The Beatles' breakup was a gradual process that culminated in John Lennon's decision to leave the group in 1970. Tensions had been building since the death of their manager in 1967 and escalated during the recording of the White Album. Lennon's solo releases and the Plastic Ono Band's debut marked the end of the Beatles, with Paul McCartney confirming the split in April 1970. Legal battles ensued, and each member pursued their solo careers, ultimately leading to the dissolution of the iconic band.
