The book series does not happen in one particular timeframe. Instead, it is set in many different times in the history of the world of Redwall. Some of the books focus on characters who, in another book, are historical figures (e.g., Martin the Warrior's father, Luke, in "The Legend of Luke"). Usually, those books are set before Redwall Abbey was started. There is a timeline in the Redwall series, but it often places the books in a completely different order than the order they were written. However, there were two times when the novels were published in chronological order.
