A Miura bull is a Spanish fighting bull bred from the lineage of the Miura Cattle Ranch located in the province of Seville Spain. The ranch originally belonged to Don Eduardo Miura Fernández and is known for producing large and difficult fighting bulls. A Miura bull first debuted in Madrid on April 30 1849. The Miura line traces its roots to five historic Spanish bull breeds namely the Gallardo Cabrera Navarra Veragua and Vistahermosa-Parladé.
