I recently read a majority of this book while researching the cross-cultural influence of the British Empire and its subject lands and peoples for a paper I wrote on David Lean's Lawrence of Arabia and his adaptation of EM Forster's A Passage to India . The British Imperial Century was written very understandably, in straightforward language, and relays the author's message clearly. Parsons reports that the Empire was very mutable and carried the culture of its subjected peoples to all corners of the world, as it is said, "The sun never sets on the British Empire." Readers will learn such ideas, like how Indian culture, from foods and words, to spiritual beliefs and architecture traveled the world due the colonization of many areas of the world by the British.
If you're interested in world history, especially during the age of imperialism, I highly recommend Parson's book.
