Where did the German weird "Deutsche"/"Deutschland" come from?

by chrismamo1

Germany is notorious for it's factured past, which is evident in the many different names that other nations have for them (Allemande, Niemcy, etc.). Perhaps I'm missing something about the German language, but afaik Germany is pretty much always called Deutschland. How was this chosen?
