Major Boundary Lines of India
Some of the major boundary lines of India are shown in the table below.
| Border Name | Description |
|---|---|
| Line of Control (LOC) |  The Line of Control (LOC) is the military-controlled border that separates India and Pakistan in the region of Jammu and Kashmir and Ladakh. Initially called the Ceasefire Line, it was renamed the Line of Control after the Shimla Agreement was signed in 1972. |
| Line of Actual Control (LAC) | The Line of Actual Control (LAC) is the border that divides India and China. Originally established as a ceasefire line, it was officially named the LAC after the 1962 India-China war. |
| Durand Line | The Durand Line is the boundary that separates British India (pre-1947) and Afghanistan. It was established in 1896 by Sir Mortimer Durand and historically marked the division between British India and Afghanistan. This line touches regions such as Pakistan-Occupied Ladakh and has remained a significant point of geopolitical tension, especially after the creation of Pakistan in 1947, as it now primarily separates Pakistan and Afghanistan. |
| Radcliffe Line | The Radcliffe Line is the boundary that divides India and Pakistan. It was named after Sir Cyril Radcliffe, the chairman of the Boundary Commission, and was established in August 1947. This line not only separates India and Pakistan on the western side but also divides India and Bangladesh on the eastern side. |
| McMahon Line | The McMahon Line is the international boundary between India and China. It was determined by Sir Henry McMahon, the foreign secretary of the British government, and was established during the Shimla Convention on July 3, 1914. |
