Sir Walter Raleigh’s colony in North Carolina failed

Explanation:

The first English expedition tasked with colonizing the North American coast was headed by Sir Richard Grenville, a further relative of the famous English seafarer, Sir Walter Raleigh. The ships arrived on the coast of present-day North Carolina in early July 1585. Grenville and his men established a colony in the northern part of Roanoke Island. It was the first English colony in North America.

Unfortunately, the relations between the English colonists and the American natives, i.e. the Indians, began to deteriorate very quickly. The colonists lived in constant fear of attack by Native American tribes, who did not look favorably upon the newcomers. This situation made it difficult to supply the necessities of life, so that next year Grenville was forced to sail back to England to supply supplies.

However, when he returned he found a completely deserted colony. The colonists left almost no trace behind. There was no sign of violence or robbery anywhere. No graves were found nearby. All the forts and houses were dismantled, indicating that the colonists were not in a hurry at the time they decided to leave the colony. It looked like they had left her peacefully for some reason.

when world war i broke out across europe in 1914, president woodrow wilson proclaimed the united states would remain neutral, and many americans supported this policy of nonintervention. however, public opinion about neutrality started to change after the sinking of the british ocean liner lusitania by a german u-boat in 1915; almost 2,000 people perished, including 128 americans. along with news of the zimmerman telegram threatening an alliance between germany and mexico, wilson asked congress for a declaration of war against germany. the u.s. officially entered the conflict on april 6, 1917.
