Palanquins
According to researcher G. Reisiner, palanquins were used to carry Royals from one location to the other as it was believed they were too special to touch the ground. These palanquins were used in West Africa to carry chiefs and public officials like Governors in colonial eras.
Palanquins are still used in West Africa, especially in Ghana to transport Kings and chiefs from one place to another. It is believed that litters were developed from this technology. The sick and aged were also carried around with bed-like versions of palanquins.
