Carlo I Tocco
Muriki or Maurice Spata (, ; ) was the ruler of Arta from late 1399/early 1400 until his death in 1414 or 1415. Maurice's reign was dominated by his wars with Carlo I Tocco. Maurice was able to defend his capital of Arta, but despite some victories failed to prevent the fall of Ioannina to Tocco. As a result, his brother Yaqub Spata who succeeded him was defeated in October 1416, ending the Despotate of Arta.
