Whakaotihia te rerenga e whai ake nei: I riro mai i a Great Moravia te mana whakahaere mo te rangatira Bohemian i te matenga o Bořivoj i te 888/890 tae noa ki te 895, i oati tana tama a Spytihněv me te rangatira Slavník a Witizla 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 rātau te tiaki i tō rātau rangatiratanga mai i ngā ope o Magyars i patu i tētahi ope o Rāwhiti Frankish i te tau 907
Ko te Pakanga o Pressburg i te wa o te wikitoria o Hungary 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.
