One group was Jehovah’s Witnesses, a small Protestant denomination. They believed reciting the Pledge was a form of idolatry that ran contrary to their religious beliefs. When students of that denomination got kicked out of school for refusing to say it, they sued, which led to two cases before the U.S. Supreme Court. In 1943, the Court ruled in favor of the Jehovah’s Witnesses, saying that no student could be forced to say the Pledge. This judgment on freedom of expression remains the law of the land.
Then, in 1954, during the early years of the Cold War, Congress added the words “under God” to the Pledge. Scholars say this was a way to distinguish American ideals from the “godless Communism” of the Soviet Union, which denounced religion and persecuted those who practiced it.
Many Americans have objected to the phrase. In 2004, the Supreme Court heard an argument from an activist named Michael Newdow that “under God” violates the First Amendment’s freedom from government-sponsored religion. But the Court unanimously rejected his suit on a technicality.
Still, David Hudson, a First Amendment scholar, says that the decision was seen in part as acknowledging a widespread acceptance of the Pledge—including “under God”—across the country. The Court, along with most Americans, “viewed the Pledge as more of a patriotic exercise than an advancement of religion,” he says.
But the Pledge can still serve as a lightning rod for protest. In November, a New Jersey seventh-grader named Manny Martinez made headlines by refusing to recite it—an action frowned upon in many communities. Manny said that the election of Donald Trump, whom he sees as disrespectful to women and minorities, made it impossible for him to participate in the salute to the flag.
Yet in other circumstances, the special symbolism of the Pledge is used to reaffirm America’s qualities. When then-President Barack Obama visited a mosque in Baltimore, Maryland, last year, Muslim men in skullcaps and women in hijabs stood to recite it.
“You’re part of America too,” Obama told them.
One hundred twenty-five years after its birth, the Pledge endures. “No salute is so deeply rooted in the national experience or intertwined in daily life,” write Jones and Meyer in their book, The Pledge. For many people of the United States, they write, its words capture a “fundamental sense of national identity”—what it means to be American.
