Mary of Sicily

From Wikipedia, the free encyclopedia

Mary of Sicily (c 1362—1402), Queen of Sicily, was the daughter and heir of Frederick III "The Simple" by his first wife Constança of Aragon.

As she was very young at the time of her father's death in 1377, her government was effectively taken over by four baronial families who styled themselves "vicars."

In 1390 Mary was taken to Aragon where she was married to Martin "The Younger", the grandson of Peter IV of Aragon. In 1392 Mary and Martin returned with a military force and successfully defeated the opposing barons, ruling jointly until Mary's death in 1402. At that time, Martin repudiated the Treaty of 1372 and ruled Sicily alone.
