Mouzilo (Greek: Μουζήλο), officially the Kingdom of Mouzilo (Greek: Ρηγάτο του Μουζήλου) is a constituent Kingdom of Rhōmanía. Founded as an independent state in May 2012, Mouzilo's status as an independent state was fully transferred to Rhōmanía, with Mouzilo forming part of the Empire as a self-governing Kingdom.
The current state of Mouzilo and what bore its name prior to 29 May 2020 are separate entities; the present state is reduced in territory and constitutes only part of what was known as the Theme of Mouzilo, an administrative division of the State of Mouzilo. The State reformed into the Basileia of the Romans, whereas the Theme was upgraded to a Kingdom, inheriting the symbols of the former State.
- Mouzilo uses the medieval term Ρηγάτο (rēgato, deriving from the Latin Rex) instead of the modern term Βασίλειο (Basileio) which in the context of Rhomania means Empire
