His parents were Count
Albert II of Gorizia and Euphemia of Mätsch. From 1338 to 1365, he ruled Gorizia jointly with his brothers
Albert III and
Henry V, after inheriting the county from their uncle
John Henry IV. From 1362 when Henry V of Gorizia died, he ruled alongside Albert III. From 1365, Meinhard VI ruled Gorizia alone. He failed in a claim over the
County of Tyrol when his second cousin
Margaret was forced to cede Tyrol to
Rudolf IV, Duke of Austria, in 1363. This ended the "dominium Tyrolis" which had existed since 1254. He managed to reduce the power of the
Patriarchate of Aquileia, however, the
Republic of Venice became the beneficiary of the Patriarchate, which led to sharp contrasts between the parties involved. Meinhard retreated from Gorizia Castle to
Burg Bruck (Schloss Bruck) in
Lienz. Meinhard's reign marked the beginning of the decline of the County of Gorizia. The princes of Gorizia had to mortgage and sell more and more of their possessions to salvage their worsening financial position. Meinhard was involved in power struggles with his ecclesiastical neighbours, and in disputes with the
Habsburg dynasty about the succession in the
Duchy of Carinthia and the
County of Tyrol. == Marriages and issue ==
