Abstract
This article discusses concepts and realities of “borders” in early modern Europe. It outlines the basic shifts in the relevant terminology with particular emphasis on juridical and political discourses. It focuses on the relative importance of zonal and linear notions of borders, as well as on the growing significance of the natural environment in contemporary thought on the topic. The issue of inter-state relations, in particular as regards the Ottoman Empire, is used to illustrate the political relevance of changing concepts of borders.
Introduction
“Good fences make good neighbours”, the saying goes. While we are not concerned with high walls or neighbourhood relationships, the metaphor nonetheless suggests a number of important questions: What were the basic aspects of borders in medieval times? Was there a major shift from the frontiality concept of the pre-modern state to a more linear model of borders? What did the term “border” signify generally? Were these lines dividing one thing from another real or imaginary?
In general, borders are understood as divisions between cultures, languages, and political and confessional systems. However, throughout most of the early modern period โ as well as in antiquity and the Middle Ages โ they were not conceived of as straight lines marking territories and political dominions. The Roman limes, for instance, the classical division of the “Roman civilization” and the “barbarian world”, represented in practice a nebulous contact zone between conquered lands and those which had withstood invasion, rather than a clearly defined line of division.1 The border concept appears to have gained importance with the emergence of the concept of territorial states in the sixteenth and seventeenth centuries when borders became much more visible and began to be considered and discussed in the context of various aspects of state ideology. Topographical features (such as rivers and mountains) and manmade landmarks (fortresses, etc.) began to increasingly serve as borders. Over the medieval and early modern periods, clear geographical borders were established between the realms of Christianity and Islam, as well as between Catholicism and Orthodoxy.
It should be noted that a comprehensive study of concepts of borders in early modern times is yet to be published, though works covering local, regional and micro-historical aspects are numerous. As a result of the widely varying approaches employed, it is impossible to offer a systematic historiographical summary here. Consequently, the following survey will focus on four major features of the development and spread of the linear concept of borders: (1) etymological aspects, (2) the impact of the doctrine of “natural borders”, (3) new juridical concepts and (4) regional divergences in the case of the Ottoman Empire.
Etymological Aspects
Turning to the question of semantics and the historical development of the term “border”, we note that etymologically the terms ะณัะฐะฝะธัะฐ/ granica (Slavic languages),frontier (English), Grenze (German), frontiรจre (French) and frontera (Spanish)2 signify political frontiers between states. The meanings of these words evolved over time with the changing concept of “frontier”. The expressions frontiรจre and Grenze in the modern sense of frontier began to appear only in the late Middle Ages. As late as the fifteenth century, the term frontier began to acquire the meaning “front part of an army”.3 In the same way, the French frontiรจre signified a military border, as distinct from the more civil concept of limites.4 The term only began to be used in the modern sense of “frontier” in the fifteenth century. In the sixteenth century, there was a further semantic shift in the use of the word “frontier” in the European context. The emerging frontiality manifested itself โ among others ways โ in Luther’s use of the word Grenze (from the Slavic granica) instead of the medieval Mark in his Bible translation.5 The etymology of the Slavic word granica is “edge” or “end” of something.6 Indeed, the name Ukraine itself โ meaning simply “march” โ includes the frontiality concept, denoting initially the zone dividing Polish-Lithuania โ and later Muscovy โ from the Tatars.7
Frontality, Linearity, and “Natural Borders”

In early modern times, the frontier concept increasingly incorporated topographical features into the political reality. In the sixteenth and, even more so, the seventeenth centuries, the idea of “natural borders” began to dominate all aspects of the frontier concept. In an abstract sense, it is as though the ideal political space began to be defined in terms of physical geography. Similarly, in cartography the representation of space saw an increasing correlation between physical and political geography. Maps from antiquity and the Middle Ages characteristically lack precise political borders. Until the seventeenth century, indeed, maps contained representations of continents, regions and major cities, but lacked almost all notion of political borders between states.8 While there was a noticeable change in the sixteenth century with regard to the depiction of political borders on maps, such depictions nonetheless remained rare, with political frontiality being represented by rivers, mountains and other topographical features. According to Wolfgang Schmale, with the improvement of measurement techniques in the seventeenth century “das mentale und kulturell-politische Phรคnomen Grenze wird gewissermaรen materialisiert und zum Bestandteil der Geographie”.9 In the early modern period and particularly in the eighteenth century, the concept of “border” lost its vagueness and acquired linear form. Linearity became the basic principle for visualizing and “expressing” frontiers. Zedler, who compiled the first general encyclopaedia of the modern age, described frontiers in 1735 as follows:
