Due to the situation in Iberia, Charles believed he needed a virtually full-time army—one he could train intensely—as a core of veteran Franks who would be augmented with the usual conscripts called up in time of war. To train the kind of infantry that could withstand the Muslim heavy cavalry, he needed to pay them so their families could buy the food they would have otherwise grown. To obtain money he seized church lands and property, and used the funds to pay his soldiers. It was Charles' creation of a system whereby he could call on troops year round that gave the Carolingians the first standing and permanent army since Rome's fall in the west.
