William III of England [SEP] War in Europe
William continued to absent himself from Britain for extended periods during his Nine Years' War (1688–1697) against France, leaving each spring and returning to England each autumn. England joined the League of Augsburg, which then became known as the Grand Alliance. Whilst William was away fighting, his wife, Mary II, governed the realm, but acted on his advice. Each time he returned to England, Mary gave up her power to him without reservation, an arrangement that lasted for the rest of Mary's life. After the Anglo-Dutch fleet defeated a French fleet at La Hogue in 1692, the allies for a short period controlled the seas, and the Treaty of Limerick (1691) pacified Ireland.
