Royal history in Greenwich How did the campaign begin? The killing of Mary Queen of Scots, ordered by Elizabeth, was the final straw for Philip II in the religious tensions between the two countries. The turning point came following the execution of Mary Queen of Scots – Spain’s Catholic ally. Plans for invasion accelerated however in 1587. Meanwhile, Walter Raleigh had twice tried - unsuccessfully - to establish an English colony in North America. This included Sir Francis Drake's burning of over 20 Spanish ships in the port of Cadiz in April 1587. English sailors deliberately targeted Spanish shipping around Europe and the Atlantic. Spain's empire was coveted by the English, leading to numerous skirmishes between English pirates and privateers and Spanish vessels. The Spanish saw England as a competitor in trade and expansion in the ‘New World’ of the Americas. Years of religious and political differences led up to the conflict between Catholic Spain and Protestant England.
