What subjects and regions were emphasized in Leopold von Ranke’s nine-volume world history?

Leopold von Ranke’s nine-volume world history, published between 1881 and 1888, serves as a broad account of the evolution of culture from the ancient Greeks through the 15th century.1

Regarding the subjects and regions emphasized in this work:

• Regional Focus: The history is primarily a history of Europe, focusing on the development of Latin and Germanic nations. The non-European world is addressed only marginally.1
• Thematic Focus: Rather than being a work of critical research or philosophical speculation, it emphasizes the evolution of culture. Consistent with Ranke’s broader historiographical approach, the work centers on political history, specifically the foreign relations of states and their systems of government and administration.1
• Conceptual Framework: Ranke viewed history as a complex process of "historical life" that takes its most effective form within the great states. He wrote the work with the conviction that the peaceful evolution of culture was protected against revolution and that the conflict between popular sovereignty and the monarchy had been settled in favor of the latter.1
