Definition
An alternative spelling of "Caesar." In Roman law, a cognomen originating within the Gens Julia — the patrician Roman family to which Julius Caesar belonged — that was subsequently assumed as a title by his imperial successors. As the Roman Empire developed, "Caesar" evolved from a personal family name into an official designation of imperial authority, eventually functioning as a general title for the emperor or his designated heir.
The term appears in historical legal dictionaries primarily as a point of reference for understanding Roman constitutional and administrative vocabulary. It has no operative legal meaning in modern Anglo-American law.

Common Language
Modern common usage (Wiktionary): "Caesar" is used to refer to Julius Caesar himself, to Roman emperors generally, or metaphorically to any supreme ruler or dictator. "Czar" (or "tsar") — a direct linguistic descendant — is used in modern English both for the historical Russian monarchs and colloquially for a powerful official appointed to oversee a specific policy area (e.g., "drug czar," "energy czar").
Historical common usage (Webster's 1913): Caesar — "A Roman emperor, as being the successor of Augustus Caesar. Hence: Any powerful or imperial ruler; an autocrat."
The legal meaning is narrower than the common meaning. In Roman law sources, "Caesar" carried specific constitutional weight as a title with defined succession implications, distinguishing the reigning emperor from a designated co-emperor or heir. The colloquial modern usage (policy czar) bears no legal relationship to the Roman law term.

Common Confusion
The variant spellings — Caesar, Czsar, Czar, Tsar, Kaiser — all descend from the same Roman cognomen but carry different historical and jurisdictional contexts. "Czsar" as spelled here is an uncommon variant, likely a transcription artifact in older printed legal dictionaries rather than a standardized legal spelling. Researchers encountering this form in historical sources should treat it as equivalent to "Caesar" in the Roman law sense. Do not conflate the Roman law title with "czar" as used in modern U.S. administrative parlance, which is an informal designation without statutory definition or constitutional grounding.

Why It Matters in Research
This term is primarily a navigational artifact. Researchers working in Roman law sources, civil law treatises, or early common law texts that drew on Roman foundations may encounter "Caesar" and its variant spellings as shorthand for imperial authority or imperial legal pronouncements (rescripts, constitutions). The authority of Roman emperors to issue binding legal declarations — and the title "Caesar" as the source of that authority — appears in foundational civil law texts that influenced later European legal systems.
The specific spelling "Czsar" is rare and likely reflects a typographical or orthographic convention in a particular edition or printing of Black's Law Dictionary (2nd Ed.) rather than a distinct legal term of art. If you encounter it in a primary source, verify the edition and context before drawing meaning from the spelling itself.
Corpus researchers should note that Taylor's *Elements of the Civil Law* (cited in Black's as "Tayl. Civil Law, 31") is the underlying source for the dictionary entry. Researchers needing depth on the Roman law context should go to that treatise rather than treating the dictionary entry as authoritative on Roman constitutional structure.

Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) gives only a brief entry, identifying "Czsar" as a cognomen in the Gens Julia assumed by Julius Caesar's successors, with a single citation to Taylor's Civil Law. The entry does not address the constitutional evolution of the title, the distinction between "Caesar" as a personal name versus an imperial title, or the later divergence into European royal titles (Kaiser, Tsar/Czar). No other source dictionaries were available for this entry, so cross-dictionary synthesis is not possible. The entry as it stands is a minimal identification, not an analysis.
