The 'Georgenberg Pact' () was signed on
August 17,
1186 on the Georgenberg mountain above
Enns and consisted of two parts. The first part was an agreement between Duke
Ottokar IV of
Styria (from the
Otakars dynasty) and Duke
Leopold V of
Austria (from the
Babenberg dynasty). The childless and deathly ill Ottokar, who had contracted
leprosy while on
crusade, was to give his duchy to Leopold and to his son
Frederick under the stipulation that Austria and Styria would henceforth remain undivided. The second part consists of a delineation of rights of the Styrian estates.
The territory of Styria at the time went far beyond the modern
Styrian state and included lands not only in modern
Slovenia (see
Lower Styria), but also in
Upper Austria, more precisely the
Traungau (the area around
Wels and
Steyr).
The case of succession came to pass in
1192. With the exception of an interlude between
1194 and
1196, Styria has since then remained connected to Austria. The Georgenberg Pact thus was the first step towards the creation of the complex of lands of Austria, which was continued under the
Habsburgs during the
Late Middle Ages.
