Discourses on Livy

Why it is that changes from freedom to servitude, and from servitude to freedom, are sometimes made without bloodshed, but at other times reek with blood.

Since we find from history that in the countless changes which have been made from freedom to servitude and from servitude to freedom, sometimes an infinite multitude have perished, while at others not a soul has suffered (as when Rome made her change from kings to consuls, on which occasion none was banished save Tarquin, and no harm was done to any other), it may perhaps be asked, how it happens that of these revolutions, some have been attended by bloodshed and others not.
