2.5 Roman Law Form
Article 60 - Usucapio
Canon 5811 (link)
To maintain the argument of lawfulness, the Romans invented even further legal fictions concerning Usucapio whereby certain land could be claimed as “ownerless” and therefore could be “lawfully occupied” (occupation) as private ownership – excluding temples – by the first person to take possession. Thus, these extraordinary claims opened up a ready made motive for legions and their leaders to conquer their enemies as the only permitted private land was conquered land.
