Answer: The golden age of Athenian culture is usually dated from 449 to 431 B.C., the years of relative peace between the Persian and Peloponnesian wars. After the second Persian invasion of Greece in 479, Athens and its allies throughout the Aegean formed the Delian League, a military alliance focused on the Persian threat.
Germany had formally surrendered on November 11, 1918, and all nations had agreed to stop fighting while the terms of peace were negotiated. On June 28, 1919, Germany and the Allied Nations (including Britain, France, Italy and Russia) signed the Treaty of Versailles, formally ending the war.
