Through Border, NATO and Warsaw Pact

The inner German border was formally established by the Potsdam Agreement on 1 August 1945 as the boundary between the Western and Soviet occupation zones in Allied-occupied Germany. On the Eastern side, it was made one of the world's most heavily fortified frontiers, defined by a continuous line of high metal fences and walls, barbed wire, alarms, anti-vehicle ditches, watchtowers, automatic booby traps and minefields. It was patrolled by 50,000 armed Border Troops of the GDR who faced tens of thousands of West German, British and US guards and soldiers. In the hinterlands behind the border, more than a million NATO and Warsaw Pact troops awaited the possible outbreak of World War III in Europe. It was a physical manifestation of Winston Churchill's metaphorical Iron Curtain that separated the Soviet and Western blocs during the Cold War. Built by the East German government in phases from 1952 to the late 1980s, the fortifications were constructed to stop Republikflucht, the large-scale emigration of East German citizens to the West, about 1,000 of whom are said to have died trying to cross it during its 45-year existence. It caused widespread economic and social disruption on both sides; East Germans living nearby suffered especially draconian restrictions.

On 9 November 1989, during Die Wende, the East German government announced the opening of the inner German border and the Berlin Wall. Subsequently, millions of East Germans poured into the West to visit, and hundreds of thousands moved permanently to the West in the following months. More crossings were opened, and ties between long-divided communities were re-established as border controls became little more than a cursory formality. The inner German border was not completely abandoned until 1 July 1990, exactly 45 years to the day since its establishment, and only three months before German reunification formally ended the GDR. Little remains of its fortifications, and its route has been declared part of a European Green Belt linking national parks and nature reserves along the course of the old Iron Curtain from the Arctic Circle to the Black Sea. Museums and memorials along the old border commemorate the division and the reunification of Germany and, in some places, preserve elements of the fortifications.

Development of the inner German border

Origins

The inner German border originated from the Second World War Allies' plans to divide a defeated Germany into occupation zones. The boundaries between these zones were drawn along the territorial boundaries of 19th-century German states and provinces that had largely disappeared with the unification of Germany in 1871. Three zones were agreed on, each covering roughly a third of Germany's territories: a British zone in the north-west, an American zone in the south and a Soviet zone in the east. France was later given a zone in the far west of Germany, carved out of the British and American zones.

The division of Germany was official on 1 August 1945. Because of the unexpectedly rapid Allied advances through central Germany in the final weeks of the war, British and American troops occupied large areas of territory that had been assigned to the Soviet zone of occupation. The redeployment of Western troops prompted many Germans to flee west to escape the Russians' takeover of the remainder of the Soviet zone.

The wartime Allies initially worked together under the auspices of the Allied Control Council (ACC) for Germany. Cooperation between the Western Allies and the Soviets ultimately broke down because of disagreements over Germany's political and economic future. In May 1949, the three western occupation zones were merged to form the Federal Republic of Germany (FRG), a capitalist state with free and fair elections. The Soviet zone became the German Democratic Republic (GDR), a communist state where voters were restricted to electing communist candidates.

From the outset, West Germany and the western Allies rejected East Germany's legitimacy. The creation of East Germany was deemed a communist fait accompli, without a freely or fairly elected government. West Germany regarded German citizenship and rights as applying equally to East and West German citizens. An East German who escaped or was released to the West was automatically granted West German rights, including residence and the right to work; West German laws were deemed to be applicable in the East. East Germans thus had a powerful incentive to move to the West, where they would enjoy greater freedom and economic prospects. The East German government sought to define the country as a legitimate state in its own right and portrayed West Germany as enemy territory (feindliches Ausland) – a capitalist, semi-fascist state that exploited its citizens, sought to regain the lost territories of the Third Reich, and stood opposed to the peaceful socialism of the GDR.

1945–1952: the "Green Border"

In the early days of the occupation, the Allies controlled traffic between the zones to manage the flow of refugees and prevent the escape of former Nazi officials and intelligence officers. These controls were gradually lifted in the Western zones, but were tightened between Western and Soviet zones in 1946 to stem a flow of economic and political refugees from the Soviet zone. Between October 1945 and June 1946, 1.6 million Germans left the Soviet zone for the west.

