Antiterrorismens idéhistorie: Stater og vold i 500 år edited by Mikkel Thrup & Morten Brænder is a Danish-language anthology of academic essays about the history and development of the ideas behind both local and international terrorism and counter-strategies, including various revolutions, political movements, mercenary and guerilla tactics, etc., over the course of the past few centuries, free courtesy of Aarhus University Press.
This is their featured Danish-language Free Book of the Month selection for February (make love, not war?

), and covers a fairly broad range of areas and topics both well-known and obscure, from revolutions like the French Reign of Terror to some shenanigans going on with the British South Africa Company (probably the Boer War; the timing looks right for that), to outside-sponsored insurgencies like the decades-long Afghanistan situation, to fascist Italy and Soviet internal politics, a few really old things that happened in Europe near the end of the Renaissance, and many more.
Currently free throughout the month of February directly @
the university's dedicated promo page (DRM-free PDF available worldwide).
Beskrivelse på dansk
Flyene mod New Yorks tvillingetårne, turistmassakren på Bali, bomber og giftgas mod busser, tog og undergrundstog i London, Madrid og Tokyo - terrorismen er over os. Men er det en fuldstændig ny situation? Denne antologi søger svaret i idéhistorien og giver en grundig indsigt i, hvordan antiterrorisme - statens bekæmpelse af terrorisme - har udfoldet sig de seneste 500 år.
