This "Russian Prussia" is called Kaliningrad Oblast. The other parts of (Old Baltic) Prussia are now part of Poland and Lithuania. Prussia has two meanings: The (German) Kingdom of Prussia on one hand and Old/Baltic Prussia on the other hand. The Kingdom of Prussia got its name from the original Baltic Prussia (in Old Prussian language it is called "Prūsa"). The original Baltic Prussia was the easternmost province of the Kingdom of Prussia. That Province of Prussia inside the Kingdom of Prussia was most of the time parted into East Prussia and West Prussia.
