For Sikhs, in addition to its significance as the harvest festival, during which Sikhs hold kirtans, visit local gurdwaras, community fairs, hold nagar kirtan processions, raise the Nishan Sahib flag, and gather to socialize and share festive foods, Vaisakhi observes major events in the history of Sikhism and the Indian subcontinent that happened in the Punjab region. Vaisakhi as a major Sikh festival marks the birth of the Khalsa order by Guru Gobind Singh, the tenth Guru of Sikhism, on 13 April 1699. Later, Ranjit Singh was proclaimed as Maharaja of the Sikh Empire on 12 April 1801 (to coincide with Vaisakhi), creating a unified political state.
Vaisakhi was also the day when Bengal Army officer Reginald Dyer orders his troops to shoot into a protesting crowd, an event which would come to be known the Jallianwala Bagh massacre; the massacre proved influential to the history of the Indian independence movement.
This holiday is observed by Hindus and is known by various regional names in other parts of India. For many Hindu communities, the festival is an occasion to ritually bathe in sacred rivers such as Ganges, Jhelum, and Kaveri, visit temples, meet friends, take part in other festivities, and perform a mandatory daan (charity) especially of hand fans, water pitchers and seasonal fruits. Community fairs are held at Hindu pilgrimage sites. In many areas, processions of temple deities are taken out. Although Vaisakhi began as a grain harvest festival for Hindus it eventually gained historical association with the Sikhs.
