Police in england are an evolution of how the King's peace has been enforced, starting, very simplified, from when the King himself enforced it in very early days to delegating it to members of his court and his sheriffs, and ultimately to localities and special departments of the modern day. Cities did not generally have a "police department" but they had the sheriff and whoever the sheriff commanded into service to enforce the peace. As populations have increased the enforcement of these duties have evolved to be taken on by more local organizations that are modern police departments.
