Which Sikh city was founded by Guru Ram Das as Ramdaspur?

The Sikh city founded by Guru Ram Das as Ramdaspur is Amritsar.

Guru Ram Das, the fourth Sikh Guru, established the settlement around a sacred pool in the late sixteenth century. The town was initially known as Ramdaspur, meaning the town of Ram Das, and later became known as Amritsar, a name associated with the pool of nectar or immortality.

Guru Arjan developed the central shrine in the pool, eventually known as the Harmandir Sahib. The growing settlement became a major centre of Sikh worship, trade, learning, and community life. Its history is therefore broader than the Golden Temple alone.

Amritsar is sometimes mistaken for Anandpur Sahib, which was founded by Guru Tegh Bahadur and became closely associated with Guru Gobind Singh and the Khalsa. It is also distinct from Lahore, an important historic city in the wider Punjab region.
