The term "tide of history" refers to a broad, long-term trend or movement that is often difficult to resist or change. It represents an overarching force or current that carries people and events along with it, much like how tides are influenced by the gravitational pull of the moon and carry water in and out of coastal areas. In a historical context, this phrase can be used to describe major shifts in societies, cultures, economies, politics, or technologies that seem to happen naturally and cannot easily be controlled or stopped by individuals or groups.
