добрые люди, помогите пожалуйста, нет сил самому осилить текст - The first piece of evidence that I have is The Achievements of the Divine Augustus, which states all of the achievements and accomplishments that helped him conquer the world under the Roman Empire. In this piece of evidence it shows all of Caesar Augustus’ tactics he used to help him conquer the world. Many of which were war related. He gained most of his power by going to war and overthrowing that particular ruler. Thus this helped him gain respect which was also a key factor in his dominance. Once gaining the respect of the Roman Senate and also the republic he became the top runner to be «elected sole guardian of the laws and moral with supreme authority». But Augustus refused to take that role of leadership in the Empire. He did many things in which the people love such as repairing the capitol and the theater of Pompey which cost a great amount and he did it without any public recognition. He did a number of things to help out the ruins and made the cities better by rebuilding them and making them nice again. Also what he wasn’t going to finish by his death he would make sure his heirs would complete it. This list goes on and on of things that Augustus had done to help out the lives of people under the Roman Empire. This piece of evidence showed the strength that Roman Empire would soon have because they were still on the rise. The second piece of evidence that I have is Powers and Titles of the Emperor. This was a key part of having a successful empire. Once the Roman Empire was established they thought up a hierarchy to help control the empire. The good thing that came out of this was that the senate and the republic agreed to pass all the power entirely to Augustus. Now that they had a good ruler, it showed that their empire was growing and was a very strong for to be reckoned with. With such a high status Augustus and his successors expected a lot of support from the people and from the Roman senate. Кто может, ПОМОГИТЕ!!!
