What conflict was characterized by the struggle between the Lancaster and York families for control over England?

The conflict characterized by the struggle between the Lancaster and York families for control over England is known as the Wars of the Roses. This series of dynastic conflicts occurred during the 15th century, primarily from 1455 to 1487, and was marked by a series of battles for the English throne. The name "Wars of the Roses" comes from the symbols associated with the two rival factions: the red rose representing the House of Lancaster and the white rose representing the House of York.

This conflict is significant because it encapsulated not only a power struggle between noble families but also various political, social, and economic factors at play in England during that time. The Wars of the Roses ended with the rise of the Tudor dynasty, particularly Henry VII, following the defeat of Richard III at the Battle of Bosworth Field in 1485. This pivotal moment in English history laid the groundwork for the subsequent Tudor rule and major shifts in the monarchy, governance, and England's relationship with Europe.
