Which city gave its name to the Yorkist dynasty?

The city of York gave its name to the Yorkist dynasty.

The House of York was named through the title Duke of York, held by Edmund of Langley, the fourth surviving son of Edward III. His descendants formed the Yorkist branch of the Plantagenet royal family, so the dynasty’s name ultimately refers to the English city and its associated duchy.

The Yorkists claimed the English throne through a complicated line of descent from Edward III. Their strongest hereditary claim came through Richard of York’s marriage to Anne Mortimer, which connected the family to the descendants of Lionel of Antwerp, Edward III’s second surviving son. This claim helped fuel their conflict with the Lancastrian branch.

Three Yorkist kings ruled England: Edward IV, Edward V, and Richard III. Their rivalry with Lancaster produced the Wars of the Roses, which ended when Henry Tudor defeated Richard III at Bosworth in 1485. The name York can therefore refer to the city, the duchy, the dynasty, or the political faction. It is not simply a family surname in the modern sense; it is a territorial dynastic label.
