2. After which event in Greek history, one that caused much destruction in the polis of Athens, was the Erechtheion constructed?
From Quiz Tales of Caryatids
Answer:
Second Persian War
During the Second Persian War, the Athenains had been unable to protect their city from attack. The Persians destroyed or damaged many of the public buildings, and, by the end of the war, several needed to be rebuilt. With the war over, the Greeks decided to form the Delian League in order to protect their country from future attack. Athens was chosen to be the leader of the League, and decided to use the money, paid as tribute by other members of the League for the mutual protection of Greece, from the group's treasury to rebuild their city. The Erechtheion was constructed from 421-406 BC; although its original use is not known, historians believe that it was built to either honor the legendary Erichtonius, who was said to have invented the four horse chariot and also taught the ancients how to plow the soil and smelt silver, or King Erechtheus, who some believe was the founder of Athens.
