Wasn't the word slavic derived from the word slave which the vikings gave as a name to describe the people of the east?  I don't know for sure if that's true, but I have always found the word slavic as a rather unappealing name because it sure sounds like it was derived from the word slave.  I was wondering how Russians feel about the term slavic? I don't know which one was first, but I think that 'slava' ( слава ) in Russian means glorious.
