Even if Poland existed, it would be sandwiched between much more powerful nations, namely Austria, Prussia (Or whatever bigger nation Prussia forms into) and Russia.Poland doesn't exist, so you would have to create it before you could create Poland-Lithuania.Poland-Lithuania doesn't exist, so you would have to create it.Poland itself has potential for a good economy: there is a sizable population for soldiers and craftsmen, as well as a few coal mines. It can be formed by either Poland, Krakow or Lithuania. In Victoria 2, Poland-Lithuania can be formed as a successor of the Commonwealth and will be fairly powerful upon formation. The Union declined in the 18th century and by 1795, it was completely removed from the map of Europe, being partitioned between Prussia, Austria and Russia. This, coupled with Poland and Lithuania's wars against their common foe in the Teutonic Order, led them to formalise their union into the Polish-Lithuanian Commonwealth. The Poland-Lithuanian state was created in 1386 under a personal union when the crown of Lithuania converted to Christianity under Jogaila and married Jadwiga of Poland. Poland-Lithuanian Commonwealth ceased to exist when it was partitioned in 1771 by Prussia, Russia and Austria
