After the Treaty of Perth, the Island passed between Scottish and English claimants. Alexander III of Scotland, Edward I of England, Robert the Bruce — overlords changed but Tynwald continued to meet. Edward III's 1333 renunciation formally recognised Mann as an independent kingdom. William le Scrope was inaugurated at Tynwald in 1393 and executed six years later. Henry IV claimed the Island by right of conquest. The Percy grant of 1399 and the Stanley grant of 1405 brought the dynasty that would hold the Island for three and a half centuries.
