In 1350 Heinrich der Euchendorfer acquired land belonging to the Abbey of St. Nikola at Leibrecht.

On October 7, 1334 the Holy Roman Emperor Louis IV and his cousin Duke Henry of Lower Bavaria met in Eichendorf for reconciliation talks.

The area was badly affected in the War of the Succession of Landshut; As recompense to the townsfolk for reconstruction, Duke William IV allowed a fourth annual market.

In the Thirty Years' War, Swedish troops burnt Eichendorf to the ground (completely, with the exception of the church).

The opening of the train line from Aufhausen to Kröhstorf in 1915 gave the town its first rail connection.
