Decisive Moments in History (German: Sternstunden der Menschheit) is a 1927 history book by the Austrian writer Stefan Zweig. It started off with only five miniatures in its first edition and grew to a collection of 14 with later editions. Its first English translation was published in 1940 as The Tide of Fortune: Twelve Historical Miniatures. The miniatures relate historical events that changed the world.
Only the first five miniatures were included in the first edition of the book. The second (German) edition of 1940 added those listed above as numbers 6 through to 12. The last two were added to later German editions but were already part of the first English edition published under the title "The Tide of Fortune: Twelve Historical Miniatures".
