Explanation

Every second grader knows how to pledge allegiance to the flag, but do you think they realize when they place their right hand over their hearts that they're expressing loyalty to what we call the "Red, White, and Blue"? You can pledge your allegiance to a flag or swear your allegiance to a government or cause. Either way you're expressing your commitment and devotion in the firmest sense of the word. The liege in allegiance comes from the Old French word meaning "lord and master," which is who you would have been swearing your allegiance to if you'd been a servant in France centuries ago.
