The Pledge of Allegiance of the United States is an oath of loyalty to the national flag and the republic of the United States of America, originally composed by Francis Bellamy in 1892. The Pledge has been modified four times since then, with the most recent change adding the words "under God" in 1954. The Pledge is predominantly sworn by children in public schools in response to state laws requiring the Pledge to be offered. Congressional sessions open with the swearing of the Pledge, as do government meetings at local levels, meetings held by the Knights of Columbus, Boy Scouts of America, other organizations, and many sporting events.

I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation under God, indivisible, with liberty and justice for all.

According to the United States Flag Code,
the Pledge "should be rendered by standing at attention facing the flag with the right hand over the heart.

When not in uniform men should remove any non-religious headdress with their right hand and hold it at the left shoulder, the hand being over the heart. Persons in uniform should remain silent, face the flag, and render the military salute."
