In the concluding episode of the three-part series, Dr Thomas Asbridge reveals that the outcome of these epic holy wars was decided not on the hallowed ground of Jerusalem, but in Egypt. As trade blossomed between Christians and Muslims and the Mongol hordes arrived from Asia, a saintly French king - afire with crusading zeal - and the most remarkable Muslim leader of the Middle Ages fought for ultimate victory in the East. Drawing upon eyewitness chronicles and the latest archaeological evidence, Dr Asbridge argues that it was a fearsome slave-warrior from the Russian Steppes - now forgotten in the West - who finally sealed the fate of the crusades. And, most controversially of all, Asbridge challenges the popular misconception that the medieval crusades sparked a clash of civilisations between Islam and the West that continues to this day.

The $400 million cruise ship - which got off to a bad start when the champagne bottle failed to break on its launch - fell prey to the omens when it sank on Friday 13 January 2012 off the Italian coast. This programme pieces together the mistakes that led to the disaster. With a capacity of 3780 passengers and at an impressive 290m long and 31m high, the ship was a palace of the ocean. So how did this boat, hailed as a glorious example of modern technology, sink? And why do some critics say the design of these mega-cruisers is dangerous? These are just some of the questions this programme examines as it tries to understand how, after a century of safety measures and technological advances since the Titanic, a ship with so many passengers can sink. Using CGI and testimonial, it recreates a minute-by-minute account of the timeline to tragedy, featuring exclusive interviews with survivors, rescuers and world-renowned experts.
