Why were three kingdoms created from Alexander the Greats empire?

Answer 1

Hellenistic comes from Hellas a.k.a Greece. Historians around the world believe that when Alexander with the other greek cities went against the Persians and the other countries in the east, he brought their advanced greek civilization, culture and language. This is also the reason that the new testimony was written in greek. This is why those kingdoms were called Hellenistic as well as the whole era.

Answer 2

Alexander left no clear heir, and after his death his generals divided up his empire and fought amongst themelves. It eventually settled down to Macedonia, Syria and Egypt.

Answer 3

He left no effective heir, so his generals split up the empire amongst themselves. There were several, which eventually came down to Egypt, Syria, Macedonia and Pergamon.
