How are Mari Djata (Sundiata) and his famil mistreated after his father dies?

After the king dies, his eldest son, Dankaran Touman, is given control by the elders, who do not see much future in the crippled boy. One day, when Sogolon is embarrassed by the queen mother, Sundiata uses a rod to help himself stand on two legs and from this day onwards, his strength is unmistakable.

Frightened her own son will lose his control, the queen mother Sassouma Bérété orchestrates exile for Sundiata, Sogolon, and their immediate family. For seven years, they travel from asylum to asylum, sometimes being shown great hospitality and occasionally being mistreated by their hosts.
