Italian nobility in the context of "House of della Rovere"

The Gherardini family of Montagliari (or Florence) was one of the most prominent historical Italian noble families from Tuscany, Italy. Through the Amideis, the family was of Roman descent. Between the 9th and 14th centuries, they played an important role in Tuscany. Its influence was also felt in the Veneto and Emilia regions between the 16th and 18th centuries, and during the Italian Risorgimento as well as in today's Italian politics and economy. The family's restless and fighting nature has aroused the curiosity of many historians of the Middle Ages. Originating from feudal tradition, it was one of the founding families of the Republic of Florence.

The family took part in Florence's political life between 1100 and 1300. In 1300, they were exiled from the city when Florence began its transformation into a Signoria, later ruled by the Medicis. In his Divine Comedy, Dante Alighieri, who was exiled with the Gherardinis, placed the family in Paradise's V Sphere. Following its exile from Tuscany, the family joined the Great Council of Venice (Venice's Chamber of Peers), becoming Patricians of that city, and members of the Venetian nobility. Until 1800, they kept some fiefs between Tuscany and Emilia Romagna.

The House of Caetani, or Gaetani, is the name of an Italian noble family, originally from the city of Gaeta, connected by some to the lineage of the lords of the Duchy of Gaeta, as well as to the patrician Gaetani of the Republic of Pisa. It played an important role in Rome, in the Papal States and in the Kingdom of Naples, and later in the Kingdom of the Two Sicilies.

Giacomo Medici, Marchese del Vascello (15 January 1817 – 9 March 1882) was an Italian nobleman, patriot and soldier.

Duke of Aosta (Italian: Duca d'Aosta; French: Duc d'Aoste) was a title in the Italian nobility. It was established in the 13th century when Frederick II, Holy Roman Emperor, made the County of Aosta a duchy. The region was part of the Savoyard state and the title was granted to various princes of the House of Savoy, second sons of the reigning king of Sardinia or king of Italy.

The title was re-created in 1845 for Prince Amadeo, son of Victor Emmanuel II, and thereafter held by him and his descendants until the abolition of the Italian monarchy in 1946. Two holders briefly served as kings of European countries – Prince Amadeo ruled as king of Spain from 1870 to 1873, while his grandson Prince Aimone was titular king of Croatia from 1941 to 1943 during the Italian-backed fascist regime.

The House of Tocco (pl. Tocchi, Ancient Greek: Τόκκος, romanized: Tókkos pl. Τόκκοι, Tokkoi) was an Italian noble family from Benevento that came to prominence in the late 14th and 15th centuries, when they ruled various territories in western Greece as Counts Palatine of Cephalonia and Zakynthos and Despots of Epirus. During their brief period of rule in Greece, they were one of the most ambitious and able Latin dynasties in the region, and were one of the few to leave descendants lasting nearly until modern times, in which they claimed to represent the senior matrilineal heirs of the Palaiologos dynasty.

The earliest known members of the family are recorded in the 12th century, in Benevento, though Tocco family genealogies claimed that they originated much earlier, with forged connections to ancient Gothic kings Theodoric the Great and Totila, as well as to the ancient Epirote king Pyrrhus. Members of the family held various prominent offices during the rule of the Hohenstaufen and Angevin dynasties in the Kingdom of Sicily. As a result of the family's loyalty to the Angevin princes in Greece, such as the titular Latin emperors Philip I of Taranto and Robert of Taranto, Leonardo I Tocco was rewarded c.  1357 with the grant of the County Palatine of Cephalonia and Zakynthos, islands off the western coast of Greece.

Giovanni Paolo Lascaris di Ventimiglia e Castellar (Maltese: Laskri) (28 June 1560 – 14 August 1657) was an Italian nobleman and Grand Master of the Knights of Malta.
