What is the historical significance of the 1917 Constitution for Mexico's political system?

• A. It established land reform, civil liberties, labor rights, and a centralized institutional structure; subsequent amendments redefined federalism, rights, and powers.
• B. It created a monarchic system with absolute rule.
• C. It was mostly symbolic with no policy impact.
• D. It established a federal system with no civil liberties.

Answer: (A)

The 1917 Constitution anchors Mexico's modern political system by embedding social rights, land reform, and a redefined state structure within a federal framework. It enshrined important changes that transformed how the state interacts with people and the economy: land reform through Article 27 redistributed land to peasants and promoted collective ejidos, reshaping rural power dynamics; labor rights and protections for workers through Article 123 gave unions a formal voice and set standards for working conditions, hours, and wages; civil liberties and education reform, along with church–state separation, established a more active, rights-based role for the state in social life and public institutions. While the constitution preserves federalism, its early decades expanded the state’s capacity to implement social and economic policy, a pattern that later amendments reinterpreted or refined as Mexican politics evolved. The option that emphasizes these elements is the best fit, and the other choices misstate the document’s impact by suggesting monarchy, insignificance, or the absence of civil liberties.
