In June 1789…
… the members of the French Third Estate assembled, vowing to obtain a constitution, thus launching the French Revolution.

… nineteen-year-old Ukrainian Ulyana Gromova was executed by the Nazis and thrown into a pit, together with fellow members of the resistance in her village.

The 2011 performance was extraordinarily stopped by the director Riccardo Muti after the famous aria, and he subsequently expressed his concern that the lyrics “O, my homeland, so beautiful and lost!” could soon ring too familiar during a time when funds for culture were being cut. He then turned his back to the stage and directed an emotional encore, sung this time by the entire hall.