รถffentliche Zeichen und sichtbare Gemercke, dadurch die Landschafften und liegende Gรผter erkenntlich und ordentlich von einander unterschiedlich werden. Sie werden auch Marcken und Untermarcken genennet, darum, daร sie Gemerck und Andeutung geben, wie weit sich ein Land oder Gut erstrecke … Darnach vor das andere werden auch offter Mahlen die Gรผter, und vornemlich die Herrschafften und Gebiete nicht durch aufgerichtete, und mit der Hand-Arbeit gemachte Marck-Steine, sondern von der Natur an die Hand gegebene Grenzen und Marcken von einander unterschieden, das sind selbstgewachsene Marcken, als die Gebรผrge und hohe Spitzen, oder Rรผcken derer Berge. Bisweilen sind auch zu Grenzen gesetzt die Thรคler, die Landstrassen und Fuรsteige, die flรผssenden Wasser und Bรคchlein10
Following Zedler’s example, encyclopaedias in the nineteenth century predominantly defined “border” as an imaginary line defining the outer part of something and where it ends. Moreover, it is the point where the ends of several objects meet, thus creating a line connecting the border points.11 Indeed Zedler’s definition was informed by the idea of “natural borders” โ though not the ideology โ mentioning topographical features, as well as a series of manmade markers such as stones, barriers, pillars, fences, walls, etc., which apparently had a visual purpose.12 This differs significantly from the political theory of limites naturelles, which was prevalent in France from the seventeenth century. The early modern period saw the emergence of state ideologies which endowed state territory and the central absolutist authority with a cult status. In the eyes of politicians of the time, the border was elevated to a key factor, forming an “area of ideology”, in particular with respect to natural borders. The definition of the French historical area in the hexagon between the Pyrenees and the Rhine underlined the homogeneity of that space as a natural territory and corresponded with the perception of ethnic unity.13 Similar processes can be observed in Swedish foreign policy in the sixteenth and seventeenth centuries, when the Baltic Sea became an element of state ideology. In a similar manner, the desire to determine the outer borders of the Holy Roman Empire of the German Nation also led to an elevation of topographical features: The great European rivers Rhine and Danube circumscribed the space containing the German identity.14
Juridicial Concepts

The European renaissance of the Roman judicial tradition in the sixteenth century gave rise to a new theoretical discussion about frontiers and how they are defined. The concept of frontier was transformed into an issue of governmental importance and featured prominently in a number of legal documents.15 From the sixteenth to the eighteenth centuries, the idea of “natural borders” took roots in juridical discourses, as reflected in juridical texts. In the evolving field of international law, for instance, the term fines naturales, which was associated with concrete natural features like rivers, mountain ranges, swamps and deserts, was increasingly employed to denote a particular type of political borders in contrast to more artificial lines of division (termini, limes). This use of terms was largely established by the writings of Hugo Grotius (1583โ1645) and Samuel Pufendorf (1632โ1694).16
Yet Johann Oetinger’s (1577โ1633) Tractatus de jure et controversiis limitum, dating from the first half of the seventeenth century, had already brought the frontier concept noticeably closer to modern concepts of the term.17 Oetinger’s theory employed the notion of sovereignty, using models from natural law. He attempted a justification of existing borders with reference to the “four monarchies” doctrine.18 The will of the Lord divides the land between the nations by means of natural borders:
Den Erdboden hat der gรผtige Gott den Menschen zu bessitzen / a vnd also weiรlich auรgetheilt / daร die Vรถlcker nach ihrer Art vnterschiedliche Wohnungen darinnen haben kรถnnen. Darumb ist derselbe nicht gleichfรถrmig in einerley Gestallt / sondern mit allerley mannigfaltigen Gelegenheiten geschaffen / vnd in absonderliche Gelรคnd von Natur vnterscheiden / welche wir Landschafften heissen. b Dann wir sehen daร ein Land etwan mit Gebรผrgen / ein anders mit Waldungen eingeschlossen: Dieses mit fliessenden Wassern / jenes mit Thรคlern vmbgeben. Etliche Lรคnder liegen in schรถnen ebnen Feld; Etliche gar mitten im Meer / vnd sind also gleichsam durch Natรผrliche Grรคnzen von einander selbsten abgesรถndert. Nun ist zwar Anfangs die Erde zu einem gemeinen Vatterland vnd Geburtstatt allen Menschen geordnet:19
In the late eighteenth century, juridical thought made a clear distinction between natural and manmade frontiers. Karl Gottlob Gรผnther (1752โ1832), for example, wrote the following in his work on European international law:
Die Grenzen des Landes sind entweder solche, wo die Natur selbst die Unterscheidungszeichen an die Hand giebt, welche die Nazionen zur Richtschnur annehmen, und heissen natรผrliche (limites naturales, occupatorii) oder solche, welche durch Kunst und menschlichen Fleis aufgerichtet werden, kรผnstliche (artificiales). Eine dritte Gattung, welche durch Bestimmung abgemessener Rechte in Vertrรคgen festgesetzt werden, heissen politische Grenzen (politici, mensurati). Dieienigen Territorien, welche natรผrliche Grenzen haben, werden von Grotius territoria arcifinia, die beiden andern hingegen limitata genannt.20
