The Roanoke Colony
Back in the late 1500’s, Sir Walter Raleigh received a charter from Queen Elizabeth I to colonize the New World. Being the busy explorer he was, Raleigh sent a few people in his place to find a nice place along the Atlantic coast to set up shop and start making big money for the folks back home. When they arrived in what would become America, they established the Roanoke Colony. Over the years, two different groups of settlers made their way to Roanoke, with the second group of 117 landing on Roanoke Island in 1587.
And then they promptly vanished. Because of the Anglo-Spanish War that was being waged at the time, one of the leaders of the expedition and friend to Raleigh, John White, was delayed three years in returning to Roanoke with supplies. When he finally did return, he discovered something more than a little creepy: everyone was gone. There was absolutely no trace of the settlement, as the houses had been taken down and all that remained was the word “Croatoan” carved into a nearby tree. So what did White do? He and his men decided that they didn’t want to actually, you know, search for the missing settlers (which included White’s own daughter and granddaughter). To this day, no one knows what happened to the colonists of Roanoke, all because White was, at his core, really lazy.
Good news, I found it!
