The melody and the chords were worked up in a November 1983 War Tour sound check in Hawaii and completed in Windmill Lane Studios during The Unforgettable Fire recording sessions. The guitar part is subtly varied through each verse, chorus, and melody, such that no riff is exactly repeated.
The song had been intended to be based on Ronald Reagan's pride in America's military power but after the lyricist Bono had been influenced by Stephen B. Oates's book Let The Trumpet Sound: A Life of Martin Luther King, Jr. and a biography of Malcolm X, these caused him to ponder the different sides of the civil rights campaigns, the violent and the non-violent. In subsequent years, Bono has expressed his dissatisfaction with the lyrics, which he describes, along with another Unforgettable Fire song "Bad", as being "left as simple sketches". He says he was swayed by The Edge and producers Brian Eno and Daniel Lanois, who played down the need to develop the lyrics as they thought their impressionistic nature would give added forcefulness to the song's feeling, particularly when heard by non-English speakers.
"I looked at how glorious that song was and thought: 'What the fuck is that all about?' It's just a load of vowel sounds ganging up on a great man. It is emotionally very articulate - if you didn't speak English language."
The song contains the erroneous reference to King's shooting as "Early morning, April 4", when it actually occurred after 6 p.m. Bono acknowledges the error and in live performances he occasionally changes the lyric to "Early evening...".
"Pride" reached #3 on the UK Singles Chart and #8 on the Dutch Singles Chart. The song was the band's first top 40 hit in the United States where it peaked at #33. It gained considerable US album-oriented rock radio airplay and its video was on heavy rotation on MTV, thus helping U2 continue its commercial breakthrough begun with the War album. It reached #1 in New Zealand, the first time a U2 single topped a country's singles chart.
Initial critical reactions to "Pride" was often negative – especially in regards to the lyrics. Robert Christgau in The Village Voice complained of "the moralism with the turn-somebody-else's-cheek glorification of Martin Luther King's martyrdom." Meanwhile, Kurt Loder of Rolling Stone wrote that " 'Pride' gets over only on the strength of its resounding beat and big, droning bass line, not on the nobility of its lyrics, which are unremarkable."

"Pride" was first played live at the fourth show of the Unforgettable Fire Tour on 2 September 1984 in the New Zealand city of Auckland. The song has been played at virtually every U2 concert since the Unforgettable Fire Tour although it was played infrequently on 2009's 360 Tour. As of 2009, it is the band's most played song with over 770 documented performances, though "I Will Follow" has likely been performed more often. Clips from Martin Luther King speeches are often shown on the various tour video screens during these performances. In 2010, in Brisbane, Australia, the final verse was changed to reflect the 30th anniversary of the assassination of John Lennon (8 December 2010).
U2 performed the song, along with "City of Blinding Lights", to upwards of 400,000 people on 18 January 2009 at the We Are One concert at the Lincoln Memorial to celebrate the upcoming inauguration of Barack Obama. At the end of the performance Bono asked the audience to sing for King's dream, saying it was "not just an American dream; also an Irish dream, a European dream, an African dream", before referencing it to the Israeli–Palestinian conflict and saying that it was "an Israeli dream, and also a Palestinian dream." The performance of "Pride" closed off with Bono quoting part of King's speech "I Have a Dream", saying "Let freedom ring! Let freedom ring! Let freedom ring! Every village, every hamlet, every state, every city. Let freedom ring!" before seguing into "City of Blinding Lights". Adam Clayton later said "We were scratching our heads going, 'How does an Irish band get invited to play at the Presidential Inauguration?' Our way in was through a song like 'Pride'. It allowed Obama's people to express the connection without being too overt. It was one of those moments where you know the world is watching, but a healthy amount of anxiety gets your mojo working."
Three music videos were made. The first was shot in August by director Donald Cammell and features opening and closing shots of the Dublin Docklands area. Two versions of this video exist; black and white and colour (sepia). The band was not satisfied with Cammell's video, and they agreed to their principal photographer, Anton Corbijn, shooting an alternative. The second video filmed in a basement near London's Heathrow Airport, it features U2 standing sternly in front of a wall under poor lighting conditions. The U2 camp was also unimpressed with this video and a third video is produced by compiling footage shot during The Unforgettable Fire recording sessions at Slane Castle. The original (black and white) Cammell video was primarily used in promotion.
