International Boundary Lines
- International boundaries serve as geographical borders between political and legal jurisdictions such as countries, customs territories, and sovereign states.
- International boundaries are the demarcations that separate two sovereign countries, defining their territories and legal jurisdictions. The process of creating these borders is known as boundary delimitation.
- For example, the Line of Control (LoC) is the boundary line between India (Kashmir) and Pakistan.
- The Mason-Dixon Line is a boundary line between the 4 states of the United States of America.
- Some international borders such as those within a free movement area like the European Union are thinly guarded or completely open.
- Others such as the India-Pakistan border or the North Korea-South Korea border may be heavily patrolled with access controlled through designated crossings.

India’s Border Line Name List
India shares its international borders with seven neighbouring countries, and two of the most significant boundary lines are the Radcliffe Line and the McMahon Line.
Radcliffe Line
The Radcliffe Line, is the international boundary line between Pakistan and India.
It runs from Gujarat to the Jammu and Kashmir (J&K) border.
It was created on August 17, 1947, and 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 also passes through the Jammu and Kashmir region, where it is referred to as the Line of Control (LOC).
McMahon Line
The McMahon Line serves as the international boundary line between India and China, extending from the eastern border of Bhutan to the Himalayas 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 stretches approximately 890 km in length, marking a significant border between India and China.
Line of Actual Control (LAC)
The Line of Actual Control (LAC) acts as the de facto borderline between India and China.
Initially, it began as a ceasefire line, but it later evolved into an informal boundary separating the territories of China and India.
The LAC is not a precisely defined boundary, leading to occasional disputes and tensions between the two neighbouring countries.
