The resources of the Spanish Hapsburg empire were drained by European wars that lasted from 1621 until the 1659 Treaty of the Pyrenees with France. Under the circumstances, Spain could not continue to underwrite the increase in the Indian fund that had helped make it possible to expand into new provinces and guarantee the fidelity of older ones. After 1635 the gasto de indios, along with the situado for soldiers and Franciscans, began falling into arrears, with serious consequences. The governor employed the unpaid soldiers on his personal business, the friars spoke of abandoning their posts (Francisco Menendez Marquez I and Horruytiner, 1646a), and Indians long since pacified began to show signs of restlessness.
