In the 18th century, there was again peace and modest growth in Ilsfeld.
After the Napoleonic Wars, following which the entire surrounding area became Württemberg territory, and after a territorial reorganization of the Duchy, Ilsfeld belonged to the Oberamt of Bietigheim beginning in 1808, and then to the Oberamt of Besigheim beginning in 1810.
The settlement slowly grew beyond its medieval borders, first west and east along the main street.
By 1832, the town gates no longer existed.
In 1844, for the first time, the number of inhabitants officially exceeded 2,000.
However, poverty was ever-present until well into the 19th century.
There were famines in 1816, 1831 and 1841, and between 1810 and 1890, 651 residents emigrated, mostly to America but also to Africa (the Cape Colony) and Russia (the Caucasus).

Between 1889 and 1891, a road was built connecting Ilsfeld to the administrative center of Besigheim, and in November 1899 a segment of the Bottwar Valley Railway was inaugurated; the following year, this was extended from Ilsfeld to Heilbronn South.
The Royal Württemberg State Railways built the station at Ilsfeld as a unified station of Type IIIa.
The railroad caused Ilsfeld to develop in the early 20th century from a purely rural settlement to a bedroom community for Heilbronn, where more than 200 residents were soon working, mostly in factories such as the Ackermann plying mill, the Knorr soup factory, the Bruckmann silverware factory and the Flammer soap factory.
After an electricity generating plant was built in Pleidelsheim around 1907, Ilsfeld was electrified by 1914.
