International Boundaries of India – UPSC Indian Geography Notes
International Boundaries serve as the geographical borders of political or legal jurisdictions like countries, customs territories, and sovereign states. The creation of these International borders is known as boundary delimitation. In regions with free movement agreements, such as the European Union, international borders may be thinly guarded or completely open.
In contrast, borders like the India-Pakistan or North Korea-South Korea border can be heavily patrolled, with access controlled through designated crossings. Understanding international boundary lines is a significant aspect of the Geography Syllabus for the UPSC.
International Boundary Lines in the World
International boundaries, acting as geographical borders between political and legal jurisdictions like countries, customs territories, and sovereign states, are a crucial topic for UPSC aspirants studying the Geography Syllabus. This comprehensive guide seeks to furnish UPSC aspirants with a detailed understanding of international boundaries, their significance, and key boundary lines worldwide.
Understanding International Boundaries
International boundaries serve as the demarcations that separate two sovereign countries, establishing clear definitions for their territories and legal jurisdictions. The process of creating these borders is referred to as boundary delimitation.
While certain international borders, as seen within the European Union, may be thinly guarded or open, others, such as the India-Pakistan and North Korea-South Korea borders, are heavily patrolled with access strictly controlled through designated crossings.
International boundary lines represent the space between two sovereign countries, playing a crucial role in delineating territories and establishing the authority of a single national government within its borders. These boundaries not only help resolve land possession disputes but have, in some instances, been the cause of wars.

India’s Border Line Name List
India shares its international borders with seven neighboring countries, and among the numerous boundary lines, two of the most significant are the Radcliffe Line and the McMahon Line. These boundary lines carry particular importance for specific reasons, which are elaborated below for a deeper understanding.
Radcliffe Line – International Boundary between India and Pakistan
The Radcliffe Line, also recognized as the international boundary line between Pakistan and India, extends from Gujarat to the Jammu and Kashmir (J&K) border. Formed on August 17, 1947, it played a pivotal role in the partition of British India into three parts – India, West Pakistan, and East Pakistan (now present-day Bangladesh). The borderline between India and Pakistan further traverses the Jammu and Kashmir region, known there as the Line of Control (LOC).
McMahon Line – Boundary Line between India and China
The McMahon Line functions as the international boundary line between India and China, spanning from the eastern border of Bhutan to the Himalayas, extending until it reaches the great bend in the Brahmaputra River. Named after Sir Henry McMahon, the former foreign secretary of British India, this boundary line was established through a bilateral agreement signed between Tibet and Britain at a conference in Shimla on July 3, 1914. The McMahon Line spans approximately 890 km or 550 miles, signifying a significant border between India and China.
Line of Actual Control (LAC)
The Line of Actual Control (LAC) functions as the de facto borderline between India and China. Initially established as a ceasefire line, it later evolved into an informal boundary delineating the territories of China and India. The LAC is not precisely defined, contributing to occasional disputes and tensions between the two neighboring countries.
