Carnival season 2018 is underway across Europe and the Americas. These pre-Lent festivals, often a blend of local pagan and Catholic traditions, usher out the winter and welcome in spring. The largest and most famous—the Carnival in Rio de Janeiro, Brazil—took place over the past few days. Gathered here are images of carnivals around the world, including images from Brazil, Portugal, Hungary, Bolivia, Haiti, Spain, Italy, and more. Depending on available photos, there may be a follow-up post later this week with more from Mardi Gras and other celebrations.
