On December 13, 1916 one of the deadliest avalanche in history occurred, and barely made the newspapers. The White Friday avalanches were a little remembered event of the little remembered, but uniquely horrible, Italian front in the Great War.
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.
