Answer:
C. a collection of small kingdoms and city states
Step-by-step explanation:
This is the phrase that best describes Italy in the 15th century. During this time period, Italy enjoyed great wealth, artistic development and prestige. However, Italy was not considered a country. Instead, this region was made up of a collection of small kingdoms and city states which were not unified. The unification of Italy would take many more years, and would only be completed centuries later.
