Please answer the following question: Information: - The Roman army (Latin: ) is a term that can in general be applied to the terrestrial armed forces deployed by the Romans throughout the duration of Ancient Rome, from the Roman Kingdom (to c. 500 BC) to the Roman Republic (50031 BC) and the Roman Empire (31 BC 395/476 AD), and its successor the East Roman or Byzantine Empire. It is thus a term that may span approximately 2,000 years, during which the Roman armed forces underwent numerous permutations in composition, organisation, equipment and tactics, while conserving a core of lasting traditions. - Tribunus, in English tribune, was the title of various elected officials in Ancient Rome. The two most important were the tribunes of the plebs and the military tribunes. For most of Roman history, a college of ten tribunes of the plebs acted as a check on the authority of the senate and the annual magistrates, holding the power of "ius intercessionis" to intervene on behalf of the plebeians, and veto unfavourable legislation. There were also military tribunes, who commanded portions of the Roman army, subordinate to the higher magistrates, such as the consuls and praetors, promagistrates, and their legates. Various officers within the Roman army were also known as tribunes. The title was also used for several other positions and classes in the course of Roman history. - The Roman Senate was a political institution in ancient Rome. It was one of the most enduring institutions in Roman history, being established in the first days of the city (traditionally founded in 753 BC). It survived the overthrow of the kings in 509 BC, the fall of the Roman Republic in the 1st century BC, the division of the Roman Empire in 395 AD, the fall of the Western Roman Empire in 476 AD, and the barbarian rule of Rome in the 5th, 6th, and 7th centuries. - The Scordisci were a Gallic Iron Age tribe centered in the territory of present-day Serbia, at the confluence of the Savus (Sava), Dravus (Drava) and Danube rivers. They were historically notable from the beginning of the third century BC until the turn of the common era. The Scordisci consolidated into a tribal state. At their zenith, their core territory stretched over regions comprising parts of present-day Serbia, Croatia, Bulgaria and Romania, while their influence spread even further. After the Roman conquest in the 1st century AD, their territories were included into the Roman provinces of Pannonia, Moesia and Dacia. - Pannonia was an ancient province of the Roman Empire bounded north and east by the Danube, coterminous westward with Noricum and upper Italy, and southward with Dalmatia and upper Moesia. Pannonia was located over the territory of the present-day western Hungary, eastern Austria, northern Croatia, north-western Serbia, northern Slovenia, western Slovakia and northern Bosnia and Herzegovina. - Gaius Sempronius Gracchus (154121 BC) was a Roman "Popularis" politician in the 2nd century BC and brother of the reformer Tiberius Sempronius Gracchus. His election to the office of tribune in the years 123 BC and 122 BC and reformative policies while in office prompted a constitutional crisis and his death at the hands of the Roman Senate in 121 BC. - In ancient Rome a promagistrate was an ex consul or ex praetor whose imperium (the power to command an army) was extended at the end of his annual term of office or later. They were called proconsuls and propraetors. This was an innovation created during the Roman Republic. Initially it was intended to provide additional military commanders to support the armies of the consuls (the two annually elected heads of the Republic and its army) or to lead an additional army. With the acquisitions of territories outside Italy which were annexed as provinces, proconsuls and propraetors became provincial governors or administrators. A third type of promagistrate were the proquaestors. - The Iron Age is an archaeological era, referring to a period of time in the prehistory and protohistory of the Old World (Afro-Eurasia) when the dominant toolmaking material was iron. It is commonly preceded by the Bronze Age in Europe and Asia with exceptions and the Stone Age in Africa. Meteoric iron has been used by humans since at least 3200 BC, but ancient iron production did not become widespread until the ability to smelt iron ore, remove impurities and regulate the amount of carbon in the alloy were developed. The start of the Iron Age proper is considered by many to fall between around 1200 BC to 600 BC, depending on the region. In most parts of the world, its end is defined by the widespread adoption of writing, and therefore marks the transition from prehistory to history. - The elder Marcus Livius Drusus ( died 108 BC ) was set up as tribune by the Senate in 121 BC to undermine Gaius Gracchus ' land reform bills . To do this ( according to the record of Appian ) , he proposed creating twelve colonies with 3,000 settlers each from the poorer classes , and relieving rent on property distributed since 133 BC. He also said the Latin allies should not be mistreated by Roman generals , which was the counteroffer to Gaius ' offer of full citizenship . These were known as the Leges Liviae , but they were never enacted , because the Senate simply wanted to draw support away from Gracchus . Their plan was successful and Drusus had enough support to veto Gaius ' bill . Drusus was later consul in 112 BC and fought in Macedonia defeating the Scordisci , even pushing them out of Thrace across the Danube . In 109 BC he was elected censor along with the elder Marcus Aemilius Scaurus , but he died the next year in 108 BC. He had a son of the same name , whose murder incited the Italian Social War . After reading the paragraphs above, choose the best answer for the entity that related to 'marcus livius drusus ' with the relationship of 'period'. Choices: - bronze age - iron age - roman empire - roman republic
Answer:
roman republic
