England signed the Treaty of Nonsuch with Dutch protestant rebels in August 1585.
The Treaty of Nonsuch made that England would pay for an army of 7400 soldiers, commanded by Robert Dudley, to work with the rebels and fight the Spanish
While Dudley wanted to completely end Spanish rule in the Netherlands, Elizabeth wanted the Netherlands to be like it was in 1548, under Spanish control with some freedoms
While Dudley could disrupt Spanish forces in the Netherlands, he could not defeat Parma's army
Dudley stopped the Spanish from capturing Ostend, a deep water port in the English channel, which could allow the Spanish armada to join with the Duke of Parmas army
Alba stayed in the Netherlands until 1573, until he was so harsh even loyalists did not support him. He was replaced with Parma in 1578
The Spanish were preparing for the Armada since January 1586
Between the 19th and 22nd of April, Drake attacked a major Spanish naval port and destroyed 30 ships and many supplies.
The attack between the 19th and 22nd of April was called the 'singeing of the King of Spains beard
The disruption by Drake caused the armada to be a year later than planned, giving Britain more time to prepare
