Sohrab and Rostam tells the reader a good deal about the history or Iranian culture. When Tahmine meets Rostam she immediately informs him that she would like him to be the father of her baby. Rostam obliges and they purposefully conceive their baby (Sohrab) on the night they meet. All that Rostam knows of Tahmine is the initial beauty that he sees in her, and that she claims she is the Shah’s daughter. In another culture Rostam might reject her advances and accuse her of being a temptress, but through his Iranian heritage Rostam tells her that their child will be great and gives her a jewel for the child complete with instructions, be it a boy or a girl.
In the culture of Iran , Turan, and Semengan it seems that they are taught to seize what they want. Tahmine wants to give birth to Rostam’s baby, so she goes to him and seizes the opportunity. Later in the story when Sohrab has grown, he wants to be with his father and decides that he will seize the crown of Iran and instill his father in the position. He amasses an entire army from Turan, and is willing to move great forces in order to do so. He gives no thought to what the current Shah of Iran will think, or of what the people of either Iran or Turan will think.
