The funds did not belong in law to the Inquisition. That body collected them and turned them over to the king, who granted them back again. [Sidenote: Financial administration.] The new Castilian and Aragonese states required greatly increased funds and a royal army, and both of these matters received the careful consideration of Ferdinand and Isabella. In financial affairs their activities were twofold: to procure more revenues; and to bring about greater economy in their collection and administration. The revocation of earlier land grants was one measure productive of income, since the taxes from them now went to the crown rather than to the lords. Two sources of revenue of a religious character were procured by papal grant. One of these was the _cruzada_, or sale of indulgences, based on the crusade (_cruzada_) against the Moslems. Designed for a temporary purpose it became an enduring element in the royal income. The other was the _diezmo_, or tithe, presumably for the same objects as the _cruzada_, although it too was diverted to other uses. Great attention was paid to the administration of the remunerative _alcabala_, and to stamp taxes and customs duties. The treasury department as a modern institution may be said to date from this era. In addition the Catholic Kings corrected abuses in the coinage of money. The final result is shown in the increase in the revenues from about 900,000 _reales_[54] in 1474 to well over 26,000,000 in 1504. Expenses were so heavy, however, that more than once a resort to loans was necessary. [Sidenote: Modernization of the army.] [Sidenote: The royal navy.]
