Explanation:
Pericles was a great speaker, a quality that allowed him to succeed with his word in the Assembly, exposing his vision of politics. One of his greatest successes was to get access to the positions of public official to Athenian citizens called thetaz, who were those who lacked wealth. Another great success of his government was the institution of the mistoforia; that is, a special salary for civil servants who attended the Assembly. In this way these citizens lost nothing even if they had to dedicate themselves completely to these public positions. With this system Pericles managed that the Assembly was always full of assistants. As governor of Athens he managed to make this city the first and the most important in the Greek world, acquiring democratic institutions.
