Born in the wake of empire, conquest and revolution, Mexico today is the most populous Spanish-speaking country in the world. Its capital city the second largest after Tokyo is bursting with 20 million people and rivals the whole of Australia in population. The story of Mexico is a story of faith and family, ritual and tradition. Mexico is home to the New World's largest Catholic Church and diocese, where 90 percent of Mexicans call themselves Catholic. Yet nothing can be less orthodox than rituals celebrating the dead or spectacles honoring their patron saint, the Virgin of Guadalupe. Deep in the heartland, the largest indigenous community in the Americas practice rituals that hearken back to ancient Mayan beliefs.
