Omar Koshan

Omar Koshan is a Twelver Shi'i festival marking the end of the mourning period following the death of Husayn ibn Ali at Karbala in 680 AD. Through the 2020 snapshot the opening described this period as following 'the events of the Karbala massacre, which occurred in 680 AD.' Today the opening calls the same event the Battle of Karbala, and massacre appears nowhere in the article. A reader arriving now learns it was a battle, and not that Wikipedia's own opening once named it a massacre.
