SOLCHAGA, Miguel (sole-tehah'-gah), Mexican clergyman, born in Queretaro in 1674; died in Durango in 1718. He entered the Society of Jesus in 1689, and, after finishing his studies, was sent as professor of theology to the College of Durango. When General Gregorio Mendiola was sent in 1715 to subdue the Indians of the Nayarit mountains, between New Biscay and New Galicia, Bishop Tapiz appointed Solchaga spiritual director of the expedition, and as such the latter brought it about that the cacique Tonatiuh, of Nayarit, went in 1718 to Mexico to make a treaty with the viceroy. But on account of sickness Solchaga returned in the same year to Durango, where death overtook him before he could publish his description of the expedition. It was afterward printed in Spain under the title "Carta Relacion de la entrada de la Expedicion Espanola en el Nayarit" (Barcelona, 1754).
