The Spanish of the Yucatán: What is that?

In the years following the arrival of the Spanish in what is now called Mexico, the Yucatán Peninsula was populated by a very large group of people who spoke Maya and a significantly smaller number of Spanish speakers, descendants of the conquistadors who had arrived a generation before. The Spanish tried hard to maintain their pure bloodlines, but inevitably succumbed to the charms and the stubborn resilience of the Mayas. (Interesting historical note: the Mayas were the only indigenous people of Mexico who were never fully conquered.)
