The primary reason to say the Pledge of Allegiance, especially among children in school, is to instill a sense of patriotism and to show pride and loyalty towards the country. In addition to school children, the Pledge of Allegiance is used to open congressional sessions and is also used in various government meetings at local events and in meetings among private organizations.
Another important component of the pledge is the amount of history it contains as the Pledge of Allegiance has been an active part of American society for up to a century. The Pledge of Allegiance was initially composed by Francis Bellamy in 1892 and formally adopted by Congress in 1942. The pledge's official name, The Pledge of Allegiance, was officially adopted in 1945.
