Who is Alexander from Plutarch's Lives, Volume 2 and what is their importance?

Alexander was the son of Philip of Macedon. He succeeded his father as king when he was twenty-years-old. Alexander showed promise as a leader from a young age, and his father spared no expense in his education. Over time, Alexander proved himself to be an able military commander and under his leadership, Macedonia conquered much of Persia, where Alexander spread Greek culture and ideas.

Alexander died at the age of thirty-three after a sudden and brief illness. It is believed by some that he was poisoned. Plutarch praises Alexander for his respect for women.
