It changed into the empire.. first it became a republic because the Romans wants voice). freedom from the kings. so they created the roman republic(which gave them a voice). Then Julius Caesar stopped the roman republic. he became a sole ruler. When the politics killed him, his son Octavian( which he named himself Augustus), became in charge. Under Augustus rules, Rome became an empire Octavian was actually his nephew not his son, While Caesar did have a son with Cleopatra he died at a young age though I am not sure when. Caesar Implemented what he called "Bread and Circuses" Which basically meant "As long as you can keep people fed and entertained you can take away all of their freedoms." So while Caesar kept the people fed and held constant games in the Colusseum he <span>slowly began turning what was once a Republic into an Empire.</span>
The impact of Hellenism on the jews can be traced chronogically from the time of Alexander,the great to the destruction of the temple in 70 AD.This is because as a result of the conquests of Alexander, the history, culture, languages and civilizations of the peoples of the eastern Mediterranean and Asia were changed forever.
Hope That Helps!
