Otumba or Otumba de Gómez Farías is a town and municipality located in the northeast of the State of Mexico, just northeast of Mexico City. Historically, this area is best known as the site of the Battle of Otumba and as an important crossroads during the colonial period where incoming viceroys ceremoniously were handed power by their predecessors. Today, it is a rural municipality undergoing changes as urbanization arrives here from the Mexico City area. However, one element from the past that is still remembered is that of burros or donkeys. During the colonial period, Otumba was an important market for the animals, and they are still culturally important. Each year, the municipality sponsors a Feria de Burros or Donkey Fair, where the animals star in fashion shows, costume contests, and races.
