Treaty of Blois (1572)

The Treaty of Blois was signed on 19 April 1572 in Blois between Elizabeth I of England and Catherine de' Medici of France. Based on the terms of the treaty, France and England relinquished their historic rivalry and established an alliance against Spain. The treaty also entailed France to be kept out of Mary, Queen of Scots and Scotland's affair with England. Elizabeth expected the defensive treaty to isolate Spain and prevent France from invading Flanders.
