The Pious Fund of the Californias is a fund, originating in 1697, to sponsor the Roman Catholic Jesuit Spanish missions in Baja California, and Franciscan Spanish missions in Alta California in the Viceroyalty of New Spain from 1769 to 1823, and originally administered by the Jesuits. It became the object of litigation between the US and Mexican governments in the 19th century, with the resolution making legal history in The Hague in 1902.
