On 24 February 1848, King Louis Philippe I abdicated in favor of his nine-year-old grandson, Louis Philippe, Comte de Paris, author of that book. Louis Philippe I lived out the last two years of his life in England before dying in 1850. Alexandre Dumas (1802-1870) was one of the most famous and prolific authors of all time. He is best known in the English speaking world for "The Three Musketeers," "The Count of Monte Cristo," and "The Man in the Iron Mask." However, he wrote dozens of other works. Dumas had every reason to write this book, as he personally knew and supported Louis Philippe, King of the French.
