When you consider the history of the chainsaw you might imagine that it's only connection to medicine would be the average of approximately 28,000 chainsaw injuries reported in the US annually. But you would be wrong. The shocking history of the mechanically driven cutting tool with teeth set on a chain deserves to be remembered.
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.
