Final answer:
Perkin Warbeck, a pretender to the English throne, was welcomed at the Burgundian Court during the reign of Henry VII in the late 15th century, amid the aftermath of the Wars of the Roses. The exact date of his welcome is not specified, but his involvement in English politics was most notable in the 1490s, with an invasion attempt in 1497.
Step-by-step explanation:
Throughout the turbulent period of the late 15th century, notable figures such as Perkin Warbeck emerged claiming rights to the English throne. Warbeck, a pretender to the English throne during the reign of Henry VII, was indeed welcomed at the Burgundian Court, because of the interest in challenging Henry's rule. The Burgundian nobility had various reasons for supporting claimants like Warbeck, including the political advantage of having a potential ally or puppet in England, especially following the ending of the Wars of the Roses.
Warbeck claimed to be Richard of Shrewsbury, Duke of York, the younger of the two sons of Edward IV, who were the famous 'Princes in the Tower', and presumed murdered. His reception into the Burgundian Court signifies the complexities of European politics, where monarchies often used pretenders as political tools. While the exact date of Warbeck's formal reception at court is not specified in the reference material provided, it is historically known that his claim was prominent in the 1490s, with his most notable invasion of England occurring in 1497. This period of political intrigue and conflict eventually subsided, and the Tudor dynasty under Henry VII strengthened the monarchy's political force in England.
