International boundary lines are imaginary lines that separate one country from another. These lines are very important because they help define the area of each country and show where one nation ends and another begins. They are also important for understanding history, geography, and current world politics.
Some well-known boundary lines are the 38th Parallel, which divides North Korea and South Korea, and the 49th Parallel, which separates the USA and Canada. Another important line is the McMahon Line, which marks the border between India and China. These lines often carry great historical and political importance, as they represent agreements or conflicts between nations.
In India, the Radcliffe Line is a key boundary. It was drawn during the partition of India in 1947, separating India and Pakistan. Similarly, the Durand Line marks the border between Afghanistan and Pakistan.
Knowing about these boundaries is very useful for competitive exams. Questions about them often appear in general knowledge and geography sections. Understanding these lines helps students learn about international relations and the history of countries. This blog will list the most important international boundary lines that everyone should know, especially for exams like SSC, Railways, and other government job tests.
