Question: What marked the end of where the system of representative government came from?

full_context: Document 1: Direct democracy: The earliest known direct democracy is said to be the Athenian democracy in the 5th century BC, although it was not an inclusive democracy: women, foreigners, and slaves were excluded from it. The main bodies in the Athenian democracy were the assembly, composed of male citizens; the boulê, composed of 500 citizens; and the law courts, composed of a massive number of jurors chosen by lot, with no judges. There were only about 30,000 male citizens, but several thousand of them were politically active in each year, and many of them quite regularly for years on end. The Athenian democracy was direct not only in the sense that decisions were made by the assembled people, but also in the sense that the people through the assembly, boulê, and law courts controlled the entire political process, and a large proportion of citizens were involved constantly in the public business. Modern democracies, being representative, not direct, do not resemble the Athenian system.
Document 2: Roman Republic: The Roman Republic (Latin: Res publica Romana; Classical Latin: [ˈreːs ˈpuːb.lɪ.ka roːˈmaː.na]) was the period of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world. During the first two centuries of its existence, the Roman Republic expanded through a combination of conquest and alliance, from central Italy to the entire Italian peninsula. By the following century, it included North Africa, Spain, and what is now southern France. Two centuries after that, towards the end of the 1st century BC, it included the rest of modern France, Greece, and much of the eastern Mediterranean. By this time, internal tensions led to a series of civil wars, culminating with the assassination of Julius Caesar, which led to the transition from republic to empire. The exact date of transition can be a matter of interpretation. Historians have variously proposed Julius Caesar's crossing of the Rubicon River in 49 BC, Caesar's appointment as dictator for life in 44 BC, and the defeat of Mark Antony and Cleopatra at the Battle of Actium in 31 BC. However, most use the same date as did the ancient Romans themselves, the Roman Senate's grant of extraordinary powers to Octavian and his adopting the title Augustus in 27 BC, as the defining event ending the Republic.
Document 3: Religion in ancient Rome: Rome's government, politics and religion were dominated by an educated, male, landowning military aristocracy. Approximately half Rome's population were slave or free non-citizens. Most others were plebeians, the lowest class of Roman citizens. Less than a quarter of adult males had voting rights; far fewer could actually exercise them. Women had no vote. However, all official business was conducted under the divine gaze and auspices, in the name of the senate and people of Rome. "In a very real sense the senate was the caretaker of the Romans’ relationship with the divine, just as it was the caretaker of their relationship with other humans".
Document 4: Rome: Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by some as the first ever metropolis. It was first called "The Eternal City" (; ) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called the "Caput Mundi" (Capital of the World). After the fall of the Western Empire, which marked the beginning of the Middle Ages, Rome slowly fell under the political control of the Papacy, and in the 8th century it became the capital of the Papal States, which lasted until 1870. Beginning with the Renaissance, almost all the popes since Nicholas V (1447–1455) pursued over four hundred years a coherent architectural and urban programme aimed at making the city the artistic and cultural centre of the world. In this way, Rome became first one of the major centres of the Italian Renaissance, and then the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters, sculptors and architects made Rome the centre of their activity, creating masterpieces throughout the city. In 1871, Rome became the capital of the Kingdom of Italy, which, in 1946, became the Italian Republic.
Document 5: Roman Republic: Citizens were organized on the basis of centuries and tribes, which would each gather into their own assemblies. The Comitia Centuriata ("Centuriate Assembly") was the assembly of the centuries (i.e. soldiers). The president of the Comitia Centuriata was usually a consul. The centuries would vote, one at a time, until a measure received support from a majority of the centuries. The Comitia Centuriata would elect magistrates who had imperium powers (consuls and praetors). It also elected censors. Only the Comitia Centuriata could declare war, and ratify the results of a census. It also served as the highest court of appeal in certain judicial cases.
Document 6: Athenian democracy: It was a system of direct democracy, in which participating citizens voted directly on legislation and executive bills. Participation was not open to all residents: to vote one had to be an adult, male citizen, i.e., not a foreign resident, a slave or a woman, and the number of these was ``probably no more than 30 percent of the total adult population. ''
Document 7: Roman Republic: The senate's ultimate authority derived from the esteem and prestige of the senators. This esteem and prestige was based on both precedent and custom, as well as the caliber and reputation of the senators. The senate passed decrees, which were called senatus consulta. These were officially "advice" from the senate to a magistrate. In practice, however, they were usually followed by the magistrates. The focus of the Roman senate was usually directed towards foreign policy. Though it technically had no official role in the management of military conflict, the senate ultimately was the force that oversaw such affairs. The power of the senate expanded over time as the power of the legislative assemblies declined, and the senate took a greater role in ordinary law-making. Its members were usually appointed by Roman Censors, who ordinarily selected newly elected magistrates for membership in the senate, making the senate a partially elected body. During times of military emergency, such as the civil wars of the 1st century BC, this practice became less prevalent, as the Roman Dictator, Triumvir or the senate itself would select its members.
