A "Gentlemen's Agreement" is an informal, unwritten agreement between parties, often based on trust and mutual understanding rather than legal obligations. These agreements are typically used in situations where formal contracts may be impractical or unnecessary, relying on the integrity of the involved parties to uphold their commitments. Historically, the term is associated with various social and political contexts, such as the Gentlemen's Agreement of 1907 between the United States and Japan, which aimed to limit Japanese immigration. While these agreements can foster cooperation, they may also lead to misunderstandings if one party fails to honor the terms.
