In the late sixteenth century, the seven northern provinces of the Netherlands fought for and won their independence from Spain as the Republic of the United Provinces of the Netherlands.

In this period the Netherlands experienced a golden age. The province of Holland was the most powerful. Holland also financed the Dutch in many wars.

There were challenges to the security, unity, and prosperity of the Dutch Republic from 1650 to 1713.
There were many challenges to security in the Dutch Republic. The Netherlands is situated around many European nations, especially Britain who at that time posed a threat.
