It was split between the victors, and lost its world leadership roles.
With the reunification of Germany in 1990, Berlin was restored as a capital and as a major world city. It may have roots in the language of West Slavic inhabitants of the area of today's Berlin, and may be related to the Old Polabian stem berl-/birl- ("swamp"). The oldest human traces, mainly arrowheads, in the area of later Berlin are dating to the 9th millennium BC.
The history of Berlin starts with its foundation in the 13th century.
It became the capital of the Margraviate of Brandenburg in 1417, and later of Brandenburg-Prussia, and the Kingdom of Prussia.
In the 6th century Slavic tribes, the later known Hevelli and Sprevane, reached the region.
Afterwards the two settlements merged into the town of Berlin-Cölln; they formally merged in 1432.
Albert the Bear also bequeathed to Berlin the emblem of the bear, which has appeared on its coat of arms ever since.
In 1415, Frederick I became the elector of the Margraviate of Brandenburg, which he ruled until 1440.
Subsequent members of the Hohenzollern family ruled until 1918 in Berlin, first as electors of Brandenburg, then as kings of Prussia, and finally as German emperors.
Today their traces can mainly be found at plateaus or next to waters.
