Most New World countries abolished slavery in the 19th century; for example, Haiti 1794, Canada 1803, Mexico 1829, the U.S. 1865, and Brazil 1888. Surprisingly, slavery continued to be legal in Saudi Arabia until 1962, and in Mauritania (north of Senegal) until 1980. Around the world, various kinds of de facto slavery continue to exist today, in spite of the abolition laws. According to the U.S. State Department, somewhere between 600,000 and 800,000 people are trafficked -- by force or coercion -- across international borders every year. Between 14,500 and 17,500 of those people are sold into the United States. There are many different kinds of human trafficking -- forced servitude, labor coercion and fraud, sexual slavery and child slavery. The majority of the captives are women and children, although adult men are forced or coerced into labor as well.
