The territory in question was once apart of the german province of east prussia. However during the second world war it was overrun by soviet forces.
After the second world war the map of eastern europe was redrawn poland was moved westward towards the Oder river the arguement was that would be a
better natural barrier in case of future german aggression. So the german provinces of posen, silesia and west prussia as well as part of east prussia
were given to poland while poland gave its eastern provinces to russia. Russia took the Baltic nations of estonia, latvia and lithuania and the rest
of east prussia that surrounded the city of Konigsburg now Kaliningrad. The area was largely abandoned by its german population and was resettled by
russians. So after the collapse of the soviet union it became apart of the russian federation. Hope that answers your question if not then run a
google search on Kaliningrad and wikipedia is always a good bet.
