Mecklenburg was erected in the 12th century. Its ruling house, the Obrodites, were of Slavic origin - unique amongst the German states. The dynasty remained in power for eight centuries. The Duchy was divided into Mecklenburg-Strelitz and Mecklenburg-Schwerin. In the 19th century Mecklenburg got the reputation of being the most backward of the German states; its feudal institutions were abolished only at the downfall of the monarchy in 1918. Currently Mecklenburg forms the western two thirds of the German state of Mecklenburg-Cispomerania.
