Robin Wright on the significance of Neda's death:
The first clashes in January 1978 produced two deaths that were then commemorated on the 40th day in mass gatherings, which in turn produced new confrontations with security forces — and new deaths. Those deaths then generated another 40-day period of mourning, new clashes, and further deaths. The cycle continued throughout most of the year until the shah's ouster in January 1979.
The same cycle has already become an undercurrent in Iran's current crisis. The largest demonstration, on Thursday of last week, was called by opposition leader Mir Hossein Mousavi to commemorate the deaths of protesters three days after they were killed.
Shiite mourning is not simply a time to react with sadness. Particularly in times of conflict, it is also an opportunity for renewal. The commemorations for "Neda" and the others killed this weekend are still to come. And the 40th day events are usually the largest and most important.
