The Napoleonic Wars caused disruptions where many parts of the Hereditary lands were lost, but all these, along with the former Archbishopric of Salzburg, which had previously been temporarily annexed between 1805 and 1809, were recovered at the peace in 1815, with the exception of the Vorlande.
Napoleoni sõjad põhjustasid segadust, kus paljud osad pärusvaldustest kaotati, kuid kõik need, koos endise Salzburgi peapiiskopkonnaga, mis varemalt oli aastatel 1805–1809 ajutiselt annekteeritud, saadi 1815. aasta rahulepinguga tagasi, v.a Vorlande.
