Mauritania could have been designed to be a modern-day slave state, so perfect are the conditions for entrenching this cruel habit. An artificial creation of the end of colonialism, the European-drawn, largely arbitrary borders cut across ethnic groups that are black African, black Arab or Berber, and white Arab or Berber. French colonialism rapidly centralized much of what was once a heavily nomadic population, forcing ethnic groups that had once been separated by geography to coexist and to compete. In the 1970s, widespread droughts forced many of the country's farmers and rural peoples into cities, creating new classes of destitute and jobless citizens who have been unable to adapt to this new reality. Because 50 percent of the economy is still based in agriculture, urban job opportunities are scarce. Lacking other options, faced with an economy unable to help them and an ethnic hierarchy that tells them they are worth less than their white-faced or Arab counterparts, they become slaves. Many of the displaced were children in need of a guardian. Many of those guardians became masters. The cycle repeated in the late 1980s, when an estimated 70,000 black Africans were expelled from the country, leaving behind masses of children, many of whom were enslaved.

Slavery is self-perpetuating. A first-generation slave is a desperate man, woman, or, most often, child who accepts degradation in exchange for survival. A second-generation slave knows nothing else. Though Mauritania's post-colonial struggles have perpetuated and entrenched the practice, it began generations earlier. As in Saudi Arabia, which did not emancipate its slaves until 1967, slavery was a function of extreme wealth discrepency that divided along ethnic lines between Arab and African, skin color lines between white and black, and often between sedentary and nomadic communities, the latter of which lacked recourse for recovering its children abducted into slavery. In Mauritania, the practice began with 8th century Arab colonists who took black slaves. As the number of slaves increased -- first by the ravages of European colonialism, then by the crises of the 1970s and 1980s -- the practice became the norm, which made it both too pervasive and too accepted for legislation to simply overturn.

Though a number of Mauritanians hold slaves, there is a large, popular movement in the country that finds slavery just as abhorrent as did 19th century northeastern Americans, and as does most of the world today. Several anti-slavery groups formed in the 1970s to combat (and, they hope, overturn) the practice: El Hor, Arabic for "free man"; In'itaq, Arabic for "emancipation; and SOS Esclaves, French for SOS Slaves. But their efforts to campaign against slavery have largely been stifled by the government, which has changed hands repeatedly over the past decade. Because the country's various coup-based military leaders have so feared for their own survival, they have either ignored or suppressed anti-slavery groups as dissenters and potential threats to their rule.
