era (the
Weimar Republic), Baron found that Florentine citizens faced the threats of absolute
power with a rediscovery of classical models of republicanism based on virtue and active
participation. The tradition of Florentine Civic Humanism thus joined the experience of
the Italian communed of the late Middle Ages and the more modern philosophies of
humanism and classical learning. This union made it possible to conceive the government
of the city as a service to the fulfillment of individuals. Yet, this fulfillment is
always seen in the context of the common good as citizens become actively involved in
the political and economic activities of the city to improve not only their personal
condition but that of the whole community. The key concepts of Civic Humanisn are seen
as having informed the work of philosophers such as Rousseau and Montaigne. They have
also provided the intellectual arguments for American Independence and the French
Revolution. In its more contemporary developments the term has been associated with
Cambridge school philosophers such as John Pocok and Quentin
Skinner.
