Russian Empire

By the end of the 19th century the size of the empire was about or almost 1/6 of the Earth's landmass; its only rival in size at the time was the British Empire. However, at this time, the majority of the population lived in European Russia. More than 100 different ethnic groups lived in the Russian Empire, with ethnic Russians composing about 45% of the population.
