Laws of justice which Hammurabi, the wise king, established.
Slavery was a central concern of governance form the time of the first nation-state. The Code of Hammurabi, the earliest know set of laws for governing an empire, prescribed death for anyone who harbored a fugitive or otherwise helped a slave to escape.
