Final answer:
Without specific context, it's challenging to determine why a leader would return to Athens with supreme authority and the reasons behind his acceptance and subsequent rejection. Athenian democracy allowed for the participation of citizens in governance, and political fortunes could change rapidly based on various pressures including military, political, and social factors.
Step-by-step explanation:
The scenario you’re describing sounds like it involves an Athenian leader returning to Athens with authority, being welcomed back, and then later being rejected again. This sequence of events is reminiscent of historical figures like Alcibiades during the Peloponnesian War, however, the details provided do not align perfectly with Alcibiades’ story or any specific figure. Thus, without a specific name or event, it is challenging to provide a factually accurate answer.
Generally, in Athenian democracy citizens had significant participation in governance, which may involve electing a former leader in times of need. Athenians often rallied behind strong leaders, especially those who had a history of successful military or political leadership, due to the belief in their ability to navigate crises. However, political tides could turn quickly, with leaders facing rejection if they failed to meet expectations or uphold democratic values.
To thoroughly answer your question, it would be essential to have more contextual information about the specific individual or period you’re referring to. Athens’ democracy was dynamic and the fortunes of its leaders, as well as their relationships with the populace, were subject to change due to political, military, and social pressures.
