Occasionally the Church gave trouble - the presence of foreign priests was complained of; attempts to evade the law prohibiting conventual life were detected and foiled (1891, 1894); and there were Indian risings, repressed sometimes with great severity, among the Mayas of Yucatan, whose last stronghold was taken in 1891, and the Yaquis of Sonora (1899-1900).
Since the Spanish conquest, the Mayas have clung to the semi-barren, open plains of the peninsula, and have more than once revolted.
The Mayas had a calendar of 360 days, with intercalary days; this solar year was intersected by their sacred year of twenty weeks of thirteen days each, and these assembled in bewildering cycles.
The Mayas have left no r cord of their institutions or of the causes of their decline, beyond what may be deduced from their ruined structures.
Other remains which bear witness to tlae civilization of, the Mayas are the paved highways and the artificial reservoirs (aguadas) designed for the preservation of water for towns through the long dry season.
