In 1738, Budha Dal and Taruna Dal come in existence.
Budda Dal, famously known as Panjva Takhat, Chalda Vaheer, Chakravarti or Shiromani Panth Akali Budha Dal, is head section of Nihang Sikhs, which look into affairs of Khalsa Panth and one of the oldest military regiment of Sikhs. Budhadal is 5th and the final takhat.
Kapur Singh, finding it difficult to manage such a large force centrally, particularly after Darbara Singh's death in 1734, divided the camp into two parts on the basis of age of the Jathedars or group leaders. The elders camp comprising jathas of older leaders such as Sham Singh, Gurbakhsh Singh, Bagh Singh, Gurdial Singh, Sukkha Singh and Kapur Singh which is Buddha (elder) Dal.
The groups of younger Sikhs were called the Taruna (youthful) Dal. The latter was further subdivided into five jathas, each with its own drum and banner. The Buddha Dal too was similarly subdivided after some time. Nawab Kapur Singh remained in overall command of the two Dals which jointly were called the Dal Khalsa. Men were free to join jathas of their choice.
