The coat of arms of Melillan spanish Regions is that of the Ducal House of Medina Sidonia, whose titular funded the military operation that seized Melilla in 1497.[1]
The crown is topped by a turret, with a male figure throwing a dagger (Guzmán el Bueno, ancestor of the first duke) in chief.[2] The top part of the coat of arms reads Præferre Patriam Liberis Parentem Decet (Latin: "It is seemly for a parent to put his fatherland before his children"), also a nod to the Guzmán el Bueno's role during the 1296 defence of Tarifa on behalf of Sancho IV of Castile. The supporters are the Pillars of Hercules and read Non Plus Ultra (Latin: "Nothing further beyond").
It is the central device of the flag of Melilla.
