During Cárdenas' presidency, the government enacted land reform that was "sweeping, rapid, and, in some respects, innovative". He redistributed large commercial haciendas, some 180,000 km2 of land to peasants. With the powers of Article 27 of the Mexican constitution, he created agrarian collectives, or ejidos, which in early twentieth-century Mexico were an atypical form of landholding. Two high-profile regions of expropriation for Cárdenas's agrarian reform were in the productive cotton-growing region in northern Mexico, known as La Laguna, and in Yucatán, where the economy was dominated by henequen production. Other areas that saw significant land reform were Baja California and Sonora in northern Mexico, his home state of Michoacán and Chiapas in southern Mexico.
