Deggingen and the town of Reichenbach im Täle were annexed by the Kingdom of Württemberg when, in 1806, the Lordship of Wiesensteig was mediatized to them.

The two towns expanded dramatically after World War II, though Reichenbach im Täle's growth tapered off by the end of the 1960s.

[3] The municipality (Gemeinde) of Deggingen is found in the district of Göppingen, in Baden-Württemberg, one of the 16 States of the Federal Republic of Germany.

[3] The municipal coat of arms of Deggingen displays the head of an elephant, in white, above a yellow, six-pointed star, upon a field of red.

The elephant is taken from the coat of arms of the County of Helfenstein, as was the red-yellow tincture, while the six-pointed star has been a symbol of Deggingen since 1551.
