Adoption was a common and formal process in Roman culture. Its chief purpose had nothing to do with providing homes for children; it was about ensuring the continuity of family lines that might otherwise become extinct. In early Rome, this was especially important for the patricians, who enjoyed tremendous status and privilege compared with the plebeians. Because few families were admitted to the patriciate after the expulsion of the kings, while the number of plebeians continually grew, the patricians continually struggled to preserve their wealth and influence. A man who had no sons to inherit his property and preserve his family name would adopt one of the younger sons from another family. In time, as the plebeians also acquired wealth and gained access to the offices of the Roman state, they too came to participate in the Roman system of adoption.
