La cucaracha (the cockroach) is a Mexican revolutionary song, the chorus of which probably alludes to General Victoriano Huerta, who was called la cucaracha because of his consumption of alcohol and drugs and who allegedly could not get going without marihuana. The historical background of this popular song, which is now known throughout the world, prompted the author to give this title to her travelogue about Central Mexico and the Yucatán. All the major colonial cities of the Central Highlands did indeed play a decisive role during the Mexican revolutionary wars of the 19th century.
