How did the ancient Romans view promises and other verbal contract?

The ancient Romans placed significant importance on promises and verbal contracts, viewing them as binding commitments rooted in trust and mutual obligation. They believed that a promise (promissio) created a moral and social duty, which was often enforced through legal means. Although written contracts were preferred for clarity and proof, verbal agreements held considerable weight in Roman society, reflecting the cultural emphasis on honor and integrity. Breaching a promise could lead to social stigma and legal repercussions, highlighting the seriousness with which Romans regarded these commitments.
