What you're overlooking is that Miller made two mistakes!
First off, he was expecting the literal end of the world; but this is because of a mistake made by the compilers of the KJV Bible: the original Greek word is "eras," which means "world" or "age." And the translators picked the wrong meaning: what the prophecy is really about is the end of the Age!
Are you talking about the coming of the Age of Aquarius? In that case, the earliest claim of it coming was in 1884, with the arrival of Babism which eventually turned into the Baha'i Faith after a few mutinies and internal struggles. However there are more claims that the Age of Aquarius actually arrived sometime in the 20th century (I am among the ones who believe this, more specifically, I believe it was in the late 1900's).
Aquarius traditionally "rules" electricity, computers, flight, democracy, freedom, humanitarianism, idealists, modernization, astrology, nervous disorders, rebels and rebellion, nonconformity, philanthropy, veracity, perseverance, humanity and irresolution. As for the rise and fall of empires, the USA is on the verge of collapse, and some think that China has risen as a/the new empire.
