EKawaaz

During the times of Guru Amar Das the Nishan Sahib was white, to represent peace and simplicity. During the time of Guru Hargobind, however the Nishan Sahib mas made into a shade of yellow, known as Basanti, to show the spirituality of the Sikhs and their warrior spirit. After the creation of Khalsa, Guru Gobind Singh introduced Navy Blue (called Surmayee) flag, which is still the colour of the Nihang flags. The first Sikh flags were plain, but emblems were introduced by Guru Gobind Singh. The first Sikh emblem, was not the Khanda, but the three weapons, the Kattar (dagger), Dhal (shield) and Kirpan (sabre). Later these emblems were also used by the Sikh misls and the Empire. When Gulab Singh asked Maharaja Ranjit Singh to change the Nishan Sahib to saffron or deep orange Maharaja Ranjit Singh declined but later when he changed the army from traditional Akalis to French-style soldiers he made separate flags to respect Hindu and Muslim[1] ideologies. Later the Battle standards for Muslim regiments was the Lion and the Sun and the Hindu Regiments were various gods and goddesses.https://en.wikipedia.org/wiki/Nishan_Sahib Later during the British Rule it became from Basanti and Surmayee to Kesari and Surmayee due to the Hindu Mahants, Nirmalas and lack of historians. This influenced Sikhism a lot and it became the Kesri Nishan Sahib with a peacock feather on top. During the Singh Sabha Movement the Sikhs tried to restore Sikhism to its pristine glory so in the start it became the Flag of the Dal Khalsa but slowly it changed to the today's Nishan Sahib with the Khanda Emblem.
