Broke and losing the war

“If any ventured to rise in opposition, he was presently put to death in some convenient way, and there was neither search for the murderers nor justice to be had against them if suspected; but the people remained motionless, being so thoroughly cowed that men thought themselves lucky to escape violence, even when they held their tongues…. it was impossible for any one to open his grief to a neighbour and to concert measures to defend himself, as he would have had to speak either to one whom he did not know, or whom he knew but did not trust.” — Thucydides, The History of the Peloponnesian War, Ch. XXVI (trans. Crawley), regarding the overthrow of Athenian democracy

Earthquake and tsunami (Humean constant conjunction)

“The next summer the Peloponnesians and their allies set out to invade Attica under the command of Agis, son of Archidamus, and went as far as the Isthmus, but numerous earthquakes occurring, turned back again without the invasion taking place. About the same time that these earthquakes were so common, the sea at Orobiae, in Euboea, retiring from the then line of coast, returned in a huge wave and invaded a great part of the town, and retreated leaving some of it still under water; so that what was once land is now sea; such of the inhabitants perishing as could not run up to the higher ground in time. A similar inundation also occurred at Atalanta, the island off the Opuntian Locrian coast, carrying away part of the Athenian fort and wrecking one of two ships which were drawn up on the beach. At Peparethus also the sea retreated a little, without however any inundation following; and an earthquake threw down part of the wall, the town hall, and a few other buildings. The cause, in my opinion, of this phenomenon must be sought in the earthquake. At the point where its shock has been the most violent, the sea is driven back and, suddenly recoiling with redoubled force, causes the inundation. Without an earthquake I do not see how such an accident could happen.” — Thucydides, The History of the Peloponnesian War, Ch. XI (trans. Crawley)
