Leyawiin is located on top of the Niben River Estuary. The main city is located on the western side of the Trans-Niben. The island in the middle of the estuary is where Castle Leyawiin is located. In the western part of the main city is the chapel, guilds, and merchants while the eastern part of the main city is on the river and is where the residents stay.
In 1E 243 the Alessian Slave Rebellion had come to an end and Pelinal Whitestrake had been put to rest after a conflict with Umaril the Unfeathered. A messenger carried the Mace of the Crusader to the city of Leyawiin. Later on, Saint Kaladas built the Great Chapel of Zenithar in honor of the Mace.
In the mid-second era, Varen Aquilarios of Chorrol led a rebellion against Emperor Leovic for his decision to legalize Daedric worship in Cyrodiil. The city of Leyawiin was liberated single-handedly by Sai Sahan. He fought Emperor Leovic's forces and his own men realizing they were double agents.

In the fourth century of the third era, County Leyawiin was annexed back into the Imperial Province from an agreement between the Mane and Emperor Uriel Septim VII. Because of this, an infamous group of Khajiiti bandits known as the Renrijra Krin sought to reclaim the Trans-Niben by blaming then Count Marius Caro for forcing the local Khajiits out of the county's fertile land. Because of it's proximity to both Elsweyr and Black Marsh, Leyawiin holds many Khajiit and Argonian traditions and cultures.
After the Oblivion Crisis, Leyawiin became an independent city-state. It waged war against Bravil, which had also become an independent city-state. Both countries fought each other until Titus Mede I subdued both nations.
