Question

Government under the roman republic or government under the roman empire to be more successful an why

Answer 1

He Roman Republic was what made Rome great. The Roman Empire was what brought about its decline and fall.

When Rome became a Republic in 509BC, Rome's territory consisted of little more than the city itself. Rome was barely more than a collection of villages. By the time the Republic was effectively abolished by Octavian at the end of the 1st century BC, Rome had become a huge empire, as this map shows.
