The Domains of the Imperium were established by Emperor Artemus in 72 during the Pacification Campaigns. In 76 the Emperor assigned archdukes to all of the first six domains save Sol. The Domain of Sol includes Diaspora, Old Expanses, Sol, and Alpha Crucis sectors and very little would have been incorporated into the Imperium in 72.
In 704 Empress Margaret I grants a charter for the Solomani Autonomous Region, which encompasses all of the Solomani Rim and Alpha Crucis and approximately half of Diaspora and Old Expanses sectors.
In 716 the Archduchy of Sol lapses, after the death of the incumbent leaves no heirs who are not members of the Solomani Party. The Archduchy remains vacant until 1003, when Arielle Adair is elevated to the title following the Rim War.
When the Archduchy lapsed, what happened to the Domain of Sol -- did it remain an Imperial domain on paper, but admistered by the Domain of Sylea? Or was it effectively dissolved?
