Sacralizing the Landscape   

San Ysidro Feast Day, May 15, 1840, Taos, Nuevo México—Two centuries before this feast day, Spanish soldiers, settlers, and Catholic missionaries colonized large parts of these Indigenous homelands. Mexico's war for independence finally ended Spain's rule in 1821. But Catholicism endured in Hispano villages and coexisted with other practices in Native pueblos.   

Survival in these dry lands of northern Mexico depended on irrigation acequias and communal cooperation. Catholics believed it also required prayer and saintly intercession. Every May, they asked San Ysidro, the patron saint of farmers, for rain. Bearing the saint aloft—in whose representation resided God’s will—they showed him their fields and sought his blessing for bountiful water and crops.

In this remote region, daily care for the people’s well-being fell to local priests, such as Padre Antonio José Martínez, and lay leaders, including the “Penitente” brothers of the Hermandad de Nuestro Padre Jesús Nazareno (Brotherhood of Our Father Jesus the Nazarene). Under their ministrations and guidance, a locally distinctive Catholicism developed, reflecting the needs and aesthetics of the land and people.  

Eight years after this feast day, the US–Mexico War turned these lands into US territory.

San Ysidro Feast Day Procession  

The feast day starts the previous night with prayers. At daybreak, the hymn to the dawn welcomes both the sun and Christ, the son of God, to the world. Mass is held, and the villagers begin their procession. A young person often leads the way, bearing a cross followed by a line of people with San Ysidro and his porters bringing up the rear.     

US–Mexico War 
1846–48
   

The US desire to expand into Mexican lands sparked war between the two countries. Senator Daniel Dickinson from New York argued for the war by claiming expansion as the nation’s divinely ordained destiny.    

“We have not yet fulfilled the destiny allotted to us. New territory is spread out for us to subdue and fertilize; new races are presented for us to civilize, educate and absorb.”  

Massachusetts minister Theodore Parker argued against the war but similarly supported US expansion.    

“Before many years, all of this northern continent will be in the hands of the Anglo Saxon race. Could we have extended our empire by trade, by the Christian arts of peace, it would be a blessing. But we have done it in the worst way—by fraud and blood.”    

The Treaty of Guadalupe Hidalgo ended the US–Mexico War (a.k.a “Mexican–American War”) in February 1848.
