What territories did alexander the great conquered?

Alexander the Great conquered many territories, mainly in these locations: Egypt, The middle east, Central Asia, and Greece. He was the student of Aristotle, and brought many cultures together for the brief time he ruled. Evidence of this cultural-mixing is still present to this day! After his death, the kingdoms and territories he conquered slowly dissolved to the point of becoming independent of the generals that ruled over them.
