Final answer:
Alexander the Great's military conquests were pivotal in spreading Greek culture, establishing 'Greek-like' Hellenistic civilization across the Middle East by founding Greek cities and promoting Hellenistic culture through the Seleucid and Ptolemaic dynasties.
Step-by-step explanation:
Alexander the Great's influence on the spread of Greek culture to future empires is evident through several key achievements. His military and political successes facilitated the dissemination of Hellenistic culture, effectively blending Greek traditions with those of the conquered lands, forming the new "Greek-like" or Hellenistic civilization. Cities established throughout the Persian Empire, such as those named Alexandria, showcased Greek laws, buildings, and institutions such as temples, theaters, and gymnasia. This cultural integration extended to the use of the Greek language and the setting up of Greek elite classes in various regions. Furthermore, the Seleucid and Ptolemaic dynasties, which arose from Alexander’s generals, continued to promote Greek culture through the use of Greek and Macedonian soldiers and bureaucrats.
