Some haciendas were plantations, mines or factories. In 1709, Azcapotzalco was formed by 27 communities, divided into six haciendas and nine ranches. These enterprises did lead indirectly to the development of landed estates or haciendas. At its peak, there were about 300 pulque haciendas. They include places such as old mining haciendas, archeological sites and state parks. But the center of each of these pulque haciendas is the tinacal. An Indian army gathered at Zontehuitz then attacked various villages and haciendas. This valley is filled with tequila haciendas, archeological sites and modern distillation facilities. Slavery and serfdom was abolished on the haciendas. Their attacks on towns and haciendas continues well into the late 19th century. Other important industries were the haciendas and mercantile activities in the main cities and ports. Quite a number of black slaves also worked in the "haciendas" of the grassy llanos. The town now known as Zihuatanejo was a fishing village, surrounded by large haciendas. Many peasants were subsequently forced into debt peonage ("peonaje") on the "haciendas". The Mexican Revolution led to the loss of production of both haciendas and factories.
