Question 18 SA-9. Here is the text (p. 168/2 to 3):

The Mexican Revolution was also in a sense a continuation of the aborted popular revolt of 1810 led by the priests Hidalgo and Morelos, which had been co-opted by the conservative elites. The 1910 Revolution broke the power of these elites, the Catholic Church, and the old-style military.

The stage for the Revolution was set by the long conservative rule of General Porfirio Díaz, who for 34 years had governed Mexico under the ideology of the Positivists. His regime boasted of many signs of material progress, but these favored the Mexican elites and the foreign investors, to the detriment of the large masses of lower class Mexicans. The economy was neocolonial, since it was based on control of Mexico's extractive industries (especially oil and minerals), by American, British and other European investors. Internally Díaz controlled Mexico through a tight alliance of the large landowners, the Church, and the military and police forces directly under his command. Each of these legs of his three-legged stool of conservative power supported each other, and the system endured, providing the stability so cherished by the Positivists and so attractive to the foreign investor.
