Maps and Exploration
The German North Polar Expeditions were a short series of mid-19th century German expeditions to the Arctic. The aim was to explore the North Pole region and to brand the newly united, Prussian-led German Empire as a great power. In 1866, German geographer August Petermann wrote a pamphlet strongly advocating German participation in the international quest for the North Pole, which stimulated a German expedition.
