How Maps Lie: Propaganda Cartography from World War II
In 1942, Japanese-American illustrator Miki Hayakawa's contemporaries watched a very different kind of map spread across America: a 1942 U.S. propaganda map depicted Japan as a spider-like octopus, its ink-black tentacles reaching across the Pacific toward Australia and Hawaii. No coastline was distorted, no scale was technically wrong — yet the map was built entirely to make one nation look like a monster.
What You'll Learn
- How mapmakers use color, symbols, and projection choices to persuade rather than inform - Three specific propaganda techniques: monster metaphors, arrow maps, and selective scale - Real examples from World War I, World War II, and the Cold War - How to spot persuasive framing in a modern map or infographic
Technique 1: The Monster Metaphor
Cartoonist Fred W. Rose's 1877 map "Serio-Comic War Map" portrayed Russia as a giant octopus strangling Europe with its tentacles — a technique reused constantly in wartime propaganda. During WWII, both Allied and Axis mapmakers redrew enemy nations as octopuses, spiders, or snakes. The technique works because human brains process animal shapes emotionally before we consciously register the geography underneath.
Technique 2: The Arrow Map
After the fall of France in 1940, British newspapers ran maps with thick red arrows showing German troop movements as an overwhelming, unstoppable flood — even when the actual invading force was smaller than the arrows implied. Thick arrows compress complex troop logistics into a single visual impression of unstoppable momentum, making an army look larger and more threatening than official troop counts would suggest.
Technique 3: Selective Scale and the Mercator Panic
The standard Mercator projection (created in 1569 for sea navigation) massively inflates the size of land near the poles. Cold War-era U.S. maps exploited this: the Soviet Union, already the largest country on Earth, appeared even more enormous on Mercator maps than on equal-area projections, reinforcing the idea of an unstoppable Communist expansion. Greenland, for comparison, appears larger than Africa on a Mercator map — despite Africa being about 14 times bigger in real land area.
None of these maps contained factually false coordinates. The manipulation happens through choices that are technically legal on any map: what color to use for a country, whether to draw an arrow or a dotted line, and which map projection to pick. That's what makes propaganda cartography hard to spot.

Design Your Own Propaganda Map
Choose a fictional conflict between two made-up countries. Sketch a simple map using ONE technique from this lesson (monster metaphor, arrow map, or selective scale/color) to make one side look threatening or the other side look sympathetic. Below your map, write 3 sentences explaining exactly which persuasive choices you made and why they work. Deliverable: one sketched map plus a short technique explanation.
