In 1609, two years after English settlers established the colony of Jamestown in Virginia, the Dutch East India Company hired English sailor Henry Hudson to find a northeast passage to India. After unsuccessfully searching for a route above Norway, Hudson turned his ship west and sailed across the Atlantic. Hudson hoped to discover a "northwest passage," that would allow a ship to cross the entirety of the North American continent and gain access to the Pacific Ocean, and from there, India. After arriving off the coast of Cape Cod, Hudson eventually sailed into the mouth of a large river, today called the Hudson River. Making his way as far as present-day Albany before the river became too shallow for his ship to continue north, Hudson returned to Europe and claimed the entire Hudson River Valley for his Dutch employers.
