What contributed to the rise of the italian states during the renaissance

What contributed to the rise of the Italian states during the Renaissance were the following: thriving trade, no central power, and struggle for power between France and Spain. The trade in Italy was beginning to become better and better with each passing day, which obviously contributed to the creation of their states. No central power meant that each of these states ruled in its own state, there wasn't anything or anyone that connected these states. With the power control between France and Span, Italy also had to prepare for anything and thus the first states were formed.
