It is believed that the fort Kalai-Vamar was built by local people in defence of the Chinese advancement to Pamirs. Many times Kalai-Vamar fell to Shahs of Darwaz and Shughnan remaining under control of Shughnan until Afghans of Badakhshan took it on the last quarter of 19th century. In 1885 Russians liberated Pamiri kingdoms of Panj right bank but soon gave them to Manghit Emirate of Bukhara where they resided until the October Revolution. During Soviet Era the Castle of Vamar was destroyed and its territory mainly demolished giving way to military base facilities.

On the morning of May 18, 2022, Rushon was the scene of a violent crackdown on protesters by security forces with several casualties. Local residents had been blocking the road to Khorugh, where protests against human rights violations were ongoing, in order to prevent a military convoy from passing.
