LTIdėja išleisti šią knygą gimė Valstybės sienos apsaugos tarnybai (VSAT) rengiantis paminėti savo 90-metį, mat 1920 m. vasarį Lietuvos kariuomenė pradėjo saugoti nepriklausomos Lietuvos valstybės sieną. Toks Lietuvos sienos apsaugos jubiliejus minėtas 2010 m. Iki šiol panašaus išsamaus leidinio nebūta, nors atskirų sienos apsaugos istorijos tyrinėjimų ir buvo paskelbta. Tarpukario Lietuvoje buvo išleistas tik vienas leidinys apie Lietuvos policiją, kuriame rašyta ir apie Lietuvos sienos apsaugą, tačiau buvo aptariamas labai trumpas 1924-1928 m. periodas. 1974 m. Čikagoje buvo išleista prisiminimų knyga apie tarpukario Lietuvos policiją, kurioje pateikta įdomios medžiagos apie Pasienio policiją. Tačiau prisiminimai nebuvo paremti archyviniais šaltiniais, todėl tekste nemažai netikslumų. Atkūrus Lietuvos nepriklausomybę, skaitytojus pasiekė net keli leidiniai apie mūsų valstybės sienos apsaugą. Juose aptarti atskiri laikotarpiai. Šiame leidinyje siekta nuosekliai aptarti valstybės sienos apsaugos raidą nuo Lietuvos Didžiosios Kunigaikštystės (LDK) laikų iki šių dienų. [Iš teksto, p. 7].
ENAccording to archival documents, the state of Lithuania, just like other European countries, has done its best to protect and defend the boundaries of its residential areas. The start of Lithuanian state border protection is related to the establishment of a centralised state when Duke Mindaugas, one of the rulers of Lithuanian lands, decisively merged most duchies into a single state in the XIII century. There was dual state border protection in Lithuania at that time. On one hand, state borders were guarded by small groups of guards deployed in small wooden castles of dukes of those lands built near state boundaries. There were soldiers on watch at river fords and on the outskirts of large woodlands bordering neighbours. On noticing any danger, they would immediately jump on their horses and go to the nearest castle to tell about the danger and enemy forces. There was a warning system in place in Lithuania at that time. A large fire would be made on a pre-selected higher hill. All surrounding areas and nearest castles would be warned about a danger by its fumes in the daytime and flames at night. On noticing such a signal, men from the surrounding areas capable of handling a gun would rush to join castle garrisons. On the other hand, starting from the Mindaugas era which saw the establishment of commercial relations with the Livonian Order and subsequently with other neighbours, first customs posts were established at river fords and important roads in order to augment the state budget. The customs charged duties on imported and exported goods. There were armed customs officers at the customs posts, who would not only guard the customs posts but would also immediately inform surrounding castles of an imminent threat. [...].
