Although the source cited above and other sources mention that Great Moravia disappeared without trace and that its inhabitants left for the Bulgars, with Croats and Magyars following their victories, archaeological research and toponyms suggest the continuity of Slavic population in the valleys of the rivers of the Inner Western Carpathians. Moreover, there are sporadic references to Great Moravia from later years: in 924/925, both Folkuin in his "Gesta abb. Lobiensium" and Ruotger in "Archiepiscopi Coloniensis Vita Brunonis" mention Great Moravia. In 942, Magyar warriors captured during their raid in al-Andalus said that Moravia is the northern neighbour of their people. The fate of the northern and western parts of former Central Europe in the 10th century is thus largely unclear.
