The Pledge of Allegiance is a statement of loyalty to the United States and its flag. It is often recited at public events, schools, and government meetings. The pledge emphasizes unity and patriotism, reflecting the values of freedom and democracy. Originally written in 1892 by Francis Bellamy, the pledge has undergone several changes. The most notable addition was the phrase "under God," which was included in 1954. Today, it serves as a reminder of the nation's ideals and the commitment of its citizens to uphold them.
