Which Macedonian king founded the city that became Cleopatra's capital?

Alexander the Great founded the city that became Cleopatra's capital: Alexandria in Egypt. The answer refers to the Macedonian king whose conquests reshaped the eastern Mediterranean and Near East.

Alexander founded Alexandria in 331 BC after conquering Egypt from the Persian Empire. He selected a coastal site near the older Egyptian settlement of Rhacotis and envisioned a major Greek city with access to the Mediterranean and the Nile Valley. The architect Dinocrates is traditionally associated with its planned, grid-like layout.

Alexander left Egypt soon after the foundation and never saw the finished city. After his death in 323 BC, his general Ptolemy seized Egypt. Ptolemy I later established the Ptolemaic dynasty and moved the kingdom's capital to Alexandria, where Cleopatra VII ruled nearly three centuries later.

Perdiccas, Demetrius I, and Philip II were all important Macedonian-era figures, but none founded Cleopatra's Alexandria. Ptolemy's dynasty developed the city into a center of trade, scholarship, and Hellenistic culture; Alexander supplied its name and original foundation.
