Saksaa (Finnish) - obviously from Saxony (in German "Sachsen") Elector August I of Saxony (also called August the Strong) was choosen as King August II of Poland and Grand Duke of Lithuania in 1697. As I believe that Finland and Estonia belonged in that time to Lithuania, the name of Germany in the Finish language comes from this event.

What do you mean? Deutschland (German)? "deutsch" from Old High German "diutisc" or "thiod" (tribe, people). From the 10th century on in use for East Francia (roughly today's Germany). Germany (English)? From germanic (Don't confuse "German" with "Germanic".) tribes. They were more often called by their individual (romanized) names. The term is attributed to Poseidonios of Rhodos (80 BC). Allemagne (French)? The "Alamanni" have been a group of germanic tribes, located in southwest Germany, the area next to today's France (and even in today's eastern France and northern Switzerland). deguo (Chinese)? (That's your task. Where does it come from?)

well, germans dont call themself germans. this term derived from latin. the romans used this term for all the different german tribes. We use the word Deutsch, which derived from an older german language and means "dem volk zugehörig" which means belonging to the people.
