The Treaty of Brétigny would not, as hoped, put an end to the conflict that would come to be called the hundred years war, but it did represent a significant change in the conflict. What is perhaps most interesting, however, is that the treaty did not result from a military victory by one side or the other. Rather, three weeks earlier, the course of European history had been changed by a hail storm.
The Reconquista, or Christian reconquest of Iberia, took nearly 800 years. The fighting did not come without great attempts by Muslim powers across the strait trying to reestablish their presence in mainland Europe. The last gasp of that effort came in the 1330s, when the powerful Marinid sultanate of what is modern Morocco invaded in an attempt to reverse Christian gains and secure the perilous position of the Sultanate of Granada.
