Alternate history and a Scandinavian England

What are the panel's favorite unusual alternate-history timelines?

A Scandinavian conquest of England stands out for its exploration of cultural and language development, alongside several fictional naval and adventure timelines.

One preferred alternate-history scenario reverses the sequence of the invasions associated with the Norman Conquest. William lands first and loses to Harold Godwinson, who then loses to Harald Hardrada. Hardrada's victory establishes a Scandinavian political and cultural direction for England. In the imagined later history, England, Scotland and Wales belong to a Scandinavian sphere comparable to Iceland's place within it. The scenario uses language development, including a gendered Anglic language, while its historical basis is acknowledged to become less secure as it develops. Other suggestions include Clive Cussler's fictional history, a story that personifies Prince of Wales and Repulse after the loss of Force Z, and The Whale Has Wings.
