Charles Mackay 
Memories Of Extraordinary Popular Delusions Vol.- 2 

Memories Of Extraordinary Common Delusions, Vol. 2 is a book by Charles Mackay that is based on how common beliefs and delusions shaped different events in history. The book is a development of Mackay's earlier work, Extraordinary Popular Delusions and the Madness of Crowds. It covers a wide range of topics, such as the Crusades, witch hunts, and financial bubbles. The book shows how people and groups can get caught up in mass panic and delusions, which can lead to irrational behavior and bad results. Mackay tells in depth about events like the Mississippi Bubble, the South Sea Bubble, and the Tulip Mania, which caused many people to lose all their money. Memories Of Extraordinary Popular Delusions Vol. 2 is an interesting look at how beliefs can change history and give us important information about how the mind works.
