Pledge of Allegiance was read publicly for the first time in 1892. Francis Bellamy wrote it so that people could declare their patriotism. It has undergone four changes, and it was formally adopted by Congress in 1942.
Pledge of Allegiance was recited in schools for the first time in 1892. Francis Bellamy wrote the oath in two hours, but previously he had devoted years to developing the concept. The pledge has been modified, and four states, Vermont, Wyoming, Hawaii, and Iowa, do not require the oath in schools.
