By 1860, 500,000 slaves had grown to 4 million. As long as slavery expanded, it remained profitable and powerful and was unlikely to disappear. Although complete statistics are lacking, it is estimated that 1,000,000 slaves moved west from the Old South between 1790 and 1860.[114]

Most of the slaves were moved from Maryland, Virginia, and the Carolinas. Michael Tadman, in a 1989 book Speculators and Slaves: Masters, Traders, and Slaves in the Old South, indicates that 60–70% of interregional migrations were the result of the sale of slaves. In 1820 a child in the Upper South had a 30% chance to be sold south by 1860.[114]

According to Robert Davis between 1 million and 1.25 million Europeans were captured by Barbary pirates and sold as slaves in North Africa and Ottoman Empire between the 16th and 19th centuries.[115][116] There was also an extensive trade in Christian slaves in the Black Sea region for several centuries until the Crimean Khanate was destroyed by the Russian Empire in 1783.[47] In the 1570s close to 20,000 slaves a year were being sold in the Crimean port of Kaffa.[117] The slaves were captured in southern Russia, Poland-Lithuania, Moldavia, Wallachia, and Circassia by Tatar horsemen in a trade known as the "harvesting of the steppe". In Podolia alone, about one-third of all the villages were destroyed or abandoned between 1578 and 1583.[118] Some researchers estimate that altogether more than 3 million people were captured and enslaved during the time of the Crimean Khanate.[119][120] It is estimated that up to 75% of the Crimean population consisted of slaves or freedmen.[77]

The Arab slave trade lasted more than a millennium.[121] As recently as the early 1960s, Saudi Arabia’s slave population was estimated at 300,000.[122] Along with Yemen, the Saudis abolished slavery only in 1962.[123] Slaves in the Arab World came from many different regions, including Sub-Saharan Africa (mainly Zanj),[124] the Caucasus (mainly Circassians),[125] Central Asia (mainly Tartars), and Central and Eastern Europe (mainly Saqaliba).[126]

Under Omani Arabs Zanzibar became East Africa's main slave port, with as many as 50,000 enslaved Africans passing through every year during the 19th century.[127][128] Some historians estimate that between 11 and 18 million African slaves crossed the Red Sea, Indian Ocean, and Sahara Desert from 650 AD to 1900 AD.[3][129][130] Eduard Rüppell described the heavy mortality of the enslaved Sudanese before reaching Egypt: "after the Daftardar bey's 1822 campaign in the southern Nuba mountains, nearly 40,000 slaves were captured. However, through bad treatment, disease and desert travel barely 5000 made it to Egypt."[131]

Central and Eastern European slaves were generally known as Saqaliba (i.e., Slavs).[132] The Moors, starting in the 8th century, also raided coastal areas around the Mediterranean and Atlantic Ocean, and became known as the Barbary pirates.[133] It is estimated that they captured 1.25 million white slaves from Western Europe and North America between the 16th and 19th centuries.[134][135] The mortality rate was very high. For instance, when plague broke out in Algiers' overcrowded slave pens in 1662, some said that it carried off 10,000–20,000 of the city's 30,000 captives.[136]

There are more slaves today than at any point in history,[4] remaining as high as 12 million[5] to 27 million,[6][7][8] even though slavery is now outlawed in all countries.[7][139] Several estimates of the number of slaves in the world have been provided. According to a broad definition of slavery used by Kevin Bales of Free the Slaves (FTS), an advocacy group linked with Anti-Slavery International, there were 27 million people in slavery in 1999, spread all over the world.[140] In 2005, the International Labour Organization provided an estimate of 12.3 million forced labourers in the world.[141] Siddharth Kara has also provided an estimate of 28.4 million slaves at the end of 2006 divided into the following three categories: bonded labour/debt bondage (18.1 million), forced labour (7.6 million), and trafficked slaves (2.7 million).[142] Kara provides a dynamic model to calculate the number of slaves in the world each year, with an estimated 29.2 million at the end of 2009.

The Middle East Quarterly reports that slavery is still endemic in Sudan.
