Nischal ( Punjabi:, Hindī: ), originally Nichal is a Hindu Punjabi Rajput surname originating in the Punjab region of the Indian subcontinent. It is part of the broad Kshatriya varna ( caste). They are traditionally members of the military or ran in an administrative capacity. The Kshatriya were assigned to protecting the Hindu dharma. Over the course of time, Nischals migrated to places across Punjab from their original homeland in Ajmer-Merwara and Rajputana.
Nischals came to be known as Mair Rajputs from within amongst the Punjabi Hindu Bhati Rajputs and originate from the Rajput clans of Rajasthan in Ajmer and migrated to the Punjab later in their history.
When the Muslim country of Pakistan was created in 1947 with the partition of India, most of the Nischals living in West Punjab migrated to India. Several Nischal families before having to migrate to India after Indian Partition can trace their origins to Adamke Village, which is located in Daska Tehsil of Sialkot District in West Punjab, which was in former Undivided India but now in Pakistan.
Today, Nischals live in numerous regions within India, but are mostly concentrated in Punjab, Haryana, Delhi, Uttar Pradesh. Nischals are usually Hindu Rajputs but some may be also Sikh, as the religions are generally very close in the Punjab region.
Nischals are Bhati ( Yaduvanshi) Rajputs who originate from Jaisalmer area of Rajputana, when Bhatis migrated to Punjab region centuries ago, the local Punjabi people started calling them Bhatti Rajputs in local Punjabi language as Bhati is pronounced as Bhatti in Punjabi.
