Book cover of The Northern Crusades

Jon Byrne Author Of Sword Brethren

From my list on Medieval Crusades.

Why am I passionate about this?

I have always been passionate about history–especially military history, and have collected books since I was a child. In time, I became particularly absorbed with the medieval world, building up a comprehensive library of books on all aspects of life during this fascinating time. In my research, I have traveled to all of the locations mentioned in the book: East Anglia, Bremen, Lübeck, and Latvia. I particularly love trying to bring the characters to life, fitting them, and creating an interesting plot around actual historical events.

Jon's book list on Medieval Crusades

Jon Byrne Why Jon loves this book

I have always been fascinated by medieval history, but I became interested in this particular era after reading this book and learning about the German Order of Swordbrothers (Schwertbrüderorden). 

What intrigued me was that they were a small Order, not very pious or saintly. They were unorthodox and argued constantly with Bishop Albert, the leader of the Christian mission. They were a rough and ready lot, acting more like brigands than warrior monks. One of the brothers murdered the first master, and they locked up their second master when he tried to exert more control over their behavior. Over time, they were accused of almost every crime.

I loved Christiansen’s book, which opened a new world of discovery. He writes in a witty, easy-to-read style that hooked me from the beginning.

What is this book about?

The 'Northern Crusades', inspired by the Pope's call for a Holy War, are less celebrated than those in the Middle East, but they were also more successful: vast new territories became and remain Christian, such as Finland, Estonia and Prussia. Newly revised in the light of the recent developments in Baltic and Northern medieval research, this authoritative overview provides a balanced and compelling account of a tumultuous era.

Jon's book list on Medieval Crusades

Jon Byrne Why Jon loves this book

This is an action-packed book that tells the story of Ferdia, an Irish noble, who is held as a hostage in Wales to ensure the good behavior of his father. He faces relentless bullying and persecution before saving the life of King Richard III and entering his court, where he becomes the king’s squire. The action continues in France as Richard attempts to put down a rebellion, but the larger threat to Ferdia himself turns out to be a member of King Richard’s own family.

The book has all the ingredients of an epic historical adventure, with thrilling action, relentless battles, and intrigue. I particularly enjoyed Kane’s vivid description of the 12th-century world and the authentic period details. The series continues with Crusader and King.

Jon Byrne Why Jon loves this book

I first read this book over thirty years ago and it is set during the Albigensian Crusade against the Cathars in Southern France. There is a major love and romance element to the plot that sees Roland, a troubadour, pitted against his half-brother Amalric.

I bought the book second-hand and have read it a few times over the years. Beforehand, I knew very little about the brutal Inquisition and the Albigensian Crusade in particular, and this book ignited my interest in a period not often covered in historical fiction. I would recommend it to anyone interested in this little-known period of history.

William Urban is an American history professor who specializes in the Baltic Crusades. He is probably the pre-eminent English-speaking historian on this subject and has written many other books–mostly on this theme or the Teutonic Knights. I particularly enjoy his no-nonsense writing style. The book has proven invaluable in my own research as it just concentrates on the Crusade in Livonia and Estonia in the first half of the 13th century–as well as showing the other political events taking place in Germany at the time. 

Urban was a great help to my own book. He kindly read an earlier draft of Sword Brethren and gave me some crucial historical advice. He has also agreed to read the next book in the series early in 2025, and I await his opinion with anticipation.

Book cover of Pagan's Crusade

Wendy Orr Author Of Cuckoo's Flight

From my list on to bring history to life.

Why am I passionate about this?

I’ve always been fascinated by history, and when I dreamed of being an author, imagined I’d write historical fiction. However, it took many writing detours to arrive there. (Nim’s Island, by the way, has no basis in historical fact!). When I first imagined the story that led to the Minoan Wings trilogy, I fell in love with researching this era, which is particularly intriguing because there are virtually no written records. Visiting the ruins of a four-thousand-year-old town on Crete under the guidance of an archaeologist who had not only excavated there but had become passionately involved with my imaginary characters, was an absolute highlight of my life.

I fell in love with the irrepressible Pagan as soon as I read this book. It’s difficult to imagine that life with the Knights Templar at the time of the Crusades was highly amusing – but despite the wealth of knowledge and detail that informs this book, it is wry and sometimes laugh-out-loud funny. Who wouldn’t love Pagan’s favorite curse: "Christ in a cream cheese sauce’?"

Book cover of The Templars

Helena P. Schrader Author Of The Tale of the English Templar

From my list on understanding the Knights Templar.

Why am I passionate about this?

I became fascinated by history when, as a child, I visited the Coliseum in Rome; my father told me, “This is where they fed the Christians to the lions.” That awakened my curiosity for people of the past, and I went on to earn an undergraduate degree and a PhD in history at the Universities of Michigan and Hamburg respectively. My interest in the crusades was ignited by the enormous disconnect between popular perceptions and historical reality, and I have published two nonfiction books on the Crusader States, as well as seven novels set in the era of the crusades. The Knights Templar were an important component of my research.

Regina Pernoud is one of my favorite scholars on the Middle Ages generally. Her books, Those Terrible Middle Ages: Debunking the Myths, and Women in the Days of the Cathedrals, are witty and well-aimed attacks against ignorance and prejudice.

In this book on the Knights Templar, she takes on with verve the many myths and misconceptions about the Templars. I particularly loved her analysis of Templar architecture, which starts with looking at the more than 9,000 Templar commanderies across Western Europe and their humble agricultural character.

