In the early Common Era, the regulations concerning slave-ownership by Jews underwent an extensive expansion and codification within the Talmud. The precise issues that necessitated a clarification to the laws is still up for debate. The majority of current scholarly opinion holds that pressures to assimilate during the late Roman to early medieval period resulted in an attempt by Jewish communities to reinforce their own identities by drawing distinctions between their practices and the practices of non-Jews. One author, however, has proposed that they could include factors such as ownership of non-Canaanite slaves, the continuing practice of owning Jewish slaves, or conflicts with Roman slave-ownership laws. Thus, the Babylonian Talmud (redacted in 500 CE) contains an extensive set of laws governing slavery, which is more detailed than found in the Torah.
