Final answer:
The concern regarding James II was his Catholicism and absolutist rule which led to the Glorious Revolution where he was replaced by William of Orange, who was married to James's Protestant daughter and was in line for the throne. Queen Elizabeth I balanced expansion with maintaining power against Spain.
Step-by-step explanation:
The concern that those in England and her colonies maintained about James II primarily revolved around his perceived Catholic sympathies and his disregard for Parliamentary authority, which were seen to threaten the Protestant establishment and political balance. When it comes to William of Orange, it is indeed true that he was married to James II's daughter, Mary, and was also in line for the throne of England. In fact, William's claim to the throne, combined with his marriage to Mary, who was a Protestant, made him a key figure in the Glorious Revolution of 1688 in which James II was deposed.
Queen Elizabeth I's reign is noted for her diplomatic balance, encouraging the adventuring of English privateers like Francis Drake, and blocking Spain's efforts to spread Catholicism, without committing to large-scale colonization efforts as long as the Spanish threat loomed closer to home. Her reign was characterized by the growth of English maritime power and a cautious approach to expansion in the Atlantic World.
