Exarch
An "Exarch" is a title used in various Christian traditions, particularly within the Eastern Orthodox Church and the Catholic Church. It typically refers to a bishop or a high-ranking ecclesiastical official who has authority over a specific region or group of churches. The role often involves overseeing the spiritual and administrative needs of the community.
In historical contexts, the term "Exarch" was also used to describe governors of certain provinces in the Byzantine Empire. These officials were responsible for both civil and military matters, acting as representatives of the emperor in distant territories.
