The Treaty of Nonsuch signed by Elizabeth I of England and the Dutch Rebels.

The Treaty of Nonsuch was signed on 10 August 1585 by Elizabeth I of England and the Dutch rebels fighting against Spanish rule. It was the first international treaty signed by what would become the Dutch Republic. It was signed at Nonsuch Palace, England.

Elizabeth I was Queen of England and Ireland from 17 November 1558 until her death in 1603. She was the last and longest reigning monarch of the House of Tudor. Her eventful reign, and its effect on history and culture, gave name to the Elizabethan era.

The Eighty Years' War or Dutch Revolt was an armed conflict in the Habsburg Netherlands between disparate groups of rebels and the Spanish government. The causes of the war included the Reformation, centralisation, excessive taxation, and the rights and privileges of the Dutch nobility and cities.
