The Khalistan movement is a separatist movement seeking to create a homeland for Sikhs by establishing an ethno‐religious sovereign state called Khalistan in the Punjab region. The proposed boundaries of Khalistan vary between different groups; some suggest the entirety of the Sikh-majority Indian state of Punjab, while larger claims include Pakistani Punjab and other parts of North India such as Chandigarh, Haryana, and Himachal Pradesh. Shimla and Lahore have been proposed as the capital of Khalistan.

Separatism is the advocacy of cultural, ethnic, tribal, religious, racial, governmental, or gender separation from the larger group. As with secession, separatism conventionally refers to full political separation. Groups simply seeking greater autonomy are usually not considered separatists. Some discourse settings equate separatism with religious segregation, racial segregation, or sex segregation, while other discourse settings take the broader view that separation by choice may serve useful purposes and is not the same as government-enforced segregation. There is some academic debate about this definition, and in particular how it relates to secessionism, as has been discussed online.
