What is the role of Atlantis in Plato's Timaeus and Critias?

In Plato's dialogues Timaeus and Critias, Atlantis appears as a powerful naval empire that attempts to conquer ancient Athens. It serves as a fictional allegory for the hubris of nations, contrasting an idealized Athenian state with an aggressive imperial power that ultimately loses divine favor and sinks into the ocean.
