King of Ispolin

The King of Ispolin is a dynastic title handed to the rulers of the Kingdom of Ispolin which has lasted since 334 FL when Petar I, a descendant of Emperor Jivan III of Tyrvopol declared independence from Cysteria and was crowned by a coalition of Ispolinian nobles. The Kingdom was in personal union thrice, first with Tyvopol, then with Vizzetia and finally under Svetossiya. The title is currently held by Ivan XX.

House of Lavski
The House of Lavski has its roots farther than even the Empire of Tyrvopol however it was relatively unknown until Empress Radinija married the Duke of Lav who belonged to the House. The dynasty ruled Tyropol until the city of Tyrvopol was successfully besieged by the Cysterian Empire and its emperor was executed. 2 more emperors of House Istrigijm held this title since, the first was assassinated while the second was forced to abdicate. This was Jivan III, Dukoj of Ispolin Island.

It was the descendant of Jivan, Petar I who together with a coalition of Nobles declared independence from the Cysterian empire in 334 FL, a few years into the reign of Braemus I. This rebellion was brewing for long however Cysterian III's federalist policies and charisma seemed to break the tension. This of course changed when he was assassinated and replaced by Braemus.

House of Jerekol (Union under Svetossiya)
Following a series of bloody wars between Ispolin and Svetossiya the monarchs of the two realms agreed that it was time to end hostilities so Princess Anna, the daughter of King Antjon I of Ispolin would marry the son of Aleksandra II, Prince Kasimir of Svetossiya. This marriage was executed and in 772 Elena gave brith to the future king of Svetossiya. The political climate changed greatly when Elena's older brother Mikhail II died from a disease leaving her to succeed to the throne. This resulted in Josip, the son of Elena and Kasimir being the heir and eventually king of both kingdoms.

House of Tyrvavič
Ruled from 889 when the rebellion against Svetossiya turned into a fully fledged war to 1002 when a short civil war put the House of Lavski in power
