The 5th Division ("5.
 Division") was a unit of the Prussian/German Army.
 It was formed in Crossen in 1816 as a brigade, moved to Frankfurt an der Oder in 1817, and became the 5th Division on September 5, 1818.
 The headquarters moved to Berlin in 1840 and back to Frankfurt in 1845.
 The division was subordinated in peacetime to the III Army Corps ("III.
 Armeekorps").
 The division was disbanded in 1919 during the demobilization of the German Army after World War I.
 The division was recruited in the Province of Brandenburg.
The Battle of Kassel was a four-day struggle between the U.S. Army and the German Army in April 1945 for Kassel, a medium-sized city 140 kilometers northeast of Frankfurt am Main, which also is the second-largest city in Hesse (after Frankfurt).
 The battle resulted as the U.S. Third Army pushed northeast from the region of Frankfurt and Mainz.
 The battle opened on April 1, 1945 and ended with an American victory three days later.
 Opposing the Third Army's 80th Infantry Division were an infantry replacement battalion, some heavy tanks, and anti-aircraft guns. Although the Germans gave battle at Kassel, their army was on the brink of collapse as the Western Allies and the Red Army made deep inroads into Germany.
 The defense of Kassel did not materially impede the Allied advance, and, one month after the battle ended, Germany was forced to capitulate.
The Frankfurt–Mannheim high-speed railway (the official name is Rhine/Main-Rhine/Neckar high-speed line) is a proposed high-speed railway line from Frankfurt am Main to the Mannheim–Stuttgart high-speed railway near Mannheim.
 Supporting speeds up to 300 km/h, it will run parallel to the A 5, A 6, and A 67.
 The new high-speed line will relieve the old double-track Mannheim–Frankfurt railway, which is currently operating at full capacity.
The Battle of Frankfurt an der Oder on 13/15 April 1631 was a battle of the Thirty Years' War, fought between the Swedish Empire and the Holy Roman Empire for the strategically important, fortified Oder crossing Frankfurt an der Oder, Brandenburg, Germany.
 The town was the first major Imperial stronghold attacked by Sweden outside the Duchy of Pomerania, where Sweden had established a bridgehead in 1630.
 After a two-day siege, Swedish forces, supported by Scottish auxiliaries, stormed the town.
 The result was a Swedish victory.
 With the subsequent clearance of nearby Landsberg (Warthe) (now Gorzow), Frankfurt served to protect the Swedish army's rear when Gustavus Adolphus of Sweden proceeded further into Central Germany.
The positivism dispute (German: "Positivismusstreit") was a political-philosophical dispute between the critical rationalists (Karl Popper, Hans Albert) and the Frankfurt School (Theodor Adorno, Jürgen Habermas) in 1961, about the methodology of the social sciences.
 It grew into a broad discussion within German sociology from 1961 to 1969.
 The naming itself is controversial, since it was the Frankfurt School proponents who accused the critical rationalists of being positivists—while the latter considered themselves as opponents of positivism.
 On the political level, it was a dispute between the leftist Frankfurt School proponents supporting revolution, and the allegedly bourgeois critical rationalists supporting reform as the method to be preferred to change society.
Musikmesse Frankfurt is an international fair regarding the music industry, and takes place in Frankfurt am Main, Germany.
