When the Mummy, starring Boris Karloff, was released by Universal studios in 1932 it was inspired by a real event, and drew upon a mix of ideas, some new, and some very old.

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.
