Q. Did Alexander have a wife?

Yes, as a reward of the Macedonians climbing a huge rock face in Sogdian. The Sogdian tribe laughed when Alexander told them to surrender, but when Alexander got about 300 men to climb the rock, the tribe surrendered and gave to Alexander Roxane as a reward. They got married in 327 B.C.. Alexander got another wife later on, which was one of the the daughter's of Darius.
