Corn, or maize, has shaped the foundations of Mesoamerican civilizations for millennia. Domesticated around 9,000 years ago from a wild grass called teosinte in southwestern Mexico, maize evolved through human innovation and selection. It became a cornerstone of the region’s agricultural, cultural, and spiritual life, playing a critical role in trade, rituals, and sustenance (Cultural History of Maize, n.d.). We explore maize’s journey from its origins to its spread through exchange networks and its resilience during the colonial period (1650–1750), highlighting its enduring significance.

This is your story’s title

This story includes several of the pieces you might use in your own story–like paragraphs, buttons, separators, and more. To get started, select a section of the styling panel and make some adjustments. As you adjust different elements, you’ll see this story adjust to demonstrate how they look. Try changing the paragraph font, and see what happens to this text.

This is the title for the story credits. It uses the title font.

This is where the credit description goes; it uses the paragraph font.

Next, try adjusting the button style and see how your selection affects the button below. You’ll also notice that it uses the paragraph font for its text.

You can style your paragraph text to use bold, italics, and bold italics, so you can emphasize important text accordingly. These come pre-packaged with the fonts you’ve chosen, so there’s nothing extra you need to configure.

Quotes use the theme’s title font, but you can also choose one of several different styling options.

Your theme’s accent color is used in both quotes (see above) and separators (below). If you add an express map to your story, your drawn features will use the accent color too.

You have a few different options for separator styles; toggle between them and see how the separator above changes.
