The satrapic administration and title were retained—even for Greco-Macedonian incumbents—by Alexander the Great, who conquered the Achaemenid Empire, and by his successors, the Diadochi (and their dynasties) who carved it up, especially in the Seleucid Empire, where the satrap generally was designated as strategos (in other words, military generals); but their provinces were much smaller than under the Persians. They would ultimately be replaced by conquering empires, especially the Parthians.
