The Plantagenets were a royal family that ruled England in the Middle Ages. Schoolbooks often date the main line from 1154, when Henry II became king, to 1399, when Richard II lost the throne. Henry II and Richard II belong in that stretch. Richard III is the messy part of the tidy dictionary list: he was of the same wider family, but he was king much later, from 1483 to 1485, after two branches of that family — Lancaster and York — had already spent years fighting each other. People still call the whole clan Plantagenets. The name is a history-book word. You will see it in museums and textbooks, not in daily talk.
