Valuable labour for the social security system and the social policy of the Bulgarian government

Abstract
The new monograph of Assoc. Nikola Konstantinov* - one of the leading Bulgarian authors on the history of social insurance in our country, covers a relatively large period. Its chronological frames are well grounded - the beginning was set in 1880, when the Parliament adopted the first normative act on this matter - on the pensions of the volunteers who took part in the Russo-Turkish War of Liberation of 1877-1878. 1925 was taken as the final limit - then the formation of the insurance system in Bulgaria was completed with the Law on Work Placement and Unemployment Insurance.