Her chapter on the Templars’ banking activities is really more a dissection of the myth about Templar wealth and is completely compelling. All in all, this is a book that brings you back to reality and away from the silly conspiracy theories that still dominate so much literature about the Templars.

What is this book about?

For centuries, historians and novelists have portrayed the Knights Templar as avaricious and power-hungry villains. Who were these medieval monastic knights, whose exploits were the stuff of legend even in their own day? Were these elite crusaders corrupted by their conquests, which amassed them such power and wealth as to become the envy of kings?

Indignant at the discrepancies between the fantasies, on which "writers on history of every kind and hue have indulged themselves without restraint", and the available evidence, RTgine Pernoud draws a different portrait of these Christian warriors. From their origins as defenders of pilgrims to the…

Book cover of The Rule of the Templars: The French Text of the Rule of the Order of the Knights Templar

Helen Nicholson Author Of A Brief History of the Knights Templar

From my list on the real history of the Knights Templar.

Why am I passionate about this?

As my father was a keen amateur historian, family holidays always involved visits to medieval castles, abbeys, and Roman antiquities, but it wasn’t until I’d finished a University history degree and started training as an accountant that I encountered the Templars. Reading a primary source from the Third Crusade, I found the medieval author praised the Templars – yet few modern histories mentioned them, or, if they did mention the Templars, they claimed they were unpopular. My curiosity led me to undertake a PhD on medieval attitudes towards the Templars, Hospitallers, and Teutonic Knights, and eventually to a university post and a professional career in medieval history, writing history books focused on primary sources.

Helen Nicholson Why Helen loves this book

The obvious best guide to the historical Templars is the regulations that they produced for their own use. This book is a reliable English translation of those regulations.

Of course these regulations only tell us what the leaders of the Order of the Temple believed that the brothers should be doing, not necessarily what they actually did do, day by day – but they give us an insight into the brothers’ ideals and what their purpose.

The regulations also include many examples of when things didn’t go as planned and what the brothers did about it, allowing us a glimpse of the problems and challenges the brothers encountered defending the crusader states.

Both monastic rule and military manual, the Rule is a unique document and an important historical source.

The Order of the Knights Templar, whose original purpose was to protect pilgrims to the Holy Land, was first given its own Rule in 1129, formalising the exceptional combination of soldier and monk. This translation of Henri de Curzon's 1886 edition of the French Rule is derived from the three extant medieval manuscripts. Both monastic rule and military manual, the Rule is a unique document and an important historical source. It comprises thePrimitive Rule, Hierarchical Statutes, Penances, Conventual Life, the Holding of Ordinary…

Historical accuracy is important to me. I am not interested in fantasy or alternative history, so when I read about any topic, whether in fictional or nonfictional form, I want books based on the historical record. Malcolm Barber is one of the leading scholars on the Knights Templar of the last three decades.

This book is a concise summary of his scholarship and is for me the absolute bible on the history of the Knights Templar.

By Malcolm Barber ,

2 authors picked The New Knighthood as one of their favorite books, and they share why you should read it.

What is this book about?

The Order of the Temple, founded in 1119 to protect pilgrims around Jerusalem, developed into one of the most influential corporations in the medieval world. It has retained its hold on the modern imagination thanks to the dramatic events of the Templars' trial and abolition two hundred years later, and has been invoked in historical mysteries from Masonic conspiracy to the survival of the Turin shroud. Malcolm Barber's lucid narrative separates myth from history in this full and detailed account of the Order, from its origins, flourishing and suppression to the Templars' historic afterlife.

A picture is worth a thousand words! History books are filled with text and lots of footnotes and bibliographies, but so much of what is written can be boiled down or better explained by good pictures. And that’s what Nicholson has done in this book.

To supplement her concise and factual text (she’s a leading scholar on the topic of the Military Orders), she’s collected hundreds of images that illustrate the Templars—their castles and manors, their churches, their seals. She also provides colorful depictions of them from medieval sources, both frescoes and illuminated manuscripts. This book evokes the Templars and their lifestyle in a way that other books don’t even try. I love it!

Much has been written about the Knights Templar in recent years, most of it highly speculative and with no historical foundation. They have been associated with everything from Freemasonry to the Holy Grail, the pyramids, the Shroud of Turin and space travel. A leading specialist in the history of this legendary medieval order now writes a full account of the knights of the Order of the Temple of Solomon, to give them their full title, bringing the latest findings to a general audience. There is no other accurate popular history of the Templars currently available aimed at a general audience.…

Life is taking a bite of the comedy/tragedy sandwich, savoring the mix of flavors, deciding how you feel about the taste, and taking another bite. I love writing that can gather experiences from across the emotional spectrum and incorporate them into a narrative that is absurd and all the more true because of it. These five books do it better than the rest.

Patrick Canning Why Patrick loves this book

Overstuffed and labyrinthine, Eco’s novel dives into a highly academic rabbit hole of conspiracy theories that toss me head over heels like a strong wave in the ocean. It reads a bit like The DaVinci Code written by Thomas Pynchon (who we’ll get to in a minute), the paranoias stemming from historical entities like the Knights Templar and the Rosicrucians.

I’d be hard-pressed to provide an accurate summary of events, but it all makes for a pleasantly bewildering reading experience.
