Answer
Yes, Lysimachus ruled over part of modern-day Turkey. He was one of the generals of Alexander the Great, and after Alexander's death he became one of the Diadochi, or successors to Alexander's empire. Lysimachus ruled over a large territory that included parts of modern-day Turkey, Greece, and Bulgaria. He was eventually killed in battle in 281 BC, and his empire was divided up among his successors.
