Tuhia he tomokanga mo tenei waahanga - Ko te Great Moravia i whakahaere poto i te rangatira Bohemian i te matenga o Bořivoj i te 888/890 tae noa ki te 895, ko tana tama a Spytihněv me te rangatira Slavník a Witizla i oati ki te kingi o East Frankish a Arnulf o Carinthia i Regensburg. Ko ia me tana teina ko Vratislaus i whakahaere i Central Bohemia huri noa i Prague. I taea e ratou te tiaki i to ratou kingitanga mai i nga ope o Magyar i patu i te ope o East Frankish i te 907 Pakanga o Pressburg
i te wā o te wikitōria o Hungarian o te Carpathian Basin. I wehe atu i Byzantium na te aroaro o Hungarian, i noho te rangatiratanga o Bohemia hei kawanatanga motuhake ahakoa kei te atarangi tonu o East Francia; i utua e nga rangatira rangatira ki nga rangatira o Bavarian hei utu mo te whakaū i te tiriti rangimarie. Ko te tama a Vratislaus a Wenceslaus, i whakahaere mai i te 921, i whakaaetia hei upoko o te uniana iwi Bohemian; heoi, me aro ia ki te riri o tona hoa tata a Duke Arnulf o Bavaria me tana hoa kaha, te kingi Saxon a Henry I o Tiamana. I pupuri a Wenceslaus i tana mana rangatira ma te tuku ki a Kingi Henry i te 929, i muri i tana kohuru e tana tuakana a Boleslaus.
