Due to the lack of documentary evidence, the year in which Moravia ceased to exist cannot be determined with certainty. Róna-Tas writes that the Hungarians occupied Moravia in 902, Victor Spinei says that this happened in 903 or 904, while according to Spiesz, the Moravian state ceased to exist in 907. The "Raffelstetten Customs Regulations", which was issued in the years 903–906, still refers to the "markets of the Moravians", suggesting that Moravia still existed at that time. It is without doubt that no Moravian forces fought in the battle at "Brezalauspurc", where the Hungarians routed a large Bavarian force in 907.
