The Birka Islands in Sweden were originally excavated in the 1800s. At the top of a hill, located away from the main burials and near an armory was the grave Bj. 581. Initially marked by a giant stone, that would have been visible from the sea, where the many merchants and traders that came to the Birka islands would have gazed upon. The grave of a wealthy-warrior WOMAN. 

For more than 140 years this grave was accepted as a man's grave until in 2017 her bones were DNA tested as part of a large collection of items. The researchers were astonished to find that the bones (clearly marked with Bj. 581) had a set of two X-chromosomes and was female! 

This woman was buried with two horses a mare and a stallion, two shields, a large number of weapons including more than 20 arrows and a hatchet- and most incredibly a full set of gaming pieces in her lap, which may indicate her as a high-commander. After the discovery of her scandalous double X-chromosomes, several objections went up against the discovery, some saying that they may have tested the wrong bones, others saying that she was just buried with copious amounts of weapons and that they may not reflect her life in the slightest. All of this can generally be proved to be incorrect, the bones tested were clearly marked, Stope's sketches of the grave show only one person buried there, it is highly unlikely that a person of little importance and no hand in weaponry would be buried with such a collection of items. 

These doubts come from a place of pure bias and misogyny. Neither of which have any space in the cultures of the past.
