Fidel Castro is one of the world's influential leftist leaders. When he died on November 25, 2016, due to his aging and illness at the age of 90, Cubans and the world share mixed reactions: from celebration to mourning. However, there are always lots of reasons why the world commemorates Castro's life, death, and legacy.

Cubans will commemorate Castro's life during at mass memorial this week, which highlights the story of the late leader when he led the revolution almost sixty years ago. The funeral will be held on Sunday, December 4, 2016, at Santa Ifigenia cemetery in Santiago de Cuba,  the Havana TImes reports.

On Wednesday, Cubans will attend a ceremonial journey to salute to Castro's remains, starting from the route when Castro and his group assumed power from Fulgencio Batista in 1959.
