A great favorite of mine.
His “Modern Times” is still essential reading, to explain modern politics, sorting out the genealogy of current ideologies. Its a bit dated now, but nevertheless useful.
His histories are also probably the best short (or reasonably so given the subject) works available.
“A History of the Jews “
“A History of Christianity”
“A History of the American People”
And the wonderful “The Birth of the Modern”, on how the seeds of much of this modern world were sown in the Romantic movement of the 19th century.
I loved “Birth of the Modern.” I re-read it a year or two ago.
