I found that Alec Ryrie, author of Protestants a book I’m reading has a blog.
One of the posts deals with preparations for the publication of Protestants for UK, US and Dutch editions.
From Ryrie:
“In secular old Britain, this is being marketed as a history book; in America, more more as a religious one.
[a] sign of this difference is the slightly different subtitles: America gets Protestants: The Faith That Made the Modern World whereas Britain has Protestants: The Radicals Who Made the Modern World.”
