Chipko movement was started bybishnoi samaj of rajasthan

The first ever Chipko Movement was initiated by the Bishnoi Samaj in Rajasthan about 260 years ago.

Explanation:

It all began when the Jodhpur King ordered to axe a huge number of trees in the khejadi village of Jodhpur.

When the soldiers began to cut the trees in spite of people protesting against it, one of the villagers (Bishnoi community) named, Amrita Devi, hugged a tree along with her daughters so as to protect it from the soldiers.

But unfortunately, the soldiers sacked the heads of Amrita Devi and her daughters; which led the villagers to rise together and protect the trees in the same way like how Amrita did.

The soldiers also sacked a lot of villagers who embraced the trees. Finally, the king startled at the unity of the people, abandoned the idea of axing the trees.

This movement based on the principles of satyagraha and non-violent resistance done by hugging the trees to protect them from being axed down became the novel example for all forest conservation movements.
