Interpreters have sometimes played crucial roles in history. A prime example is La Malinche, also known as Malintzin, Malinalli and Doña Marina, an early-16th-century Nahua woman from the Mexican Gulf Coast. As a child she had been sold or given to Maya slave-traders from Xicalango, and thus had become bilingual. Subsequently given along with other women to the invading Spaniards, she became instrumental in the Spanish conquest of Mexico, acting as interpreter, adviser, intermediary and lover to Hernán Cortés.

What region did La Malinche hail from?
