Information: - The Roman emperor was the ruler of the Roman Empire during the imperial period (starting in 27 BC). The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title "Augustus" or "Caesar". Another title often used was "imperator", originally a military honorific. Early Emperors also used the title "princeps" (first citizen). Emperors frequently amassed republican titles, notably "Princeps Senatus", "Consul" and "Pontifex Maximus". - A martyr (Greek: , "martys", "witness"; stem -, "martyr-") is somebody who suffers persecution and death for advocating, renouncing, refusing to renounce, or refusing to advocate a belief or cause as demanded by an external party. This refusal to comply with the presented demands results in the punishment or execution of the martyr by the oppressor. Originally applied only to those who suffered for their religious beliefs, the term is now often used in connection with people imprisoned or killed for espousing a political cause. - In the Eastern Orthodox tradition, a hieromartyr is a martyr (one who dies for his beliefs) who was a bishop or priest.
