What did the Dutch west India company establish to protect the mouth of the Hudson River?

The Dutch West India Company established Fort Amsterdam at the mouth of the Hudson River to protect its interests and trade routes in the region. Founded in 1625, the fort served as the administrative center for the company's operations in New Netherland and played a crucial role in defending against rival European powers and local conflicts. The establishment of Fort Amsterdam laid the groundwork for the future city of New York.
