The Duke of Alba is a substantive title awarded to members of the Latin Imperial Family. The title has been created eight times, on six occasions to Latin princes, once to an illegitimate child of a Monarch, and once to the cousin of a Monarch. It takes its name from the region of Alba, near the capital region of Latium.

The Dukedom was first created in 991 when it was conferred upon John of Ostia, the illegitimate child of Emperor John II. The line of John of Ostia would eventually become the Imperial line of Latium with the reign of Emperor Theodosius I in 1052, when the title became extinct and merged into the Crown. The third creation came in 1289, when Prince Constantine was conferred the second creation of the Dukedom after his marriage to PLACEHOLDER. The third creation to Prince Constantine also included the subsidiary title of Lord of Pistoria. Before the 2019 creation, most recent creation as on 11 September 1849, when it was granted to Prince John to mark his place as future monarch. He was also created Count of Blachernae, Lord of Hispellum, and Lord of Pistoria.

The eighth, and current, creation came on 10 January 2018 for Prince Leo of Ghant and Latium. Speculation of the grant first came 2016, in the last will and testament of Emperor Jason VI Augustus.

History

A title associated with Alba first arose in the 4th century with the Count Palatinate of Ostia, which was a non-hereditary title held by the Praetorian Prefect of Latium; this Count Palatinate fell out of use by the 7th century. In 970, a mistress to Latin Emperor John II gave birth to a son in the town of Ostia, located southwest of Castellum and the Imperial capital. John II acknowledged and later took the boy, also named John, into the Imperial house. John of Ostia, as he came to be known, was granted the Dukedoms of Ostia and Alba in 991 by Emperor John II. He held the titles and passed it on to his son, and the creation of the House of Ostia. The Ostians were prominent figures in Latin imperial court life, given prominent positions both in the reign of John II and his successor, Constantine XIII. John of Ostia, and his family, were eventually expelled from Latium proper during the reign of Empress Maria Augusta, who reportedly held a disdain for the illegitimate line.

The House of Ostia would eventually come into the Latin throne during the Crisis of the 11th Century, which saw the Latins lose territory across Belisaria and Scipia to native states and invading forces. Theodosius of Ostia, 3rd Duke of Ostia and Alba became Latin Emperor in 1052. Emperor Theodosius I would recreate the Dukedom and bestow it upon his second son, Alexander, in 1077. The Dukedom of Alba has been created seven times in total, and has been extinct since the title merged into the Crown upon the succession of Prince John as Emperor in 1897.
