Define the roman republic and list the major concepts of the roman republic

In the late 6th century BCE, the small city-state of Romeoverthrew the shackles of monarchy and created a republican government that, in theory if not always in practice, represented the wishes of its citizens. From this basis the city would go on to conquer all of the Italian peninsula and large parts of the Mediterraean world and beyond. The Republic and its insitutions of government would endure for five centuries, until, wrecked by civil wars, it would transform into a Principate ruled by emperors.  Even then many of the politcal bodies, notably the Senate, created in the Republican period would endure, albeit with a reduction in power.

The years prior to the rise of the Republic are lost to myth and legend. No contemporary written history of this period has survived. Although much of this history had been lost, the Roman historian Livy (59 BCE – 17 CE) was still able to write a remarkable History of Rome  - 142 volumes -  recounting the years of the monarchy through the fall of the Republic. Much of his history, however, especially the early years, was based purely on myth and oral accounts. Contrary to some interpretations, the fall of the monarchy and birth of the republic did not happen overnight.  Some even claim it was far from bloodless. Historian Mary Beard in her SPQR wrote that the transformation from monarchy to republic was “borne over a period of decades, if not, centuries.”

Prior to the overthrow of the last king, Tarquinius Superbus or Tarquin the Proud in 510 BCE, the history of the city is mired in stories of valor and war. Even the founding of the city is mostly legend and many people have preferred the myth over fact anyway. For years Rome had admired the Hellenistic culture of the Greeks, and so it easily embraced the story of Aeneas and the founding of Rome as penned by Roman author Virgil in his heroic saga The Aeneid. This story gave the Romans a link to an ancient, albeit Greek, culture. This mythical tale is about Aeneas and his followers who, with the assistance of the goddess Venus, escaped the city of Troy as it fell to the Greeks in the Trojan War. Jupiter’s wife Juno constantly interfered with the story's hero Aeneas throughout the tale. After a brief stay in Carthage, Aeneas eventually made his way to Italy and Latium, finally fulfilling his destiny. His descendants were the twins Romulus and Remus - the illegitimate sons of Mars, the god of war, and the princess Rhea Silvia, the daughter of the true king of Alba Longa.  Rescued from drowning by a she-wolf and raised by a shepherd, Romulus eventually defeated his brother in battle and founded the city of Rome, becoming its first king. So the legend goes.
