The GDR, or The Very Shortest History of East Elbia
East Germany didn't become different because of the Russian occupation of 1945-1989; the Russians occupied the place because it had always been different.
Otto the Great invaded across the Elbe in 935 AD; the Slavs threw the Germans back out in 982 AD; the Germans tried again in 1127 and over the next two centuries they largely (but never completely) succeeded in supplanting the Slavs up to the river Oder. The Teutonic Knights went further until the Poles smashed them in 1410. Prussia was born under Polish suzerainty as an act of revolt again Rome in 1525, rose to fame in battle against Sweden, was made a great power by victories between the Elbe and the Oder, then saved from abolition by the Tsar in 1807. The fatal inability of the western Germans to unite allowed Prussia to conquer them after a single great battle on the Elbe in 1866. Prussia smashed France in 1870; it thereafter dragooned the Germans into providing manpower and money for its bid(s) to settle the 1,000-year struggle with the Slavs. That struggle ended in 1945 with part of East Elbia lost forever and what was left, between Elbe and Oder, a helpless colony of Russia.
With the creation of the GDR, this rump East Elbia formally became what it had always really been: the odd German-speaking man out in a Slavic Eastern Europe. Until the wall went up in 1961, the East Germans - above all, the young and educated - undertook a new Ostflucht to West Germany at an average rate of about 200,000 year on year, about the same rate as in the Ostflucht from the 1850s onwards. If Russia's clients hadn't built and maintained a deadly barrier to stop the fugitives in the meantime, by 1989 there would have been hardly any Germans left beyond the Elbe.
