Caesar (title)
Caesar ( English language, English  Caesars; Latin  ; in Greek: ) is a title of imperial character. It derives from the ''cognomen'' of Julius Caesar.

When used on its own, the title denoted heirs apparent, who would later adopt the title ''Augustus (title), Augustus'' on accession. The title remained an essential part of the style of the emperors, and became the word for "emperor" in some languages, such as German () and Slavic ().
