Just to note that this title and subtitle seem quite misleading, even tho it is clarified in the article itself that it’s a first for the Carpathian basin and the timeframe of the 10th century. I noticed this happening for many other outlets as well, if not most. Still, thanks OP for sharing this, good to know!

For the 10th century there is at least this one more that is well known for years now:

Birka grave Bj 581 held a female Viking warrior buried with weapons during the 10th century in Birka, Sweden.

Similar burial sites through time and all over the world:

• Archaeologists unearth graves of ancient warrior women in Russia - The find suggests there may be truth behind legends of Amazons
• Ancient burial of fierce female hunter (and her weapons) discovered in Peru
• Women in ancient warfare - this wiki covers many-many centuries, though perhaps not thoroughly updated.
