Peter Minuit became Director of the New Netherland in 1626 and made a decision that greatly affected the new colony. Originally, the capital of the province was to be located on the South River, but it was soon realized that the location was susceptible to mosquito infestation in the summer and the freezing of its waterways in the winter. He chose instead the island of Manhattan at the mouth of the river explored by Hudson, at that time called the North River.
