Slavery was a part of Ottoman society, with most slaves employed as domestic servants. Agricultural slavery, such as that which was widespread in the Americas, was relatively rare. Unlike systems of chattel slavery, slaves under Islamic law were not regarded as movable property, but maintained basic, though limited, rights. This gave them a degree of protection against abuse. Female slaves were still sold in the Empire as late as 1908. During the 19th century the Empire came under pressure from Western European countries to outlaw the practice. Policies developed by various Sultans throughout the 19th century attempted to curtail the Ottoman slave trade but slavery had centuries of religious backing and sanction and so slavery was never abolished in the Empire.
