Comparative analyses of labour in Russia and the West often assume a dividing line between free and forced labour that is universally applicable. The first aim of this article is to show that, in Russia, the historical and institutional definition of serfdom poses a problem. I will therefore explore Russian legislation, and how it was applied, from the sixteenth to the nineteenth century. Contrary to generally accepted arguments, serfdom as such was never clearly introduced institutionally in Russia. I will also discuss the presence of slaves in Russia, and the association between certain forms of servitude (especially for debt) and slavery. The presence of chattel slaves in the empire was related to territorial expansion, and to commercial relations with the Caucasus and the Ottoman Empire. Russian forms of bondage are compared to those in other situations, such as indentured service in the West, debt servitude in India, and Islamic slavery. My conclusion is that, not only in Russia but also around the globe, the prevailing forms of labour were not those familiar to us today, which were not introduced until the early twentieth century. Russia constituted an extreme case in a world in which severe constraints were imposed everywhere on labour and its movement, and the legal status of the wage earner and the peasant was lower than that of the master.
