Alexander the Great was a hellenic person as far as a I understand and have been taught.
He was not slavic speaking as he appeared and ruled some 1000 years (roughly speaking) before slavic tribes made it to the balkans. Had he lived today we would have referred to him as a member the modern greek nation.
Hence, to include Alexander the Great in a list of Slavic Warlords is categorically and fundamentally wrong.
Macedonians of today on the other hand are slavs by all means and do have several historic warlords in their slavic ranks that could have been included in this list above. Alexander the Great was not one of them though. He was a hellenic person and belongs to the history of ancient Greece, not modern Macedonia, Former Republic of Yugoslavia.
