Previously on the first season on ‘Rise of Empires: Ottoman,’ Sultan Mehmed II won the battle for the conquest of the great city of Constantinople. Eight years after, Mehmed enjoys the might of his rule over the Ottoman Empire and holds the most significant reputation around his name in the world around. His eyes now glare at the west, with ambitions to seize control over all of Europe. However, there’s a lint in his eyes in the form of Vlad Dracula, the Voivode of Wallachia — a vassal state under the Ottoman Empire. The second season retells the Mehmed vs. Vlad throw down where the two historical figures lay it all out against each other in a fierce battle for the ages.
In the first episode, Vlad along with his brother Radu were left with Mehmed I by their father, as a guarantee that he would not betray the Sultan and help the Hungarians — something he was strongly suspected of. Over time, Vlad went on to get coronated for the throne of Wallachia and his characteristic hotheadedness and arrogance, as well as resentment against the Sultan and the empire, drove him to be unruly. As the threat of his rebellion became the largest it had ever been, Mehmet prepares for battle and moved with his mighty war machine of an army to defeat him.

Hours before Mehmed II launches his final assault, an ominous sight shakes both sides. Rumors of a 40-ship fleet's imminent arrival have swirled for weeks, but it's exact whereabouts remained unknown. Ottoman cannons reduced the city walls to rubble, and Venetian reinforcements arrived too late. The conquest of Constantinople ushers in a new era for the Ottoman Empire, being a dominant force in world politics for 300 years. Mehmed II, in many senses, changed the nature of world history.

The Bronze Age had the first large urban centers, powerful kingdoms and armies, writing, and trade routes across vast areas. What led to the collapse of the city-state entities and the end of the Bronze Age? Possibly a perfect storm of uncontrollable factors that are still being researched.

Between the 1920s and the 1960s the world's great powers sent vast military-style expeditions to conquer the peaks of the Himalayas, with Everest at their head. This was a great game played - camera in hand - by Imperial Britain, Nazi Germany and superpower America. As a result, Himalayan mountaineering's most iconic, epic and tragic moments didn't just go down in history, but were caught on film - from the deaths of Mallory and Irvine on Everest in 1924, to Everest's final conquest in 1953 by Hillary and Tensing. Using footage never before seen on British television, this is the story how of how film-makers turned the great peaks into great propaganda.

David Attenborough embarks on an extraordinary journey to unravel one of nature s most gripping stories the evolution of flying animals. The power of flight is one of the greatest miracles of nature. Over one hundred billion creatures soar through the air today - from nectar-drinking hummingbirds, to armoured airborne beetles; from bats hunting in the black of night, to bizarre winged lizards. The film travels back in time to unravel the astonishing 300-million-year story of how these animals first appeared, and then evolved into the huge variety of aeronauts that fill our skies today. Only now, using the latest scientific analysis, can he reveal the hidden mechanics behind their gravity-defying skills. Ground-breaking 3D cameras, high speed filming and stunning CGI bring the viewer closer than ever to this astounding aerial world.

David Attenborough continues his search for the origins of flying animals, as he charts the rise of new, larger creatures – extinct reptiles that flew on wings of skin, dinosaurs that sprouted feathers to become the ancestors of birds, and gliding mammals that emerged from a life in the trees to dominate the night as bats. His journey spans the globe – from the rainforests of Borneo to see bizarre gliding animals, to China and its new discoveries of dinosaur fossils. Stunning CGI brings to life creatures that disappeared over 200 million years ago, and new filming techniques bring us closer than ever to the secrets of flight itself.
