Alexander the Great’s wife who was a Sogdian princess was Roxana.
Roxana was the daughter of Oxyartes, a prominent nobleman associated with Bactria and Sogdiana in Central Asia. Alexander encountered her during his campaigns east of the Persian Empire, after conquering the region and overcoming resistance centered around strongholds such as the Sogdian Rock.
Alexander married Roxana in 327 BC. Ancient sources portray the marriage as romantic, but it also had clear political value: accepting a local aristocratic woman helped Alexander build relationships with Central Asian elites and stabilize his control over recently conquered territory. Roxana later gave birth to Alexander IV, Alexander’s posthumous son.
She is sometimes called Roxane or Roxanna, but these are variant forms of the same name. Cleopatra, Parysatis, and Stateira were connected with Alexander’s wider family and marital history, which can cause confusion. Alexander also married Stateira, the daughter of Persian king Darius III, and Parysatis, a member of the Achaemenid royal family. Roxana, however, was the Central Asian princess who became his first wife.
