Бакинская губерния
"Note": There is an actual city of Shemakha (also spelled "Şamaxı", "Schemacha" and "Shamakhy"), which is the capital of the Shamakhi Rayon of Azerbaijan. In Pushkin's day it was an important city and capital of what was to become the Baku Governorate. But the realm of that name, ruled by its tsaritsa, bears little resemblance to today's Shemakha and region; Pushkin likely seized the name for convenience, to conjure an exotic monarchy.
