Joshua Sankara played Seeker for Burkina Faso’s National Team at the 2006 Quidditch World Cup.
His team having won the 2006 final match, Sankara was so popular that he was elected as Burkina Faso’s Minister for Magic. After a few days he resigned the post, in favour of continuing with his Quidditch career (Pm).
Joshua is a biblical name meaning "god is salvation" (QuickBabyNames).
His surname may refer to Thomas Sankara (1949-1987), who was President of Burkina Faso from 1983-1987 and a "charismatic and iconic figure of revolution" (Wikipedia).
