Step-by-step explanation:
After Alexander the Great died, two empires emerged: the Seleucid Empire and the Ptolemaic Kingdom.
The Seleucid Empire was known for its Hellenistic culture. It was founded by Seleucus, one of Alexander's generals. This empire extended from present-day Turkey to Afghanistan and included diverse populations and cultures. The Seleucids ruling this empire adopted Greek and Persian customs, built Greek cities, and engaged in trade with India and other parts of the world.
The Ptolemaic Kingdom, on the other hand, was established in Egypt by Ptolemy, another of Alexander's generals. It was centered in Alexandria, which became a major center of learning and trade. The Ptolemies maintained a hybrid Greco-Egyptian culture, combining Greek and Egyptian customs. They also built extensive agricultural infrastructure, such as irrigation systems, to support their trade and economy.
