Over one billion Christians look to Rome, more than half of all Christians on the planet. But how did a small Jewish sect from the backwoods of 1st-century Palestine, which preached humility and the virtue of poverty, become the established religion of western Europe - wealthy, powerful and expecting unfailing obedience from the faithful? Amongst the surprising revelations, Professor MacCulloch tells how confession was invented by monks on a remote island off the coast of Ireland, and how the Crusades gave Britain the university system. Above all, it is a story of what can be achieved when you have friends in high places.

The series Warrior Graveyard uncovers some extraordinary warrior skeletons from history. Archaeologists and forensic scientists use remains to tell the story of famous warriors of the past and unleash the full force of modern forensics upon them: battle scars, bone deformations and recoverable scraps of DNA will all be tested and explored. CGI and drama will then bring them dramatically to life, revealing a revolutionary new picture of how these warriors lived - and died.
An archaeological and forensic examination of six crusaders' bones brings to life the 1179 Battle of Jacob's Ford, revealing the wounds that killed the warriors in the Holy Land. With every sword slash comes an insight into an historic day. Excavations along the Israel/ Jordan border are unearthing skeletons and rewriting the history of the First Crusade. The site at Jacob's Ford is the only known Crusader battle site with complete skeletons. To secure the road between Akkon and Damascus, King Baldwin IV of Jerusalem had a mighty castle built at the Jacob's Ford of the Jordan River in October 1178. The fortress was a thorn in the side of Sultan Saladin, so he had it stormed a year later, before it was completed.
Excavations have been taking place on the site of the legendary crusader castle since the early 1990s. Archaeologists and forensic experts have examined the remains of six fallen crusaders and uncovered fascinating details about the Battle of Chastellet. The programme has secured access to the excavation and remains of some of the 80 Crusader Knights and 750 foot soldiers stationed at the fort when it was attacked and its Crusaders massacred by Saladin's army in 1179, in the battle that changed the course of history in the Middle East.

Dr. Thomas Asbridge introduces the epic story of the Crusades – a tale of religious fanaticism and unspeakable brutality, of medieval knights and Jihadi warriors; of castles and kings; of heroism, betrayal, and sacrifice. He explains how, using fresh evidence, eye-witness testimonies and contemporary accounts – from both the Christian and Islamic worlds – we are able to re-examine this epic medieval drama, and how he has retraced the steps of the Crusaders from a small town in France to the magnificent cities of the Holy Land, bringing to life the human experience of the Crusades, and shedding new light on how it was that two of the world’s great religions waged war in the name of God.

In August of 2018, Greta Thunberg, a 15-year-old student in Sweden, starts a school strike for the climate. Her question for adults: if you don't care about her future on earth, why should she care about her future in school? Within months, her strike evolves into a global movement. Greta, a quiet Northern-European girl on the autism spectrum is now a world famous activist. The team behind Greta has been following the young activist from her very first day of school striking. The documentary shows the international crusade of Greta on in her goal to get people to listen to scientists about the world's environmental problems.

The most famous – and perhaps most misunderstood – episodes in the epic history of the Holy Wars that are known to history as The Crusades – the clash between Richard the Lionheart and Saladin. In July 1192, Richard the Lionheart stood poised for a strike on Jerusalem, while Saladin – mighty sultan of Islam – readied his troops inside the city, preparing for the inevitable attack. During a year-long campaign across Palestine, these two legendary leaders had fought each other to a stand-still. Thousands had perished, appalling atrocities had been perpetrated on both sides. And now they faced each other in a battle for their sacred objective.

Professor Robert Bartlett explores the impact of the Normans on southern Europe and the Middle East. The Normans spread south in the 11th century, winning control of southern Italy and the island of Sicily. There they created their most prosperous kingdom, where Christianity and Islam co-existed in relative harmony and mutual tolerance. It became a great centre of medieval culture and learning. But events in the Middle East provoked the more aggressive side of the Norman character. In 1095, the Normans enthusiastically answered the Pope's call for holy war against Islam and joined the first crusade. They lay siege to Jerusalem and eventually helped win back the holy city from the muslims. This bloody conquest left a deep rift between Christianity and Islam which is still being felt to this day.
