Definition of the word come together

In the 1960s, African-American activists used the phrase to call for social and political unity and change during the Civil Rights Movement. It appeared in posters, pamphlets, and rallying cries, as a call for people to come together and work towards a common cause. It's possible that Lennon, who was interested in political and social issues, came across the slogan during his travels to New York City, where hip-hop music and culture were emerging. The slogan was also popularized by the 1959 release of "Dem Bow," a ska rocksteady song by Jamaican musician KC & The Sunshine Band that contained the phrase. The meaning of "come together" in Lennon's song, however, extends beyond its origins in African-American culture. It encourages people to set aside their differences and work together towards a greater goal. The song's lyrics call for "all [to] be together," acknowledging the importance of unity in bringing about positive change. Overall, the origins of "come together" reflect the spirit of community action and activism during the turbulent social and political climate of the 1960s, as well as the wider cultural context of both American and Caribbean popular music.
