Banking on Italy
The third largest bank of modern day Italy is established this year and will remain in continuous operation. The name of the bank is "Monte dei Pietà" which means "Mountain of Pity" or Lamentation. The bank has since changed its name to "Monte dei Paschi di Siena" [mon-tay day pas-kee dee see-EN-ah] (MPS). It is located in Siena which is under the influence of Florence. In another 5 years or so, the political situation in Siena will become so chaotic, the city will opt for a dictatorship. Florence will come under a single ruler shortly thereafter.   
Leonardo Joins an Artists Guild
Leonardo da Vinci joins the Guild of Artists of Florence. This is quite a feat since he is only 22 years old. This is also the time when he will begin such works as "The Baptism of Christ" with his teacher, Andrea del Verrocchio. Many paintings of the day were collaborative works with pupils painting backgrounds and minor characters in a scene or taking on extra work that the master didn't have time for. At this point Leonardo is definitely doing the grunt work. If he wants to strike out on his own he must be a member of the guild. Of course it costs money to join and it's not so much that the guild gets you work, but that NOT being in the guild definitely locks you out of work.

ISBN 9781567310160. “"[Cosimo de' Medici's] loans to influential families won or forced their support; his gifts to the clergy enlisted their enthusiastic aid; and his public benefactions, of unprecedented scope and generosity, easily reconciled the citizens to his rule. [...] If the populace had to choose between the Albizzi, who favored the rich, and the Medici, who favored the middle classes and the poor, it could not long hesitate. A people oppressed by its economic masters, and weary of faction, welcomed dictatorship in Florence in 1434, in Perugia in 1389, in Bologna in 1401, in Siena in 1477, in Rome in 1347 and 1922."”

But the honor of belonging to a guild certainly didn't come free. The guild's record books show that Leonardo was behind on his dues at least once.”
