The Russian poll was so popular I figured I'd continue in the West and if we're continuing to Europe we have to go to German first. Try to keep it to 3 votes but I understand if you did on or two more. 
Next door in Vienna, of course, along with Mozart, Haydn, Mahler, and Schubert.(as did Schoenberg... hey, where's Schoenberg in this poll!?).
By that logic, Britten is an American composer or Copland is an English composer. For that matter, that would make Bob Marley an English composer. I'm sure he would have agreed with that ???Well... Personally I follow the same standard that is largely employed when speaking of literature. "German Literature" is than written in German... regardless of whether the author was born in what is now Germany, Poland, Austria, or the Czech Republic. If a composer's primary language was German... then I think of him as German... or as I sometimes refer to it (tongue in cheek): the Austro-Germanic Hegemony.
So you included Bach, Beethoven, and Brahms? Sounds more like an agendaWagner did occur to me but I just did a whole thread about him and I thought the inclusion of some lesser under appreciated composers would be nice for a change.
Don't quite agree with this. When it comes to Classical Music, there have always been stylistic differences between different countries and cultures and they seemed to become greater as time went on. I think if you spend enough time listening to different composers you can start to hear the "German" "French or whatever accents in the music (unless of course a Russian composer is deliberately writing in a German style, for example).I'm interested in the possibility that 'nationality' is of no significance at all in consideration of a composer's greatness. Who cares what the geo-political situation was at the time of Beethoven or Wagner...they wrote music in no language - that's why we can all listen to it and enjoy it without anyone having to translate.
