Geopolitics & Borders
📋 What it is
Borders are agreed lines dividing land into countries; some follow rivers or mountains, others are straight human-drawn lines.
🗣️ Coach says
A border is a decision, not a natural fact. Some follow rivers or mountain ranges; many are ruler-straight lines someone drew on a map. Knowing why a border sits where it does explains a lot of the world’s cooperation — and its conflicts.
🧠 Memory hook
Borders are DECISIONS. Some follow nature, some are drawn straight.

Reading a border’s origin reveals the history and tension behind a map.
