“Under God” was added to the Pledge during the communist era as the US response to the USSR stating their leader had command over everyone, and the effort was to abolish religious worship. The US response was to add “Under God” to the Constitution to emphasize Americans–everyone for that matter–had unalienable rights that overruled any human leader.
The Pledge of Allegiance was written in August 1892 by the socialist minister Francis Bellamy (1855-1931). It was originally published in The Youth’s Companion on September 8, 1892. Bellamy had hoped that the pledge would be used by citizens in any country.
In its original form it read:
"I pledge allegiance to my Flag and the Republic for which it stands, one nation, indivisible, with liberty and justice for all."
In 1923, the words, “the Flag of the United States of America” were added. At this time it read:
"I pledge allegiance to the Flag of the United States of America and to the Republic for which it stands, one nation, indivisible, with liberty and justice for all."
In 1954, in response to the Communist threat of the times, President Eisenhower encouraged Congress to add the words “under God,” creating the 31-word pledge we say today. Bellamy’s daughter objected to this alteration. Today it 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."
As you will see in Alex’s post the Founders did not have a Pledge. The National Anthem wasn’t adopted as such until 1931, although it was written in 1814.
The founding Fathers already knew our new nation was “under God” as they credited him with endowing us with our rights and ordaining and establishing our constitution, which enumerates them…
