In 2007, while walking through the airport in Thessaloniki, Greece, evangelist and motivational speaker Christine Caine passed by a number of handmade posters with pictures of missing girls. Astounded that so many kids were missing, Caine did some research and found out that these children were trafficked.Thinking that trafficking couldn’t possibly exist in the 21st century, Caine decided to investigate further. Caine remembers reading witness reports of girls being placed on platforms and sold in auctions similar to those in 18th and 19th century America. She came by stories of newborns being sold into pedophile rings, and she decided to do something about it.In 2008, Caine and her husband founded The A21 Campaign, a nonprofit that focuses on sex trafficking in southeastern Europe. The name comes from the organization’s goal to abolish injustice in the 21st century. The campaign tries to prevent human trafficking through awareness campaigns, protects survivors in their shelters and transition homes, helps prosecute traffickers and partners with law enforcement and other bodies to end human trafficking.
