A national motto is a phrase or slogan that expresses the beliefs or ideals of a country. It often reflects the values, history, or aspirations of the nation and can be found on official documents, currency, or government buildings. National mottos serve to unify citizens and promote a sense of national identity. Many countries have adopted national mottos, such as the United States' motto, "In God We Trust," which emphasizes faith and reliance on a higher power. Other examples include "Liberty, Equality, Fraternity" from France, highlighting the principles of the French Revolution. These mottos encapsulate the spirit and guiding principles of their respective nations.
