King of Lotharingia
835 CE to 900 CE
Berengar I is a 9th-century nobleman of East Francia, a son of Gebhard, Count of Lahngau, and younger brother of Udo.
He and his brother are created Margraves of Neustria by Charles the Bald in 861.
He is possibly a Conradine, a relative for sure of Adalard the Seneschal, a Girardid.
Berengar is probably the namesake of Berengar II of Neustria, who is probably the son of Berengar I's successor, Henry of Franconia.
