Seljuks and Normans

A Western army invades a Middle Eastern country, relying on superior military technology to “shock and awe” a numerically superior Muslim opponent. After achieving a seemingly decisive victory the triumphant invaders set out to build a new state based on the prevailing European political model. The commander of the invading force then marries off his sister to an enemy warlord. When the warlord dies in battle, she flees to Eastern Anatolia, declaring herself regent for a newborn son whose Turkmen Atabeg she marries.
