Why did the colony fail in the Roanoke Expedition?
The Roanoke Colony failed due to a combination of factors, including:
1. Conflict between colonists and Indians: The initial voyage of the colonists was met with skepticism by the local Indian communities who believed that the colonizers were here to take their land. This resulted in several conflicts, leading to the death of some colonists. 
2. Disease: In the summer of 1588, an outbreak of smallpox killed many members of the colony, greatly reducing its number. 
3. Incompetence: The leadership of the colony was weak, resulting in poor decision-making and lack of resources. Some decisions were made based on inaccurate information or personal biases.
4. Distance from home: The colonists were far away from their families and support networks, which contributed to the loss of morale and motivation.
5. Natural disasters: A series of natural disasters such as earthquakes and hurricanes also negatively affected the community, making it difficult for them to survive and thrive. 

Overall, the Roanoke Colony failed because of a combination of conflict between settlers and Native Americans, disease, poor leadership, distance from home, and natural disaster.
