Why are contrys  named differently ???

Many, many different reasons. Perhaps the word used in one language reflects a name for a region or people that no longer exists, often because many different regions morphed into one, so the name of a country in another language may reflect an older term used even if is no longer accurate. Some place names simply come from the people who inhabit the land. ... Germany's central position in western Europe means that it has historically shared borders with many different groups, and many languages use thename of the first Germanic tribe its speakers came in contact with as aname for the whole region.Germany comes from germania or germanicus. Those terms have a Latin root. In fact, it's believed that the Roman Emperor Julius Caesar may have actually coined the term that led to the modern English word Germanytoday. Caesar used those words to name the tribes that lived in the areaEnglish now calls Germany.
