The Jesuits were never evil. But what they had built in Paraguay was incompatible with the colonial project in Argentina and Brazil. By converting the native peoples of Paraguay to Christianity, organizing them within their missions, arming them with musket, sword, and spear, training them in horsemanship, marching, and drill they had created a native militia. Beyond this they had at the behest of the Spanish crown established missions in Baja California and were about to go into Alta California. The Spanish crown grew fearful that Alta California could become a new Paraguay. The Jesuits were removed and replaced with Franciscans. Alta California would be colonized, but the crown would also fund the creation of Presidio military districts, both to defend the territory and in an attempt to keep the native Californians from becoming armed. Ultimately of course the christian native Californians were armed at the discretion of the Californios to protect their ranchos from non-christian native Californians.
