The Beatles, an iconic British rock band that rose to fame in the 1960s, broke up in 1970, marking the end of an era in music history.
Step-by-step explanation:
The popular all-male band from Britain that broke up in 1970 is The Beatles. They started their journey in 1960 and quickly became pivotal figures in suburban youth culture during the mid-1960s.
