Final answer:
Upon becoming King, James I significantly worsened Sir Walter Raleigh's already declined position, eventually leading to Raleigh's loss of colonial rights and ceasing his role in North American colonization.
Step-by-step explanation:
James I's Treatment of Sir Walter Raleigh
Following the death of Queen Elizabeth I and the accession of King James I, Sir Walter Raleigh's fortunes declined significantly. After Raleigh had fallen out of favor with Queen Elizabeth for marrying one of her ladies without her permission, his position further deteriorated under King James. Raleigh's efforts in pioneering English colonization, particularly his investments in the Roanoke Island settlement, were jeopardized by his imprisonment and the ultimate loss of control over his North American ventures during James I's reign.
Raleigh was once a celebrated courtier and favorite of Elizabeth I, known for his adventures at sea as a privateer and for his attempts to establish an English colony in North America. His marriage to Elizabeth Throckmorton and subsequent imprisonment in the Tower of London marked the beginning of his decline. With James I's succession, Raleigh's situation worsened, and he was stripped of his colonial rights, effectively ending his role in the English colonization of North America.
