Answer
The National Revolutionary Party (PNR), founded by Plutarco Elías Calles in 1929 after the assassination of Álvaro Obregón, sought to consolidate political stability in post-revolutionary Mexico. It aimed to institutionalize the Revolution, unite various political factions, and ensure a smooth transfer of power. The PNR dominated Mexican politics for decades, promoting economic development and social reforms while maintaining a strong grip on power.
