What happened after augustus was named imperator of rome?

In 27 BC, following the Second Triumvirate, Octavian of the Juli was named Augustus by the Roman Senate and given the tile imperator, translated as emperor, which gave him many ruling powers, including the ability to overrule Senators regarding all policy within the Empire. As a result, many recognize this date as the beginning of the Roman Empire being ruled over by an Emperor rather than a Consul as was the case during the Republic. After receiving this title Augustus was able to do as he pleased rebuilding the Roman Forum and city of Rome into a mega center of architecture and grandeur, all while doing so in the name of the restoration of the Republic
