Judah ha-Nasi traditionally compiled the Mishnah, the earliest major written collection of Jewish oral law.
Known simply as Rabbi or Rabbeinu HaKadosh, Judah ha-Nasi lived in Roman Palestine around the late second and early third centuries CE. Jewish tradition credits him with editing and arranging teachings that had previously been transmitted primarily by memory.
The Mishnah is organized into six orders covering subjects such as agriculture, festivals, women and family law, civil and criminal matters, sacrifices, and ritual purity. Its concise Hebrew preserves many earlier debates, often recording minority opinions alongside the ruling view.
The Mishnah is not the same as the Talmud. The Talmud contains the Mishnah together with later discussions called Gemara. Hillel and Akiva were influential earlier sages, but neither is credited with compiling the final Mishnah.
