Definition & Meaning of "eat humble pie"in English

What is the origin of the idiom "eat humble pie" and when to use it?

The origin of the idiom "eat humble pie" can be traced back to medieval times in England. During that time, a dish called "umbles" was commonly eaten by lower-class people. "Umbles" referred to the edible organs of an animal, particularly the heart, liver, and other offal. These parts were considered less desirable and were often consumed by servants, peasants, or hunters who couldn't afford the more prized cuts of meat. This expression is commonly used in personal interactions, professional settings, or even in public discourse when someone's pride or hubris has been challenged, and they are compelled to face the consequences or make amends for their actions.
