Both the Roman Republic and the Roman Empire have unstable times, and eventually they have died. Interestingly, as each period is about the same, it is difficult to confirm that one is "succeeding" the other. But given the extent of the Roman Empire after the collapse of the Western Empire and its continuation from Byzantine, the Empire is finally more successful than the Republic.

The Republic of Rome dominated the majority of the Italian peninsula, and soon spread to the Mediterranean. In conflict with the Phoenicians, it was about Sicilian colonization and control. The Romans won all three Poeni wars, but they were expensive and those who took part in the war abandoned their houses and destroyed the farm. They sold the farm to several wealthy citizens and lost their voting rights. The final result was a civil war, followed by the slave riots led by Spartacus, some of which raised a private army including Gaius Julius Caesar. This dying republic was dominated by the famous Big Three for a short time; with the deaths of Krassu and Caesar it quickly collapsed and became the first Roman Emperor.

The empire itself no longer sustains for the Republic but its territory's benefit is quite extensive. The Republic is restricted to the Italian peninsula and the Mediterranean (the Romans call it a horse: "Our Ocean"), the Empire is not only in the east of the Rhine and the Danube, but also in the western part of England Also spread. The vast majority of people, thus spreading Roman culture throughout Western Europe. With this alone, you may think that the Empire is more successful than the Republic. You should think that a vast range of empires has brought its division to the East and the West Empire; even after the collapse of the Western Empire in 476, the Eastern Empire continues, Constantinople falls into Turks in 1453 It was a great success.

The constitutional history of the Roman Republic began in 509 when it ended with the amendment of the Constitution. It changed the Republic into a real Roman Empire in 27 years. The Constitution of the Republic of Rome is constantly evolving, and the written guidelines and principles are largely precedent, taken over by the government and its political activities. Throughout the history of the Republic, changes in the Constitution are caused by conflicts of interest between aristocrats and the general public.

Both the Roman Republic and the Roman Empire have unstable times, and eventually they have died. Interestingly, as each period is about the same, it is difficult to confirm that one is "succeeding" the other. However, considering the size of the Roman Empire and the continuation from Byzantium after the collapse of the Western Empire, the Empire eventually succeeded more than the Republic. The Republic of Rome dominated the majority of the Italian peninsula, and soon spread to the Mediterranean. In conflict with the Phoenicians, it was about Sicilian colonization and control. The Romans won all three Poeni wars, but they were expensive and those who took part in the war abandoned their houses and destroyed the farm.
