The document discusses the rise and fall of European imperialism from 1800 to 1914. It explains that during this period, European control of global landmass expanded dramatically from 35% to 85%. The long legacy of European imperialism included establishing the foundations of modern global society through political, economic, social, and cultural influences around the world. The era also transformed European societies and politics. The document then analyzes the differences between "old" and "new" imperialism, noting that the latter period from 1830s to 1930s was driven by industrialization, new ideologies like nationalism and social Darwinism, and technologies like steamships that enabled further European expansion and dominance of other regions.