In reality, natural barriers such as rivers and mountains need not necessarily be insuperable obstacles and border contours are not a natural phenomenon. Borders are rather a manifestation of competing territorial claims backed up by military force, though based to some extent on geographical reality. For instance, rivers dividing spheres of domination were often defined as borders in peace treaties and international agreements. In the early modern period, border discourses โ political and juridical, as well as historical โ were heavily influenced by the growing number of pan-European military conflicts, such as the Thirty Years’ War of the seventeenth century and the Spanish and Austrian Wars of Succession in the eighteenth century. Not surprisingly, decisions about the future of territories, their eventual division among states, the shaping of new borders, and so on, were issues of primary importance at peace congresses. In this respect, the influence of the newly created media (newspapers, magazines, Flugblรคtter) should not be underestimated, as they gave a platform to publicists from which they affected the visualization of borders and frontiality in the public consciousness.
Regional Divergences: The Ottoman Empire

As regards the transformation from “nebulous” to “linear” concepts of borders, we should bear in mind that while this process is quite obvious in central, western and northern Europe, in the European southeast dominated by the Ottoman Empire more vague distinctions prevailed until the end of the seventeenth century. Even when signing the Peace Treaty of Carlowitz21 with the Habsburg Empire in 1699, the Ottomans were hesitant to agree to the establishment of a border commission to draw the new frontiers where no dividing natural features existed โ specifically, in the land of the Banat of Temesvar, which remained under the Sultan’s rule.22 This peculiar paradox arose out of a particular aspect of European-Ottoman relations from the fifteenth to the seventeenth centuries: the Islamic concept of war and peace.23
The state of the Ottoman Turks became a great power soon after its inception through the ideology of military expansion. The border concept was practically absent. Instead, in the thirteenth and fourteenth centuries the so-called “udj-culture”24 gained prevalence in Asia Minor, aimed not at the preservation of existing frontiers but rather at a continual border expansion through force.25 This tradition remained strong during the course of Ottoman expansion in southeast Europe. To varying degrees over time, the border constituted a continuously changing entity, driven by the armed forces and almost independent of the central authorities.26 A prominent feature of “udj-culture” was thus an offensive, rather than defensive, stance in relation to existing borders. It was underpinned by the militant ideology of Islam: the gaza, or permanent war for the true faith. In the mid-fifteenth century Sultan Mehmed the Conqueror (1432โ1481) tried to limit the authority of the “udj-begs” by placing the whole army under central command. As a result, through the sixteenth century the Ottoman border serhad gradually evolved, though the essence of the frontier concept changed only slightly.27
Despite the fact that border zones (rivers, mountains, seas, etc.) belonged neither to the world of war nor to the world of Islam according to Hanefite Law, it is apparent that the Danube in this very period was still regarded as a part of the dar ul harb.28 This is explained by the fact that, from the end of the fourteenth century to the mid-sixteenth century, the Ottomans were devoted to continuous expansion, which was irreconcilable with the defining of a frontier. In practice, it represented an area of perpetual collision between Christians and Muslims, essentially bearing out the Islamic concept of the world of war. The doctrine of Holy War against the foes of the faith stated that “eternal peace” could not be established with Christian states, meaning that the peace agreements which ended wars were always seen as temporary and the border had the effective status of a demarcation line (Waffenstillstandsgrenze). It was not until the end of the seventeenth century when the Ottomans suffered their first military disaster that they began to develop the same understanding of the frontier which already prevailed in European international relations.
Conclusion
The great geographical discoveries and the emergence of modern cartography in the early modern period, as well as the establishment of the idea of the territorial state, radically changed concepts of frontiers and spatial divisions. The diffuseness which had dominated throughout antiquity and the Middle Ages was gradually replaced by a concept of border as line, both linear and fixed. The cartographic revolution made it possible to establish clear borders employing both topographical features and manmade landmarks. It also enabled the precise plotting of frontiers on maps in relation to political dominions and physical geography. In this way the old diffuse and, to a large extent, abstract divisions were transformed into visible and visualized entities. It is thus possible to speak of a border topos in the social consciousness from the sixteenth to eighteenth centuries.
