The Pledge of Allegiance to the United States is an oath of loyalty to 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 Boy Scouts of America, and some sporting events.

The current version of the Pledge of Allegiance reads:

"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."
