Adoption in ancient Rome

Adoption in ancient Rome was primarily a legal procedure for transferring paternal power (potestas) to ensure succession in the male line within Roman patriarchal society. The Latin word adoptio refers broadly to "adoption", which was of two kinds: the transferral of potestas over a free person from one head of household to another; and adrogatio, when the adoptee had been acting sui iuris as a legal adult but assumed the status of unemancipated son for purposes of inheritance. Adoptio was a longstanding part of Roman family law pertaining to paternal responsibilities such as perpetuating the value of the family estate and ancestral rites (sacra), which were concerns of the property-owning classes and cultural elite. During the Imperial era, adoption became a way to ensure imperial succession.

In contrast to modern adoption, Roman adoptio was neither designed nor intended to build emotionally satisfying families and support childrearing. Among all social classes, childless couples or those who wanted to expand the size of their families instead might foster children. Evidence is meager for the adoptio of young children for purposes other than securing a male heir, and probably would have been employed mostly by former slaves legitimating the status of their own children born into slavery. Roman women could own, inherit, and control property as citizens, and therefore could exercise prerogatives of the paterfamilias pertaining to ownership and inheritance,[1] but adoption was largely a male-gendered practice.[2]
