Olga of Kiev
Sometime around 903 CE, Olga married Prince Igor. In an ideal world they would have lived happily ever after.
After Igor took power, the Drevlian tribe decided to stop paying tribute to Igor despite having paid the tribute to his tribe in the past. Igor traveled to the Drevlians with a large contingent of men and was paid. After Igor left, he decided it wasn’t enough money, so he returned with a smaller contingent for more money.
