Today is the Aga Khan's 71st birthday, and this year marks his Golden Jubilee celebration of 50 years on the throne of Imamat. The Aga Khan is the spiritual leader of the Ismaili Muslims, and looks after both the spiritual and material/secular well-being of his followers.
It is quite remarkable that any leader fulfills 50 years of service, and this gentleman has made major contributions to world peace and economic development.
Here is a clip from a Canadian broadcast wishing the Aga Khan a happy birthday. There has been a close relationship between the Ismaili community and Canada since the time Canada served as a refuge for Ismailis who were expelled from Uganda by Idi Amin in 1972.