The east–west interzonal border became steadily more tense as the relationship between the Western Allies and the Soviets deteriorated. From September 1947, an increasingly strict regime was imposed on the eastern Soviet zone boundary. The number of Soviet soldiers on the boundary was increased and supplemented with border guards from the newly established East German Volkspolizei ("People's Police"). Many unofficial crossing points were blocked with ditches and barricades. The West Germans also stepped up security with the establishment in 1952 of the Federal Border Protection force of 20,000 men; – the Bundesgrenzschutz, or BGS – however, Allied troops (the British in the north, the Americans in the south) retained responsibility for the military security of the border.

The boundary line was nonetheless still fairly easy to cross. Local inhabitants were able to maintain fields on the other side, or even to live on one side and work on the other. Refugees were able to sneak across or bribe the guards, and the smuggling of goods in both directions was rife. The flow of emigrants remained large despite the increase in East German security measures: 675,000 people fled to West Germany between 1949 and 1952.

Phases of development of the inner German border

1952–1967: the "Special Regime"

The relative openness of the border ended abruptly on 26 May 1952 when the GDR implemented a "special regime on the demarcation line", ostensibly justified as a measure to keep out "spies, diversionists, terrorists and smugglers". In reality, the East German move was taken to limit the continuing exodus of its citizens, which threatened the viability of the GDR's economy.

A ploughed strip 10 m (32.8 ft) wide was created along the entire length of the inner German border. An adjoining "protective strip" (Schutzstreifen) 500 m (1,640 ft) wide was placed under tight control. A "restricted zone" (Sperrzone) a further 5 km (3.1 mile) wide was created in which only those holding a special permit could live or work. Trees and brush were cut down along the border to clear lines of sight for the guards and to eliminate cover for would-be crossers. Houses adjoining the border were torn down, bridges were closed and barbed-wire fencing was put up in many places. Farmers were permitted to work their fields along the border only in daylight hours and under the watch of armed guards, who were authorised to use weapons if their orders were not obeyed.

Border communities on both sides suffered acute disruption. Farms, coal mines and even houses were split in two by the sudden closure of the border. More than 8,300 East German civilians living along the border were forcibly resettled in a programme codenamed "Operation Vermin" (Aktion Ungeziefer). Another 3,000 residents, realising they were about to be expelled from their homes, fled to the West. The seal around the country was expanded in July 1962 when the GDR declared its entire Baltic coast a border zone subject to closures and restrictions.

The border between East and West Berlin was also significantly tightened, although not fully closed; East Germans were still able to cross into West Berlin, which then became the main route by which East Germans migrated to the West. Between 1949 and the building of the Berlin Wall in 1961, an estimated 3.5 million East Germans – a sixth of the entire population – emigrated to the West, most via Berlin.

1967–1989: the "Modern Frontier"

The GDR decided to upgrade the fortifications in the late 1960s to establish a "modern frontier" that would be far more difficult to cross. Barbed-wire fences were replaced with harder-to-climb expanded metal barriers; directional anti-personnel mines and anti-vehicle ditches blocked the movement of people and vehicles; tripwires and electric signals helped guards to detect escapees; all-weather patrol roads enabled rapid access to any point along the border; and wooden guard towers were replaced with prefabricated concrete towers and observation bunkers.

Construction of the new border system started in September 1967. Nearly 1,300 kilometres (808 mi) of new fencing was built, usually further back from the geographical line than the old barbed-wire fences. The upgrade programme continued well into the 1980s. The new system immediately reduced the number of successful escapes from around 1,000 people a year in the mid-1960s to only about 120 per year a decade later.

The introduction of West German Chancellor Willy Brandt's Ostpolitik ("Eastern Policy") at the end of the 1960s reduced tensions between the two German states. It led to a series of treaties and agreements in the early 1970s, most significantly a treaty in which East and West Germany recognised each other's sovereignty and supported each other's applications for UN membership, although neither state changed its view on the citizenship issue. Reunification remained a theoretical objective for West Germany, but in practice that objective was put aside by the West and abandoned entirely by the East. New crossing points were established and East German crossing regulations were slightly relaxed, although the fortifications were as rigorously maintained as ever.

In 1988, the GDR leadership considered proposals to replace the expensive and intrusive fortifications with a high-technology system codenamed Grenze 2000. Grenze 2000 meant that the whole border control process would be automated and digitised, which means searches would no longer require physical card indexes and passport control would no longer require guards. Visas and access rights would all be completed by a centrally networked PC, namely the EC 1834. Based on technology used by the Soviet Army during the Soviet–Afghan War, it would have replaced the fences with infrared barriers, radio beacons, vibration detectors, radio-frequency reconnaissance equipment and electrical surge protectors. However, the plan was never implemented due to German reunification two years later.
