Brothers Albert I and Maynard IV, counts of Gorizia and Tirol, divide their patrimony, so that Maynard received the County of Tyrol and Albert the County of Gorizia, with the Fort on Mühlbach Pass as the natural border between the two counties.

The original 1267 division of the patrimony of House Gorizia–Tirol between Maynard IV and Albert I unfortunately does not survive in any in extenso manuscript tradition.
Coronini, who must have seen the Latin version of this 1267 charter, erroneously cited “Steyerer Collect. Tom. VI, num. 39”, but in the entire Steyerer collection in the Viennese Haus-, Hof- und Staatsarchiv no such document was found (see Wiesflecker, cited above).
Based on Putsch’s inventory of the Gorizian archive, the 1267 division was preserved only in a “German translation” of the copy (geteutschte = lit. Germanized, translated into German).
While Baum (cited above) is right to infer that the 1267 division was “provisional”, Count Albert I was indeed acting independently of his brother in Friuli already in the second half of 1267 (see Banić, cited above).
The treaty of division was formalized only in 1271, officially sealed by both brothers (see doc. 1271_DG).
