A century followed during which Roman rule was extended and consolidated over the whole area of the countries fringing the Mediterranean, while concurrently a long series of revolutions and counter-revolutions ended in the overthrow of the republican oligarchy, and the establishment of the imperial government. Beginning with the democratic movement of the Gracchi, this century includes the civil wars of Marius and Sulla, the temporary reconstitution of the oligarchy, the renewed outbreak of war between Julius Caesar and the senate, and the confused period of administrative anarchy which was terminated by the rise of Augustus to a practical dictatorship, and the arrangement by him of a working compromise between the two great opposing forces. During this century of revolution the whole attitude of Rome towards the problems both of internal and of foreign politics was forced through a series of important changes. The revolt of Italy, which, after bringing Rome to the verge of destruction, was finally crushed by the Asiatic legions of Sulla, was almost immediately followed by the unification of Italy, and her practical absorption into the Roman citizenship. With renewed and enlarged life, Rome then entered on a second extension of her dominions. The annexation of Syria and the conquest of Gaul completed the circle of her empire; the subjugation of Spain was completed, and the Eastern frontier pushed towards Armenia and the Euphrates; finally Egypt, the last survivor of the kingdoms founded by Alexander's generals, passed wholly into Roman hands with the extinction of its own royal house.
