In the late 15th century, England was still reeling from its dynastic wars first with France and then among its ruling families back on home soil. The great victories against France in the Hundred Years' War were in the past; only the small enclave of Calais in northern France remained of the vast continental holdings of the English kings. The War of the Roses—the civil war between the houses of York and Lancaster—had ended with Henry VII's establishment of the House of Tudor, the new ruling dynasty of England. The ambitious naval policies of Henry V were not continued by his successors, and from 1422 to 1509 only six ships were built for the crown. The marriage alliance between Anne of Brittany and Charles VIII of France in 1491, and his successor Louis XII in 1499, left England with a weakened strategic position on its southern flank. Despite this, Henry VII managed to maintain a comparatively long period of peace and a small but powerful core of a navy.
