The book "King John" by W. L. Warren was published in 1991 by Eyre & Spottiswoode in hardcover format. It falls under the topic of history and is an original work in English. The author delves into the historical subject of King John, providing readers with a detailed account of this particular period in history. This antiquarian and collectible book offers a valuable insight into the life and reign of King John.

First published in 1961, Warren was probably the first historian in recent times to assess the King objectively - ie with research based scepticism of the Victorian historians who wrote of John as the son of perdition. This is no apology for John, Warren gives us warts and all in a readable and balanced assessment.
