The Pledge of Allegiance

 On October 12, 1892 that the Pledge of Allegiance was recited en masse for the first time, by more than 2 million students. It had been written just a month earlier by a Baptist minister named Francis Bellamy, who published it in Youth's Companion and distributed it across the country. It was recited on this day to celebrate the 400th anniversary of Columbus's arrival in the Americas. It was slightly shorter in its 1892 version: "I pledge allegiance to my flag and the Republic for which it stands — one nation indivisible, with liberty and justice for all."

After that, it got revised twice, and both revisions made the Pledge wordier. The first was in 1923, when it was changed from "my flag" to "the flag of the United States of America." This change was made to ensure that immigrants were pledging to the American flag and not the flags of their home countries. The second change was to add the words "under God." A few determined preachers worked for years to get it changed, but it wasn't until 1954 that it was amended. President Eisenhower attended a sermon by the Reverend George Docherty, who said: "Apart from the mention of the phrase, 'the United States of America,' this could be a pledge of any republic. In fact, I could hear little Muscovites repeat a similar pledge to their hammer-and-sickle flag in Moscow with equal solemnity." Eisenhower was convinced and within a few months the Pledge was amended to include "under God" as a way to distinguish this country from the Soviet Union.  (from "The Writer's Almanac)
