Ossi may refer to:
The new federal states of Germany (German: die neuen Bundesländer) are the five re-established states in the former German Democratic Republic that acceded to the Federal Republic of Germany with its 10 states upon German reunification on 3 October 1990. Subsequently, the Gesellschaft für deutsche Sprache chose the term as German Word of the Year.
The new states, which had been abolished by the East German government in 1952 and were re-established in 1990, are Brandenburg, Mecklenburg-Vorpommern, Saxony, Saxony-Anhalt and Thuringia. The state of Berlin, the result of a merger between East and West Berlin, is usually not considered one of the new states, although many of its residents are former East Germans.
Since the reunification, Germany thus consists of 16 states with equal legal statuses. Yet the process of the "inner reunification" between the former Eastern and Western Germany is still ongoing.
Persisting differences in culture and mentality among the old East Germany and old West Germany are often referred to as the "wall in the head" ("Mauer im Kopf"). "Ossis" ("Easties") are stereotyped as racist, poor and largely influenced by Russian culture. "Wessis" ("Westies") are usually considered snobbish, dishonest, wealthy, and selfish. The terms can be considered disparaging.
