Long before they were adopted in Italy, the names of Guelf and Ghibeline had been employed in Germany to mark the partisans of the Bavarian Welf and of the Hohenstaufen lords of Waiblingen. On Italian soil they received an extended meaning: Ghibeline stood for Imperialist; Guelf for anti-Imperialist, Papalist, or simply Nationalist. When the names began to be freely used in Florence, which was towards the close of Frederick's reign and about a century after their first invention, they denoted no new start in politics, but only supplied a nomenclature for parties already in existence. As far as Florence was concerned, the designations were the more convenient that they were not too closely descriptive. The Ghibeline was the Emperor's man, when it served his purpose to be so; while the Guelf, constant only in his enmity to the Ghibelines, was free to think of the Pope as he chose, and to serve him no more than he wished or needed to. Ultimately, indeed, all Florence may be said to have become Guelf. To begin with, the name distinguished the nobles who sought alliance with the citizens, from the nobles who looked on these as they might have done on serfs newly thriven into wealth. Each party was to come up in turn. Within a period of twenty years each was twice driven into banishment, a measure always accompanied with decrees of confiscation and the levelling of private strongholds in Florence. The exiles kept well together, retreating, as it were in the order of war, to camps of observation they found ready prepared for them in the nearest cities and fortresses held by those of their own way of thinking. All their wits were then bent on how, by dint of some fighting and much diplomacy, they might shake the strength and undermine the credit of their successful rivals in the city, and secure their own return in triumph. It was an art they were proud to be adepts in.[8]
