Answer:
1. the Papal States,
The Papal States were territories in central Italy that were directly governed by the papacy—not only spiritually but in a temporal, secular sense. The extent of papal control, which officially began in 756 and lasted until 1870, varied over the centuries, as did the geographical boundaries of the region.
2. the Venetian Republic,
Venice was also an industrial city. It was famous for its glass works, medicines, trades and shipbuilding industry as well as for its vivid cultural environment. The Republic of Venice was ruled by an oligarchy of merchants and aristocrats.
3. the Republic of Florence,
Florence, Italian Firenze, Latin Florentia, city, capital of Firenze provincia (province) and Toscana (Tuscany) regione (region), central Italy. The city, located about 145 miles (230 km) northwest of Rome, is surrounded by gently rolling hills that are covered with villas and farms, vineyards, and orchards
4. the Duchy of Milan,
Milan's climate is continental, with damp, chilly winters and hot, humid summers. Snow falls between December and February, and springtime is generally rainy. In winter temperatures range between 30 and 50 °F (−1 and 10 °C) and in summer between 68 and 86 °F (20 and 30 °C).
5. the Kingdom of Naples
As the most populous holding of the Spanish Empire outside of Castile itself (with 3 million inhabitants in 1600), Naples remained an important source of economic and military power for the Spanish. Heavy taxation was levied upon the kingdom to pay for Spain's wars, especially after 1580.
6. the Kingdom of Sicil
Sicily is both the largest region of the modern state of Italy and the largest island in the Mediterranean Sea. Its central location and natural resources ensured that it has been considered a crucial strategic location due in large part to its importance for Mediterranean trade routes.
