Cities are growing at a faster rate than any other habitat on Earth. They may seem an unlikely place for animals to thrive, but they can be a world of surprising opportunity. Leopards prowl the streets of Mumbai, peregrine falcons hunt amongst New York's skyscrapers, and a million starlings perform spectacular aerial dances over Rome. In Jodhpur, langurs are revered as religious deities and in Harar, locals live in harmony with wild hyenas. Many animals, however, struggle to cope in the urban jungle. As the architects of this environment, can humans choose to build cities that are homes for both them and wildlife?

Nicholas felt enormous pressure to continue the dynasty and expand the empire. He saw his opportunity in the Far East. This brought him into conflict with a rising power, Japan. Russia's disastrous war against Japan prompts civil unrest. The birth of Prince Alexei is incredibly important. He's the long-awaited son that they had hoped so much for. But when Alexei is diagnosed with haemophilia, Siberian mystic Rasputin steps in. He's very good at realizing when something is open that will enable him to increase his power and wealth. The pressure of keeping the secret of Alexei's illness affects the political decisions that Nicky and Alix made for the rest of their reign.

The Romanovs retreat into a bubble of luxury while the czar's forces brutally suppress protests by a starving populace. Rasputin's influence grows, never mind the rumors and scandals. Many people believe Prime minister Peter Stolypin is the last hope of the Romanov Dynasty as reformer-in-chief. He is horrified by the rise of Rasputin. The fight between Stolypin and Rasputin is a battle for influence over Nicholas II. But Stolypin is shot in the Kiev Opera in 1911.

In 1914, Russia entered World War I in response to Austria-Hungary's declaration of war on Russia's ally Serbia. This was fought across multiple fronts while isolated from its allies. The Battle of Tannenberg, where the entire Russian Second Army was annihilated, cast an ominous shadow over the empire's future. The already-existing public distrust of the regime was deepened by the rising costs of the war and rumours of corruption. World War I takes Nicholas to the front. Back home, outrage grows over high casualties and Alexandra and Rasputin's political intrigues.

Rasputin is gone, but Nicholas II continues his catastrophic policies in war and at home. When Nicholas goes back to military headquarters, he is in fact leaving control of government, exactly when Russia needed to be held together by its Czar. The war by this time is deeply unpopular. It's not only unpopular, it's also arguably the engine that's causing enormous economic crisis, that's causing general unrest. Deprivation pushes the population from unrest to revolution.

Nicholas II abdicates, and civil war erupts. In May 1918, a year after the revolution, the Bolsheviks sent Anastasia, Alexei, Tatiana and Olga to join the rest of the family in Ekaterinburg. They're put in the Ipatiev mansion and It's given the name 'The House of Special Purpose.' As pro-royalist forces close in on the house where the Romanovs are imprisoned, the family's fate is sealed.
