Explanation:

During the twelfth and thirteenth centuries, the Florentines actively participated in the wars between Guelphs and Ghibellines, factions vying for the succession of the imperial crown. The Guelphs defended paper power and were against noble privileges, while the Ghibellines, supported by the German Emperor, opposed the power of the Pontiff. Florence was predominantly Guelfa. The nobility was very weakened by these struggles and was expelled from power in 1293, opening the period of the second people.

At that time Florence was the first city in Tuscany, as Pisa had been defeated by Genoa in 1284 and Siena was beginning to decline. The city was one of the most active in Italy. The businesses were family owned and had branches throughout western Europe. The older companies were still involved in the dispute between whites and blacks, factions into which the Guelphs were divided, and suffered their consequences. These political conflicts did not prevent Florence from establishing banks and becoming one of the most powerful and prosperous cities in Europe, where trade was headed, unlike Venice, which expanded into the Mediterranean.

An example of its power was the creation of the "golden guilder" in 1252, a currency that would remain for more than three centuries as one of the world's monetary standards alongside the Venetian duchy.

From 1326, the new companies were dedicated to the commerce, the industry and the most important economic activity, the financial one. The Florentines organized the large-scale loan: they lent money to the sovereigns of Europe in exchange for leasing taxes.
