The Taifa of Matah is the real port of Lisbon, not Lisbon, silly Christians. They are a rich and wealthy taifa who pay most of their excess income to the Moors, which they are not too happy about, but they get to have no army so that's a pretty cool deal. They have poor relations with the city-state of Lisboa, and wish to annex them, but don't want to cause the entire peninsula to erupt into a war with all of the Christian kingdoms against the Islamic taifas. Their economy is very rich, with standards of living rivaling the Burgundians.
