How did the Mexico's new constitution in 1917 aim to change Mexican life?

Answer 1

From Internet:

We consider the passage of the Constitution of 1917 to mark the culmination of the Mexican Revolution. That Constitution, still in force today almost one hundred years later, insisted on complete separation of Church and State (article 3), the division of large haciendas into ejidos, held jointly by local entities and national ownership of national subsoil (article 27), and the right of labor to organize, strike, receive compensation for workplace accidents.
