aka Nankana forms a very important..
Saka Nankana forms a very important part of Sikh history. The saka constitutes the core of the Gurdwara Reform Movement started by the Sikhs in early twentieth century. The interesting part of this saka is the unprecedented discipline, self-control and exemplary patience displayed by the peaceful Sikh protesters even in the face of extreme barbarism. Even the national leaders like Mahatama Gandhi had to acknowledge in no ambiguous terms the glory and the prestige which the peaceful and passive resistance of the Sikhs had brought to the India's Struggle for freedom.

Historical Background
The concepts of Sangat, Pangat, Dharamshala (Gurdwara) and Kirtan took firm roots during this period and became important constituents of Sikhism. Congregations in Gurdwaras had played crucial roles in the religious and social affairs of the early Sikhs. Later, they assumed wider dimensions by transforming into religio-political organisation. The peaceful and non-political budding Sikh brotherhood was transformed into a proud and fiercely martial nation through the baptismic process of Amrit-pan. After a long and continuous resistance of several decades against the tyrannies of Mughal rule, the brave Sikhs finally emerged victorious and succeeded in carving out 12 Khalsa principalities in Punjab which soon led to the creation of a unified Khalsa kingdom with Ranjit Singh at the helms. Maharaja Ranjit Singh reconstructed the Gurdwaras earlier destroyed by the Moghuls and also raised many new ones at the sacred places connected with the Sikh Gurus. For the sustenance of the Mahants, Maharaja Ranjit Singh had attached handsome landed properties with many of these Gurdwaras. The earlier Mahants were devoted Sikhs and true missionaries who did a lot for the spread of Sikhism. As the times rolled by, the Gurdwara incomes swelled enormously and the enormous money corrupted and degenerated the later-time Mahants into loose lived individuals. They started treating the Gurdwara properties as if they were their personal fiefs. This changed the things for Sikh Panth.
