In the year 650 OE, the Ivetsian monarchy was overthrown as part of the revolutionary movement known as the Great Unrest. From 650 until 715, Ivets was a republic. The Republican government was corrupt and unpopular, becoming increasingly so near the end of its existence. In 715, the ruling Yatta Party restored the monarchy. Tarana Maretska was made the first queen of the restored monarchy. She was the granddaughter of the last King of the old monarchy. Her mother was still alive, but declined to accept the throne due to her age. When the Kasshi Unification Congress agreed to select the Ivetsian monarchy as the new Imperial Dynasty, it was understood that Tarana would become the first Empress of the new empire while remaining Queen of Ivets. However, in 720, she died unexpectedly, leaving the throne to her adolescent daughter Chara Taranakh. At the time, the title of the heir-apparent to the Realm was Lady/Lord Mayor of Ivets, which title was kept when the Empire was founded. As Chara did not yet have children, the title of Mayor went to her brother, Tarana's secondborn, Kronan Taranakh.
In 738, Chara's first child was born, becoming the presumed heir to the throne. At this time, the Ivetsian Throne and the Imperial Throne were separated. Kronan was made King of Ivets while Chara's daughter was made Lady Mayor of Ivets, and an Acting Mayor was designated. The royal capital was moved to the city of Matar and the new title of Lord/Lady Mayor of Matar was created for the heir-apparent to the Ivetsian Throne. A law was passed after Kronan's coronation mandating that the Ivetsian Throne should not merge with the Imperial Throne, that in the event that there should be no direct heirs of Kronan, the throne should pass to a different branch of the House of Tarana
