"The famous "pueblo league was a legal fiction. Before the eighteenth century, the Pueblo Indians seem to have been entitled to whatever lands they habitually occupied or used. Sometime after 1700, however, they evolved the doctrine... a sort of recognized minimum right of the Pueblos. In the case of Pecos, it was a minimum indeed... In Spanish law, current use was the key. No matter that the Pecos had farmed or otherwise used more land historically, they were no longer using it in the nineteenth century."
