Alan Palmer was Head of the History Department at Highgate School from 1953 to 1969, when he gave up his post to concentrate on historical writing and research.
A very good and readable biography but I read this before I went to university in 1976 - a lot has happened since then most notably the recent book 'Alexander I : The Tsar Who Defeated Napoleon' by Marie-Pierre Rey (2012 - see a very good review at: https://www.jstor.org/stable/10.5612/... no paywall) but in many other fine books such as Adam Zamoyski's 2005 '1812 Napoleon's Fatal March on Mosow'. The days when even the work of excellent amateur historians like A.W. Palmer could be treated seriously is long gone. It is very readable but it is fifty years old.
This was a great read, that I read back years ago. It was the first book to introduce me to the Romanovs. Alexander I was an interesting character and one of the last of the ‘great’ Tsars of Russia. He had his flaws but as this book shows, he was crafty when it counted.
