Final answer:
The information provided does not specify when Edmund de la Pole left England, but it offers context about the Tudor era, during which he lived and eventually came into conflict with Henry VII.
Step-by-step explanation:
The provided information does not directly mention Edmund de la Pole, so I cannot definitively answer when Edmund de la Pole left England. However, I can offer some context about the period in which he lived. Edmund de la Pole, Earl of Suffolk, lived during the late 15th and early 16th centuries, a time marked by the tumultuous political landscape of the Tudor dynasty.
In the Tudor era, significant historical events such as the War of the Roses, the Hundred Years' War, and the start of the English overseas exploration took place. These events shaped the nation's history, but there's no specific reference to de la Pole's departure from England in the provided paragraphs. It's important to note that Henry VII, who reigned from 1485 to 1508, sought to reduce the influence of the English aristocracy, and Edmund de la Pole was a member of the aristocracy who had a contested claim to the English throne, which led to his eventual conflict with Henry VII and his departure from England.
