The phrase "Index of the Black Prince" is not the title of a single, famous historical document. Instead, it functions as a conceptual portal—a curated entry point into the life, legacy, and enduring mystery of Edward of Woodstock (1330–1376), better known as the Black Prince. An "index" of this figure would be a structured guide, cross-referencing the key places, events, artifacts, and controversies that define one of the most romanticized and brutal figures of the Hundred Years' War.
