How did the role of samurai change over time?

The role of samurai evolved significantly from the feudal era to the Edo period in Japan. Initially, they were warriors serving powerful lords, engaged in battles and protecting their territories. However, as Japan became more unified and peaceful during the Edo period, their role shifted from military service to that of bureaucrats and administrators, focusing on governance and maintaining order. This transformation also led to the development of a distinct samurai culture centered around honor, discipline, and the arts, rather than warfare.
