Read each passage carefully. Why did the historical account of the Viking change? In 1889, researchers discovered a person who was buried in Birka, Sweden. Birka is one of Sweden’s greatest Viking sites. It was an important Viking trading center. Birka had over 3,000 graves. This grave contained a single human, two horses, and weapons. Researchers wrote that the Viking was a wealthy male warrior because he had so many possessions. Researchers in Sweden decided to conduct testing on an individual buried in a famous Viking grave. The grave is known as Bj 581. This grave contains a single human, two horses, and weapons. Scientists reexamined the body in 1970. They studied the shape of the hips. The shape seemed to be female. This claim stirred up a controversy. Could Viking warriors be women? In 2017, scientist Charlotte Hedenstierna-Jonson analyzed ancient DNA from Bj 581. The results were conclusive. The Viking in the grave was female.
