you took the wrong approach in desiging the civilization IMO. The italian civilization wasn't born in 1861 (which is only the date of political unity of the italian state) but way before, and its major achievements come also before this date, in particular from the Renaissance. Your UB, UU and leaders are all from the modern age, which has little to offer. For example, with all the UBs that you could come up with, the modern football stadium, which isn't even unique or originary from Italy, is really a poor choice IMO.
For the leader, I would say Lorenzo de'Medici. There's even his LH ready on this forum.
