Regency
Princess Olga was the wife of Igor of Kiev, who was killed by the Drevlians. Upon her husband's death, their son, Svyatoslav, was three years old, making Olga the official ruler of Kievan Rus until he reached adulthood. The Drevlians wanted Olga to marry their Prince Mal, making him the ruler of Kievan Rus, but Olga was determined to remain in power and preserve it for her son.
The Drevlians sent twenty of their best men to convince Olga to marry their Prince Mal and give up her rule of Kievan Rus. She had them buried alive. Then she sent word to Prince Mal that she accepted the proposal, but required their most distinguished men to accompany her on the journey in order for her people to accept the offer of marriage. The Drevlians sent their best men who governed their land. Upon their arrival, she offered them a warm welcome and an invitation to clean up after their long journey in a bathhouse. After they entered, she locked the doors and set fire to the building, burning them alive.
With the best and wisest men out of the way, she planned to destroy the remaining Drevlians. She invited them to a funeral feast so she could mourn over her husband's grave, where her servants waited on them. After the Drevlians were drunk, Olga's soldiers killed over 5,000 of them. She returned to Kiev and prepared an army to attack the survivors. The Drevlians begged for mercy and offered to pay for their freedom with honey and furs. She asked for three pigeons and three sparrows from each house, since she did not want to burden the villagers any further after the siege. They were happy to comply with such a reasonable request.
Now Olga gave to each soldier in her army a pigeon or a sparrow, and ordered them to attach by thread to each pigeon and sparrow a piece of sulfur bound with small pieces of cloth. When night fell, Olga bade her soldiers release the pigeons and the sparrows. So the birds flew to their nests, the pigeons to the cotes, and the sparrows under the eaves. The dove-cotes, the coops, the porches, and the haymows were set on fire. There was not a house that was not consumed, and it was impossible to extinguish the flames, because all the houses caught on fire at once. The people fled from the city, and Olga ordered her soldiers to catch them. Thus she took the city and burned it, and captured the elders of the city. Some of the other captives she killed, while some she gave to others as slaves to her followers. The remnant she left to pay tribute.
Olga remained Regent ruler of Kievan Rus with the support of the army and her people. She changed the system of tribute gathering (poliudie) in the first legal reform recorded in Eastern Europe. She continued to evade proposals of marriage, and saved the power of the throne for her son.
