8 Austria - Habsburg Dynasty II 1720 Confident - Edit
kilometers. The furthest distance between two cities of the empire were between Antwerp (Belgium) and Belgrade (Serbia), however, this is via modern roads so this is likely to have been a greater distance during this period: “In the 1780s the Habsburg dynasty’s holdings stretched from today’s cities of Innsbruck in the west to Lviv in the east, from Milan and Florence on the Italian peninsula to Antwerp on the North Sea and Cluj in the Carpathian Mountains, from Prague in Bohemia to Vukovar and down to Belgrade in the south.” [1] From the capital of Vienna the furthest distance was to Bucharest which was 1070km or 42 days by marching. [2] “Large distances impeded strategic mobility between the Habsburg heartland and periphery. Depending on weather and road conditions, an infantry regiment could expect to march for three weeks from the imperial capital to the Ottoman frontier, two weeks to forward positions in Moravia, a month to the Italian frontier, and about as long to outposts in Poland (see figures 2.2– 2.3).” [3]
