Khalsa in the context of "Guru Gobind Singh"

The Sikh Khalsa Army (Punjabi: ਸਿੱਖ ਖ਼ਾਲਸਾ ਫੌਜ, romanized: Sikha khālasā phauja), also known as Khalsaji, or simply Sikh Army, was the military force of the Sikh Empire. With its roots in the Khalsa founded by Guru Gobind Singh, the army was later modernised on Franco-British principles by Maharaja Ranjit Singh. It was divided in three wings: the Fauj-i-Khas (elites), Fauj-i-Ain (regular force) and Fauj-i-Be Qawaid (irregulars). Due to the lifelong efforts of the Maharaja and his European officers, it gradually became a prominent fighting force of Asia. Ranjit Singh changed and improved the training and organisation of his army. He reorganized responsibility and set performance standards in logistical efficiency in troop deployment, manoeuvre, and marksmanship. He reformed the staffing to emphasize steady fire over cavalry and guerrilla warfare, improved the equipment and methods of war. The military system of Ranjit Singh combined the best of both old and new ideas. He strengthened the infantry and the artillery. He paid the members of the standing army from treasury, instead of the Mughal method of paying an army with local feudal levies.

The Bhangi Misl (Punjabi pronunciation: [pə̃˨ŋɡiː mɪsəl]) was a large and powerful Sikh Misl headquartered in Amritsar. It was founded in the early 18th century by Sardar Chhajja Singh Dhillon, who was baptised into the Khalsa tradition by Banda Singh Bahadur. It was a first misl to established a Khalsa Raj and publish Khalsa currency coins. The Bhangi Kingdom/Misl was founded by Dhillon Jats.

Sikh sects, denominations, traditions, movements, sub-traditions, also known as sampardai (Gurmukhi: ਸੰਪਰਦਾ; saparadā) in the Punjabi language, are sub-traditions within Sikhism with different approaches to practicing the religion. Sampradas believe in one God, typically rejecting both idol worship and castes. Different interpretations have emerged over time, some of which have a living teacher as the leader. The major traditions in Sikhism, says Harjot Oberoi, have included Udasi, Nirmala, Nanakpanthi, Khalsa, Sahajdhari, Namdhari (Kuka), Nirankari, and Sarvaria.

During the persecution of Sikhs by Mughals, several splinter groups emerged, such as the Minas and Ramraiyas, during the period between the death of Guru Har Krishan and the establishment of Guru Tegh Bahadur as the ninth Sikh Guru. These sects have had considerable differences. Some of these sects were financially and administratively supported by the Mughal Empire in the hopes of gaining a more favorable and compliant citizenry.

Guru Nanak founded the Sikh religion in the Punjab region of the northern part of the Indian subcontinent in the 15th century and opposed many traditional practices like fasting, Upanayana, idolatry, caste system, ascetism, azan, economic materialism, and gender discrimination.

Guru Gobind Singh, tenth of the ten Sikh Gurus, founded the Khalsa panth in the Punjab region of the northern part of the Indian subcontinent in the end of seventeenth century. He baptised five Sikh people from different parts of India, with different social backgrounds, to form the Khalsa. Those five Beloved Ones, the Pañj Piārē, then baptised him into the Khalsa fold. This gives the order of Khalsa a history of around 500 years. Historical theory and analysis suggests that Sikhism came into existence during the early medieval period of the Bhakti movement and also after repeated invasions by Muslim rulers upon the Hindu community during Mughal rule, which lasted between (1526–1857 AD) especially in the region of North India.

The kirpan (Punjabi: ਕਿਰਪਾਨ; pronunciation: [kɪɾpaːn]) is a blade that Khalsa Sikhs are required to wear as part of their religious uniform, as prescribed by the Sikh Code of Conduct. Traditionally, the kirpan was a full-sized talwar at around 76 cm (30 inches) long; however, British colonial policies and laws introduced in the 19th century reduced the length of the blade, and in the modern day, the kirpan is typically a dagger between 5 to 12 inches. According to the Sikh Code of Conduct, "The length of the sword to be worn is not prescribed", but must be curved and single edged (as its original sword form was). It is part of a religious commandment given by Guru Gobind Singh in 1699, founding the Khalsa order and introducing the five articles of faith (the five Ks) which must be worn at all times. A kirpan is held in a holster known as a gatra, which is worn over the right shoulder and across the body.

In Sikhism, the Five Ks (Punjabi: ਪੰਜ ਕਕਾਰ, Pañj Kakār, Punjabi pronunciation: [ˈpənd͡ʒ.ˈkəˌka:ɾ]) are five items that Guru Gobind Singh, in 1699, commanded Khalsa Sikhs to wear at all times. They are: kesh (ਕੇਸ਼, keś, unshorn hair and beard since the Sikh decided to keep it), kangha (ਕੰਘਾ, kãṅghā, a comb for the kesh, usually wood), kara (ਕੜਾ, kaṛā, a bracelet, usually made of iron or steel), kachhera (ਕਛੈਰਾ, kachairā, an undergarment), and kirpan (ਕਿਰਪਾਨ, kirpān, a small curved sword or knife made of iron or steel).

The Five Ks are not just symbols, but articles of faith that collectively form the external identity and the Khalsa devotee's commitment to the Sikh rehni, 'Sikh way of life'. A Sikh who has taken Amrit and keeps all five Ks is known as Khalsa ('pure') or Amritdhari Sikh ('Amrit Sanskar participant'), a Sikh who has not taken Amrit but follows the teachings of the Sri Guru Granth Sahib is called a Sahajdhari Sikh.

Guru Hargobind (Gurmukhi: ਗੁਰੂ ਹਰਿਗੋਬਿੰਦ, pronunciation: [gʊɾuː ɦəɾᵊgoːbɪn̯d̯ᵊ]l 19 June 1595 – 28 February 1644) was the sixth of ten Gurus of the Sikh religion. He had become Guru at the young age of eleven, after the execution of his father, Guru Arjan, by the Mughal emperor Jahangir.

Guru Hargobind introduced the process of militarization to Sikhism, likely as a response to his father's execution and to protect the Sikh community. He symbolized it by wearing two swords, representing the dual concept of mīrī and pīrī (temporal power and spiritual authority). In front of the Harmandir Sahib in Amritsar, Hargobind constructed the Akal Takht (the throne of the timeless one). The Akal Takht represents the highest seat of earthly authority of the Khalsa (the collective body of the Sikhs) today.
