The 10th parallel is a latitudinal line situated 700 miles North of the equator. More than half of the world's 1.3 billion Muslims live along it, as does 60 percent of the world's Christians. Journalist and poet Eliza Griswold has recently returned from a seven year journey, on which she traveled between the equator and the 10th parallel. She spent time in countries like Nigeria, the Sudan, Somalia, Indonesia, Malaysia and the Philippines, and documented her journey in "The Tenth Parallel: Dispatches from the Fault Line Between Christianity and Islam."
Griswold says she sees similarities in the tensions that lie between religion and political power in these countries and the way they unfold even here in America.
