The term Siddis (also called Habshi) refers to a Negroid people in India.
They are the descendants of slaves first brought to parts of Pakistan and India by Arab merchants in medieval times from the Bantu-speaking parts of eastern Africa.
In Western India (today's Indian states of Gujarat and Maharashtra), the Siddi gained a reputation as being physically powerful and fiercely loyal. This made them popular amongst the local princes as mercenaries.
Most of the original Siddis live in the Sindh region of Pakistan, and the Gujarat region of India, and some mixed with local Indian people.
Some of the dancers were dancing so passionately that it was clear that they had lost a sense of self and were truly a part of the group performance. Just like it should be.
