some of the outlying German provinces were not serviced by rail until the 1890s, the majority of the population, manufacturing centers, and production centers were linked to the rail network by 1865. Geography, patriotism and language As travel became easier, faster, and less expensive, Germans started to see unity in factors other than their language. The Brothers Grimm, who compiled a massive dictionary known as The Grimm, also assembled a compendium of folk tales and fables, which highlighted the story-telling parallels between different regions. Karl Baedeker wrote guidebooks to different cities and regions of Central Europe, indicating places to stay, sites to visit, and giving a short history of castles, battlefields, famous buildings, and famous people. His guides also included distances, roads to avoid, and hiking paths to follow. The words of August Heinrich Hoffmann von Fallersleben expressed not only the linguistic unity of the German people but also their geographic unity. In Deutschland, Deutschland über Alles, officially called Das Lied der Deutschen ("The Song of the Germans"), Fallersleben called upon sovereigns throughout the German states to recognize the unifying characteristics of the German people. Such other patriotic songs as "Die Wacht am Rhein" ("The Watch on the Rhine") by Max Schneckenburger began to focus attention on geographic space, not limiting "Germanness" to a common language. Schneckenburger wrote "The Watch on the Rhine" in a specific patriotic response to French assertions that the Rhine was France's "natural" eastern boundary. In the refrain, "Dear fatherland, dear fatherland, put your mind to rest / The watch stands true on the Rhine", and in such other patriotic poetry as Nicholaus Becker's "Das Rheinlied" ("The Rhine"), Germans were called upon to defend their territorial homeland. In 1807, Alexander von Humboldt argued that national character reflected geographic influence, linking landscape to people. Concurrent with this idea, movements to preserve old fortresses and historic sites emerged, and these particularly focused on the Rhineland, the site of so many confrontations with France and Spain. German revolutions and Polish uprising of 1848–49 The widespread—mainly German—revolutions of 1848–49 sought unification of Germany under a single constitution. The revolutionaries pressured various state governments, particularly those in the Rhineland, for a parliamentary assembly that would have the responsibility to draft a constitution. Ultimately, many of the left-wing revolutionaries hoped this constitution would establish universal male suffrage, a permanent national parliament, and a unified Germany, possibly under the leadership of the Prussian
