By the 13th century, a branch of the ancient noble family of Isenburg / Ysenburg, had possessed the Imperial immediate Lordship of Büdingen [4: tome III; p.360] [10: Neue Folge; Band XVII (1998); t.59-76] [9: 1941; p.229-236].

In 1442, the Roman King granted Dietrich / Diether I of Isenburg (+1461) the title of Count of Büdingen [8: Band 5; p.252] [20: Band II; p.212] [10: Neue Folge; Band XVII (1998); t.60] [9: 1941; p.230].
