Map of present day Poland including the former German occupied towns from which local overprints were issued at the end of World War I
Poland was partitioned between Germany, Austria and the Soviet Union. German occupied Poland was called Generalgouvernement Warschau (General Government Warsaw). In 1915, Germany conquered the Soviet portion which was called Russisch-Polen (Russian Poland). In German occupied Poland, Germania stamps were overprinted for Russisch-Polen (Fischer ON 1-5, Michel 1-5) and for Generalgouvernement Warschau (Michel / Fischer ON 6-10 and 12-16). These stamps were used by the Poles to produce local stamps. The original Germania stamps which were overprinted Russisch-Polen are Michel 84, 85, 86, 87 and 90, respectively and for Generalgouvernement Warschau Michel 98, 84, 85, 99, 86, 100, 101, 87, 89, 90 and 92, respectively. Local overprints on former German occupied territory were generally made with a handstamp using black, blue, violet or red ink. Most overprints are Poczta Polska, with or without a Polish eagle and sometimes bars cancelling the German text.
