a. Henry VI/Edward IV
Explanation:
The War of the Roses was a civil war that intermittently confronted the members and supporters of the House of Lancaster against those of the House of York between 1455 and 1487. Both families sought the throne of England, by common origin in the House of Plantagenet, as descendants of King Edward III. The name «War of the Two Roses» or «War of the Roses», in allusion to the emblems of both houses, the white rose of York and the red one of Lancaster, was a product of Romanticism.
The war was mainly between the members of the landed aristocracy and armies of the feudal lords. The support for each of the sides depended to a large extent on dynastic marriages among the nobility. The patriarch of the house of Lancaster, Juan de Gante, had as first title the one of count of Richmond, the same that Enrique VII would hold at the end of the war. The leader of the house in York was Edmund de Langley, who held the Lordship of Cambridge. Later, during the reigns of the Tudors and the Stuarts, Richmondshire and Cambridgeshire would become main foci of recusers and Puritans, respectively. It should be noted that the fight between the factions lasted beyond Enrique's time, as the monarchs who followed him promoted the continuity of the confrontations.
The war of the Two Roses caused the extinction of the Plantagenet and greatly weakened the ranks of the nobility, in addition to generating great social discontent. This period marked the decline of English influence on the European continent, the weakening of the feudal powers of the nobles. On the other hand, the growth in influence of the merchants and of the centralized monarchy under the Tudors. This war marks the end of the English Middle Ages and the beginning of the Renaissance.
