Historical Information and Dates Conditions under which the citizens of the Roman Republic had to live . The beginning of the first century BC was not the most successful period for the Roman Republic (McCarty 56). The development of the political crisis made the vast majority of leaders proved their powers and abilities to be supported by the citizen and get the necessary positions to rule the world. Still, it was hard to define those powers were more appropriate to the conditions under which the Romans had to live. There were three evident leaders during the period under analysis: Marcus Licinius Crassus, Gaius Julius Caesar, and Gnaeus Pompeius Magnus (Leoni 42). To provide favorable conditions for Rome, these three people signed the political alliance known as the First Triumvirate; and though this step did not have some official status, it was an influential step in the history. However, the death of one of the leaders, Crassus, changed considerably the development of the events as a result of which, Caesar and Pompeius found it obligatory to get power due to their own achievements and possibilities. In fact, it was evident that certain changes had to be made to define the leader and distribute powers. Events before the Battle of Pharsalus . Caesar and Pompeius could not reach the necessary agreement to divide their powers in Rome, this is why they decided to start a fight at the end of which the citizens could see whose powers were greater.

The authority of Pompeius was justified by his activities during the war with Spain in 77 th BC. Though he did not achieve the desirable laurels, he understood his personal priority and abilities to convince people around. Within a short period of time, Pompeius gained recognition in the East, celebrated his victory in the Temple of Jerusalem, and returned to Rome as a definite leader. In his turn, Caesar was known as one of the most thoughtful and artful figure in the history. Before the First Triumvirate, Caesar’ activities with Catilina demonstrated how mature his actions could be in order to gain the desirable power. Frankly speaking, the backgrounds of the two leaders were great indeed, and both of them had special priorities in particular spheres which made them the two worthy opponents to each other. What the two great leaders fought for . In fact, the purpose of why Caesar and Pompeius supported the idea of was similar: to get the power of the Roman citizens and conquer the whole world (Leoni 43).
