Answer:
French common laws
Step-by-step explanation:
Most of the American laws were born with the constitution of the country. These laws evolved as time went on and the US needed to update some sentence for the law to remain valid and effective today. When the American constitution was created, the laws were inspired by the common French laws, since at that time France was the only example of a prominent republican regime. What prevailed throughout the world were monarchical regimes, mostly absolutists.
