, ensuring their continued loyalty. This was ensured by the Imperial province of Roman Egypt, which was incredibly wealthy and also the most important grain supplier for the whole empire. Senators were forbidden to even visit this province, as it was largely considered the personal fiefdom of the emperor himself.

Augustus renounced his consulship in 23 BC, but retained his consular imperium, leading to a second compromise between Augustus and the Senate known as the Second Settlement. Augustus was granted the authority of a tribune
Tribune

Tribune was a title shared by 10 elected officials in the Roman Republic. Tribunes had the power to convene the Plebeian Council and to act as its president, which also gave them the exclusive right to propose legislation before it....
 (tribunicia potestas), though not the title, which allowed him to convene the Senate and people at will and lay business before it, veto the actions of either the Assembly or the Senate, preside over elections, and gave him the right to speak first at any meeting. Also included in Augustus's tribunician authority were powers usually reserved for the Roman censor; these included the right to supervise public morals and scrutinise laws to ensure they were in the public interest, as well as the ability to hold a census and determine the membership of the Senate. No tribune of Rome ever had these powers, and there was no precedent within the Roman system for consolidating the powers of the tribune and the censor into a single position, nor was Augustus ever elected to the office of Censor. Whether censorial powers were granted to Augustus as part of his tribunician authority, or he simply assumed these responsibilities, is still a matter of debate.

In addition to tribunician authority, Augustus was granted sole imperium within the city of Rome itself; all armed forces in the city, formerly under the control of the praefects, were now under the sole authority of Augustus. Additionally, Augustus was granted imperium proconsulare maius (power over all proconsuls), the right to interfere in any province and override the decisions of any governor. With maius imperium, Augustus was the only individual able to grant a triumph

All of these reforms were highly unusual in the eyes of Roman republican tradition, but the Senate was no longer composed of the republican patricians who had the courage to murder Caesar.

69–96: Flavian dynasty

The Flavians, although a relatively short-lived dynasty, helped restore stability to an empire on its knees. Although all three have been criticised, especially based on their more centralised style of rule, they issued reforms that created a stable enough empire to last well into the 3rd century. However, their background as a military dynasty led to further marginalisation of the senate, and a conclusive move away from princeps, or first citizen, and toward imperator, or emperor.

 by the senate, he mostly continued the weakening of that body that had been going since the reign of Tiberius. The degree of the Senate's subservience can be seen from the post-dating of his accession to power, by the Senate, to July 1, when his troops proclaimed him emperor, instead of December 21, when the Senate confirmed his appointment. Another example was his assumption of the censorship in 73, giving him power over the make up the Senate. He used that power to expel dissident senators. At the same time, he increased the number of senators from 200, at that low level because of the actions of Nero and the year of crisis that followed, to 1,000; most of the new senators coming not from Rome but from Italy and the urban centers within the western provinces.

Roman Colosseum With Moon
Vespasian was able to liberate Rome from the financial burdens placed upon it by Nero's excesses and the civil wars. To do this, he not only increased taxes, but created new forms of taxation. Also, through his power as censor, he was able to carefully examine the fiscal status of every city and province, many paying taxes based upon information and structures more than a century old. Through this sound fiscal policy, he was able to build up a surplus in the treasury and embark on public works projects. It was he who first commissioned the Amphitheatrum Flavium (Colosseum

s to over three hundred towns and cities, promoting a new era of urbanisation throughout the western (formerly barbarian) provinces. Through the additions he made to the Senate he allowed greater influence of the provinces in the Senate, helping to promote unity in the empire. He also extended the borders of the empire, mostly done to help strengthen the frontier defences, one of Vespasian's main goals.

The crisis of 69 had wrought havoc on the army. One of the most marked problems had been the support lent by provincial legions to men who supposedly represented the best will of their province. This was mostly caused by the placement of native auxiliary units in the areas they were recruited in, a practice Vespasian stopped. He mixed auxiliary units with men from other areas of the empire or moved the units away from where they were recruited to help stop this. Also, to reduce further the chances of another military coup, he broke up the legions and, instead of placing them in singular concentrations, broke them up along the border. Perhaps the most important military reform he undertook was the extension of legion recruitment from exclusively Italy to Gaul

81–96: Domitian
All of the Flavians had rather poor relations with the Senate, because of their autocratic rule, however Domitian was the only one who encountered significant problems. His continuous control as consul and censor throughout his rule; the former his father having shared in much the same way as his Julio-Claudian forerunners, the latter presenting difficulty even to obtain, were unheard of. In addition, he often appeared in full military regalia as an imperator

. His reputation in the Senate aside, he kept the people of Rome happy through various measures, including donations to every resident of Rome, wild spectacles in the newly finished Colosseum, and continuing the public works projects of his father and brother. He also apparently had the good fiscal sense of his father, because although he spent lavishly his successors came to power with a well-endowed treasury.

However, towards the end of his reign Domitian became extremely paranoid, which probably had its initial roots in the treatment he received by his father: although given significant responsibility, he was never trusted with anything important without supervision. This flowered into the severe and perhaps pathological repercussions following the short-lived rebellion in 89 of Lucius Antonius Saturninus

He was forced to submit to their demands, agreeing to hand over those responsible for Domitian's death and even giving a speech thanking the rebellious Praetorians.

Despite early successes against the Sassanian Empire in the East, Alexander Severus's increasing inability to control the army led eventually to its mutiny and his assassination in 235. The death of Alexander Severus ushered in a subsequent period of soldier-emperors and almost a half-century of civil war and strife. Thus the Pax Romana, which had started at the death of Octavian, ended after about 200 years.

235–284: Crisis of the Third Century

The Crisis of the Third Century is a commonly applied name for the crumbling and near collapse of the Roman Empire between 235 and 284. It is also called the period of the "military anarchy".

After Augustus declared an end to the Civil Wars of the 1st century BC, the Empire had enjoyed a period of limited external invasion, internal peace and economic prosperity (the Pax Romana

 of emperors.

Already in the 1st and 2nd century, disputes about the succession had led to short civil wars, but in the 3rd century these civil wars became a constant factor, as no single candidate succeeded in quickly overcoming his opponents or holding on to the Imperial position for very long. Between 235 and 284 no fewer than 25 different emperors ruled Rome (the Soldier-Emperors). All but two of these emperors were either murdered or killed in battle. The organisation of the Roman military, concentrated on the borders, could provide no remedy against foreign invasions once the invaders had broken through. A decline in citizens' participation in local administration forced the Emperors to step in, gradually increasing the central government's responsibility.
