Things have changed for citizens in Mexico since the 1917 Mexican revolution. The Mexican Constitution may have helped with this because in 1917 a new legal structure was established in the Constitution and it reversed the principle established under Porfirio Díaz that gave absolute property rights to individuals. In article 27 of the Mexican Constitution, gave the state the power to take over owners land and gave the State subsoil rights. Following a brief civil that lasted until 1920, Mexico finally was able to enjoy a period of gradual agricultural, social and political reforms. From 1920 and well onto the year 2000, Mexico was ruled by the reformists who emerged victorious from the Revolution and their successors in the Partido Revolucionario
