Could the disappearance of roanoke colony be considered a genocide?
As others have said, Roanoke colony disappearance can't be proven a genocide. But you might want to move a bit farther north, and a little bit later, and look at the Mystic Massacre. As part of the Pequot War, the tribe was essentially wiped out. http://en.wikipedia.org/wiki/Pequot_War Of those spared from death, they were sold into slavery and many were shipped off to the Caribbean (which basically was a death sentence, because the mortality rates were so high). Some few were enslaved by the colonists' Indian allies, which gave them a better chance for survival. This will fit the bill, is easy to research, and is a horrifying and interesting story. I think your teacher will appreciate this. Good luck!
Why is Roanoke called the Lost Colony? What is the story behind it?
Ask Wikipedia. Roanoke, VA is NOT the lost colony. That was on the Atlantic coast, not in the Blue Ridge mountains where Roanoke, VA is located.
If Colombus discovered the Americas for Europe in 1492, why did the first colony (Jamestown) not get established until 1607, over 100 years later? Did Spain really not establish a single settlement in that 100-year headstart?
You mention Jamestown, but this was an English colony. Columbus was an Italian working for the Spanish crown, so he had nothing to do with Jamestown.Columbus first landed in the Caribbean, and immediately claimed the islands of Cuba, Hispaniola and others for the Spanish crown, and any other lands he came across in his next three voyages, which included the mainland of central and South America.The Spanish empire in the Caribbean and Central and South America grew vast, prosperous and powerful long before Jamestown was even a conception. The mighty Aztec, Maya and Inca civilisations were all obliterated in a genocidal frenzy at the cost of millions of lives before Sir Walter Raleigh, the founder the first English colony was even born.Furthermore, it was for the purposes of raiding Spanish ships transporting gold looted from the well established Spanish New World colonies that the English colonies of Virginia were first conceptualised: a base for state sanctioned piracy against those very successful Spanish colonies.So yes, Spain did have a 100 year head start on the colonisation of America, they just weren't particularly interested in the northern bit for one very simple reason — there was no gold there.
What would of happened if the Native Americans never saved the English settlers from starvation?
The idea that the English didn’t know how to farm is truly stupid. Now, the Pilgrims weren’t knowledgeable about agriculture, this is true. They literally expected God to provide for them. They were not, however, the first nor the most successful English speakers in North America. The Virginia colony was older, better established and had already fought off multiple treacherous attacks by the Powhatan tribes before Plymouth colony was established. The tribes around Massachusetts did help the English settlers there, but the next wave of English there included indentured servants who were far more knowledgeable about agriculture than the stone age denizens of America.
