Answer:
The first recorded recitation of the Pledge of Allegiance in a school setting took place on October 12, 1892, in celebration of the 400th anniversary of Christopher Columbus's arrival in the Americas. Students in public schools across the United States recited the pledge as part of the Columbus Day festivities. Over time, the Pledge of Allegiance became a regular practice in American schools, and it underwent several revisions, most notably the addition of the phrase "under God" in 1954.
