Why were these kingdoms called Hellenstic?

The term "Hellenistic" refers to the period following the conquests of Alexander the great, during which Greek culture and influence spread across a vast area, including parts of Europe, Asia, and North Africa. The kingdoms established after Alexander's death, such as the Seleucid, Ptolemaic, and Antigonid kingdoms, were characterized by the blending of Greek and local cultures. This era saw advancements in arts, science, and philosophy, reflecting the fusion of Hellenic and local traditions. Thus, the name "Hellenistic" signifies the widespread dissemination and adaptation of Greek culture during this time.
