Countries & Borders

The world is divided into approximately 195 recognised sovereign countries, each with defined borders that have been shaped by history, war, diplomacy, and geography. Some borders follow natural features like rivers and mountain ranges; others were drawn artificially during colonial periods. Countries vary enormously in size - from Russia, the world's largest nation by area, to Vatican City, the smallest. Border regions are often culturally rich and politically complex. This sub-category tests knowledge of which countries border each other, how national boundaries have changed over time, which nations share land borders, and the geopolitical significance of key borders and boundary disputes across the world.