Document 8: Southern Europe: The Roman Empire came to dominate the entire Mediterranean basin in a vast empire based on Roman law and Roman legions. It promoted trade, tolerance, and Greek culture. By 300 AD the Roman Empire was divided into the Western Roman Empire based in Rome, and the Eastern Roman Empire based in Constantinople. The attacks of the Germanic peoples of northern Europe led to the Fall of the Western Roman Empire in AD 476, a date which traditionally marks the end of the classical period and the start of the Middle Ages.
Document 9: Roman Empire: The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empire's existence were a period of unprecedented political stability and prosperity known as the Pax Romana, or ``Roman Peace ''. Following Octavian's victory, the size of the empire was dramatically increased. After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. After Claudius' successor, Nero, committed suicide in AD 68, the empire suffered a series of brief civil wars, as well as a concurrent major rebellion in Judea, during which four different legionary generals were proclaimed emperor. Vespasian emerged triumphant in AD 69, establishing the Flavian dynasty, before being succeeded by his son Titus, who opened the Colosseum shortly after the eruption of Mount Vesuvius. His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The Senate then appointed the first of the Five Good Emperors. The empire reached its greatest extent under Trajan, the second in this line.
Document 10: Mediterranean Sea: Two of the most notable Mediterranean civilizations in classical antiquity were the Greek city states and the Phoenicians, both of which extensively colonized the coastlines of the Mediterranean. Later, when Augustus founded the Roman Empire, the Romans referred to the Mediterranean as Mare Nostrum (``Our Sea ''). For the next 400 years, the Roman Empire completely controlled the Mediterranean Sea and virtually all its coastal regions from Gibraltar to the Levant.
Document 11: Roman Republic: The Roman Republic (Latin: Res publica Romana; Classical Latin: (ˈreːs ˈpuːb. lɪ. ka roːˈmaː.na)) was the era of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world.
Document 12: Roman Republic: The assembly of the tribes (i.e. the citizens of Rome), the Comitia Tributa, was presided over by a consul, and was composed of 35 tribes. The tribes were not ethnic or kinship groups, but rather geographical subdivisions. The order that the thirty-five tribes would vote in was selected randomly by lot. Once a measure received support from a majority of the tribes, the voting would end. While it did not pass many laws, the Comitia Tributa did elect quaestors, curule aediles, and military tribunes. The Plebeian Council was identical to the assembly of the tribes, but excluded the patricians (the elite who could trace their ancestry to the founding of Rome). They elected their own officers, plebeian tribunes and plebeian aediles. Usually a plebeian tribune would preside over the assembly. This assembly passed most laws, and could also act as a court of appeal.
Document 13: Representative democracy: The Roman Republic was the first government in the western world to have a representative government, despite taking the form of a direct government in the Roman assemblies. The Roman model of governance inspired many political thinkers over the centuries, and today's modern representative democracies imitate more the Roman than the Greek models because it was a state in which supreme power was held by the people and their elected representatives, and which had an elected or nominated leader. Representative democracy is a form of democracy in which people vote for representatives who then vote on policy initiatives as opposed to a direct democracy, a form of democracy in which people vote on policy initiatives directly. A European medieval tradition of selecting representatives from the various estates (classes, but not as we know them today) to advise / control monarchs led to relatively wide familiarity with representative systems inspired by Roman systems.
Document 14: Roman Empire: The Roman Empire (Latin: Imperium Rōmānum, Classical Latin: (ɪmˈpɛ. ri. ũː roːˈmaː. nũː); Koine and Medieval Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tōn Rhōmaiōn) was the post-Roman Republic period of the ancient Roman civilization, with a government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world c. 100 BC -- c. AD 400, with Constantinople (New Rome) becoming the largest around AD 500, and the Empire's population grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500 - year - old republic which preceded it had been severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title Augustus, effectively marking the end of the Roman Republic.
Document 15: Direct democracy: Direct democracy was not what the framers of the United States Constitution envisioned for the nation. They saw a danger in tyranny of the majority. As a result, they advocated a representative democracy in the form of a constitutional republic over a direct democracy. For example, James Madison, in Federalist No. 10, advocates a constitutional republic over direct democracy precisely to protect the individual from the will of the majority. He says,
