Slavs appeared in the 6th century AD.
it is not true. Nation, which already in 6th century lived in vast areas from Bavaria to Ural could not appear overnight (Prokopios wrote that Slvs occupy enormous spaces in Europe, he was Greek, so you should believe him). There were several Slav nations already described in ancient times - Anti, Wans, Scythians, Venedi (also called Vinidi, in German lands they were called Windisch), Slavi, Slavoni, Slovens, etc. For example in times of Vannius kingdom (Van - sic!) the realia in todays Slovakia and Hungary, as well as Austria up to Salzburgh had Slav and Celtic names. Realia means mountains, hills, rivers, parts of land, forests, etc. In spite of that people talk mof Vannius kingdom and Kvads as of German, just because Romans wrote so. But Romans did not differentiate too much between Slavs and Germans, neither Cletic - e.g. the name Germain was name of a Celtic(!!!) tribe in Galia, not of Allamanic or Teutonic. Etc. Proofs are many in archives, especially German and Italian, but in French, too, and mainly in Vatican. It has been the "historiography" in 19th century, when the history of Slavs had been crooked and twisted. Did you ever hear of Veles book? Btw in German and Sweedish sagas you an find, that when their ancestors came to their homeland from East, the land had been populated already by Wans, Jomsvikings were of Slav origin probably, too. etc, etc, etc...
Jeez.. don't you know? By western European standards we as Slavonics.. emerged from the ground somewhere in Ukraine during the 6th century and then without a fight took over half of Europe and kept it till today. Learn your mainstream history!!
