When did bebop jazz start and end?

Bebop jazz emerged in the early 1940s, becoming prominent around 1945. It marked a significant departure from the big band swing era, focusing on complex melodies and harmonies, improvisation, and smaller ensembles. While it continued to influence jazz in the following decades, its peak period is generally considered to have ended by the early 1950s, giving way to styles like cool jazz and hard bop.
