Which Sikh guru was freed from imprisonment on Diwali?

Guru Hargobind was the Sikh guru freed from imprisonment on Diwali.

The sixth Sikh Guru, Guru Hargobind, was released from Gwalior Fort during the reign of Mughal emperor Jahangir. Sikh tradition connects his release with the liberation of 52 other detained rulers, which is why the associated celebration is called Bandi Chhor Divas, or the “Day of Liberation.”

The traditional account says Guru Hargobind agreed to leave only if the other prisoners could go free with him. A condition requiring the rulers to hold onto his robe is often described with the image of 52 ropes or tassels, though details of the story belong to Sikh religious tradition rather than a universally settled historical record.

Bandi Chhor Divas coincides with Diwali but has its own Sikh meaning. It celebrates freedom, justice and the protection of the oppressed. Guru Tegh Bahadur, Guru Gobind Singh and Guru Nanak were also major Sikh figures, but they are not the guru identified with this imprisonment-and-release story.
