"Everything Olga of Kiev did after her husband was killed by an opposing tribe (the opposing tribe killed him by tying his legs to trees they'd bent down and then releasing the trees)
Cliffs: -Buried 20 men alive -Burning another 20 alive after she'd lured then into a bath house
Slaughtered 5000 of the opposing tribes solders after she'd gotten them piss drunk. -Telling the opposing tribe she'd end the assaults if each house gave her "3 pigeons and 3 sparrows". She then had her soldiers tie sulfur to each of the birds and set them free so that they would return home to nest in their original villages. Eventually the villagers bedtime fires would ignite the sulfur and burn the town to the ground.
Also she's a "saint" in the Orthodox and Roman Catholic church."
All this was loooong before 'we' became a kingdom in it's current form
