Zbigniew sees the marriage of Boleslaw to …

Years: 1105 - 1105

Zbigniew sees the marriage of Boleslaw to a princess from Rus' and an alliance with Kiev as a serious threat.

He therefore prevails upon his ally, Borivoj II of Bohemia, to invade Boleslaw’s province.

Boleslaw retaliates with expeditions into Pomerania in 1104–1105, which bring the young prince not only loot, but also effectively disintegrates the alliance of Pomeranians and Zbigniew.

Boleslaw’s partnership with King Coloman of Hungary, whom he had aided in gaining the throne, bears fruit in 1105 when they successfully invade Bohemia.

Also in 1105, Boleslaw enters into an agreement with his stepmother Judith of Swabia, the so-called Tyniec Accord.

According to their agreement, in exchange for a generous grant, the prince is guaranteed Judith's neutrality in his political contest with Zbigniew.
