Interstate border protection in East-Central Europe in the 18th–19th centuries

Abstract

Abstract. The study examines the highly complex system of interstate border protection in East-Central Europe during the 18th and 19th centuries, highlighting its political, military, economic, and social significance at the convergence point of the region’s great powers: the Habsburg Monarchy, the Russian Empire, Prussia, and the Ottoman Empire. At the turn of the 18th and 19th centuries, the Habsburg Monarchy possessed one of the most extensive border systems on the continent. Along the hundreds of kilometers of southern and eastern borders, the Military Frontier (Militärgrenze) was established in the 18th century. This institution simultaneously served military defense, the extension of state administration, and public health and police control. The organizational structure of the Military Frontier provided the institutional and personnel conditions that enabled the empire to effectively defend against epidemics (Rothenberg 1966, p. 45). The organizational structure and personnel numbers of the Military Frontier ensured the quick mobilization of the army for the empire, which was critical for the Habsburgs' 18th-century war efforts, particularly against the Turks. (Hochedlinger, 2003). The Partitions of Poland created new borders and enforced strict control. Border surveillance also acquired an economic function at this time (customs, defense against smuggling). The Napoleonic Wars increased its strategic importance in the 19th century. During the era of the Holy Alliance, the function expanded to include police-political tasks (controlling revolutionary ideas). The Military Frontier became a key player during the events of 1848–49. The latter half of the century saw the formation of nation-states, bringing new border arrangements. The practice of the "cordon sanitaire" was proven effective during plague defense as early as the 18th century. This involved securing the border line with military and civil guards to control the movement of goods and persons. This experience formed the basis for establishing a new type of public health border control during the cholera epidemics of the early 19th century. In 1831, the Habsburg Monarchy established a triple military cordon in the region of Galicia, Bukovina, and Bessarabia, imposing a strict blockade along the Russian border. The cordon aimed to completely isolate infected areas and place so-called "second-class" individuals suspected of having the plague or cholera into quarantine before they entered the country. The border closure was therefore not merely a medical measure, but also a tool for maintaining imperial order and security. During the cholera threat, the Habsburg government feared the spread of revolutionary ideas and national uprisings in addition to the epidemic ; thus, border control served both the protection of state order and ideological security.
