Constantinian constitutions in later codes restrict Jewish slaveholding and conversion-adjacent acts

Later imperial codes preserve constitutions in Constantine’s name that penalised Jewish ownership of Christian slaves and conversion of Christians, a legal disability cluster conventionally dated from 315 onward. In the causal graph this event weakens Protection of Minority Rights, a driver that strengthens Having a say in government — a worsening welfare path.

Read the full account

Later imperial codes preserve constitutions in Constantine’s name that penalised Jewish ownership of Christian slaves and conversion of Christians, a legal disability cluster conventionally dated from 315 onward.

Context

This is not medieval expulsion. It is a privileging of the newly favoured cult against a named minority. Medium confidence on exact wording versus later compilers.

Constantine the Great’s documented role is bounded by other offices and collaborators named in the sources below.

Codex Theodosianus is a 438 compilation. Constitutions under Constantine’s name against Jews converting Christians or holding Christian slaves are later-copied law, not a 315 autograph plaque.

Why it matters

A code heading is not a pogrom count.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

What the sources establish

Grenoble’s Roman-law pages and Britannica independently treat Constantinian-era Jewish disabilities in the codes as received law.

Established: codes transmit Constantinian constitutions disadvantaging Jews on slaves and conversion. Not established: a 315 synagogue census, or that he drafted every later anti-Jewish line in the Theodosian book.
