The Kingdom of Sicily (NeapolitanRegno 'e Sicilia, SicilianRegnu di Sicilia), which comprises of the southern part of the Italian Peninsula, as well as the island of Sicily, is a feudal elective monarchy.

It is the re-established monarchy of the thirteenth-century Kingdom of Sicily. The original monarchy was effectively ended after the island of Sicily seceded from the country after the Vespers of 1282. Under a personal union with Milan starting in the mid-fifteenth century, Sicily was recovered. In 1482 - 1484, Naples and Sicily waged a successful independence war and re-established the Kingdom of Sicily.

The ruler elected by the Council of Sicily is known as the Prince-General.


Before 1400

For early history about the Kingdom of Naples see this article: Kingdom of Naples

1400 to 1500

In the early 15th century, King Ladislaus largely had to deal with quelling the last of the rebellions in favor of Louis II, the former pretender king. Once that ended with the executions of Onorato Caetani, the count of Fondi and the last rebellions in Apulia and Abruzzo being crushed, Naples largely attempted to rebuild itself by improving its damaged infrastructure and expanding it across the barren countryside.

The nation has once again gone to war against Venice after it unlawfully demanded a Neapolitan vassal's territory as a part of a separate peace deal with Genoa.

From 1454 to 1484, Naples continued to be the junior partner in the Italian union, being the subject of an increasingly powerful country. However, starting in the late 1460s, Italy had engendered massive conflict in Europe and was suffering greatly. Austria, Bulgaria, and Spain, as well as many other European powers, warred on Italy and Naples. By 1482, Naples had erupted in revolt due to protracted war and economic ruin. Within a few years, the Italian authority was overthrown and a Sicilian noble was elected to the throne. Sicily transformed into an elective monarchy known as the Regency-Generalship.

1500 to 1600

In 1571, Philip I of House Valois was elected by the Noble Council as Prince-General of the Kingdom of Sicily.


Italian Crisis (1729-present)

Following a diplomatic incident in 1729 involving the Sicilian Prince-General's visit to Venice, tensions flared between Sicily and the Italian League, which eventually led to a polarization of Italian, and European, geopolitics. The European nations began taking sides over who to support on the peninsula, with Belka (a Belkan envoy famously shouting: "LEAVE THE [Italian] LEAGUE ALONE!"), Poland, Britain, and Russia supporting the League, and Iberia, the Papal States, and (secretly) Austria supporting Sicily. Even the Sultanate of the Maghreb has attempted to support the Italian League, and France and Savoy have received offers to support Sicily. Both parties have agreed to a mediation by the Papal States, yet tensions could flare again, and war could break out in the new "powderkeg of Europe"...
