The rayah or reaya was a member of the tax-paying lower class of Ottoman society, in contrast to the askeri (military) and kul (slaves, including Janissaries). Ottoman subjects were initially divided into roughly two taxable classes, the military class (askeri) and working class (rayah). The term was attributed to the peasant tax-paying subjects of the Timariots, active until the disintegration of the timar system in the 16th century. A clear social distinction was made between the Muslim and Christian rayah, with legal and religious discrimination against the latter, viewed of as infidels (giaour). Although the term initially and generally was used to encompass all of the subject lower class (taxed Muslims, Christians and Jews), it was particularly attributed to the Christian (also called zimmi), mostly Eastern Orthodox communities (the Rum Millet) in the Balkans (Rumelia).
