Question: Marie Depage was killed during an event that occurred in what year?

The sinking of the Cunard ocean liner RMS "Lusitania" occurred on Friday, 7 May 1915 during the World War 1, as Germany waged submarine warfare against the United Kingdom which had implemented a naval blockade of Germany.  The ship was identified and torpedoed by the German U-boat "U-20" and sank in 18 minutes.  The vessel went down 11 mi off the Old Head of Kinsale, Ireland, killing 1,198 and leaving 761 survivors.  The sinking turned public opinion in many countries against Germany, contributed to the American entry into World War I and became an iconic symbol in military recruiting campaigns of why the war was being fought. <SEP> The 2004 Grozny stadium bombing occurred on 9 May 2004 when a bomb exploded in the Dynamo stadium in the Chechen capital, Grozny, killing 10 people including the republic's president Akhmad Kadyrov and another 100 people were wounded.  Kadyrov's election was considered by many to be by a fraudulent vote.  The explosion was caused by a bomb planted underneath the concrete floor of the VIP podium and occurred at 10:35am during a parade and concert in Groznyy celebrating the 59th anniversary of the victory of Germany in World War 2.  The blast tore a hole in the section designated for dignitaries.  It was not clear if the explosion was specifically targeting Kadyrov or whether it would have occurred regardless of his presence, as he was not officially scheduled to be at this event.  Khussein Isayev, chairman of the Republic's state council, and Adlan Khasanov, a reported for Reuters, were also killed in the blast.  Col. Gen. Valery Baranov, the commander of the Russian military in the northern Caucasus was gravely wounded.  Although estimates of total casualties varied, at least ten people were killed and around fifty more injured.  The numbers include many civilians and WW2 veterans who were also attending the celebrations.  Officials believe that the blast was detonated by remote control and was intentionally installed below the VIP section.  The bomb may have been planted some time ago during the recent renovations to the stadium.  Preliminary reports suggest that the bomb was equivalent to one ton of TNT.  The location of the bomb made it impossible for existing equipment to detect.  The type of explosive appeared identical to one used to blow up the military parade two years ago in the Dagestani city of Kaspiysk.  Rescue workers prevented two other blasts in the stadium.  They were able to defuse another landmine and an additional explosive device equipped with a timer set to go off 30 minutes after the first explosion. <SEP> The Glina massacres were killings of Serb peasants in the town of Glina in the Independent State of Croatia (NDH) that occurred between May and August 1941, during World War II.  The first wave of massacres in the town began on 11 or 12 May 1941, when a band of Ustaše led by Mirko Puk murdered a group of Serb men and boys in a Serbian Orthodox church before setting it on fire.  The following day, approximately 100 Serb males were murdered by the Ustaše in the nearby village of Prekopi.  Estimates of the overall number of Serbs killed from 11–13 May range from 260 to 417.  Further killings in Glina occurred between 30 July and 3 August of that same year, when 700–2,000 Serbs were massacred by a group of Ustaše led by Vjekoslav Luburić.  Ljubo Jednak, the only survivor of these killings, went on to testify at the trials of the several prominent figures in the NDH after the war.  Puk was captured by British forces in 1945 while attempting to flee to Austria and was extradited to Yugoslavia the following year, where he committed suicide.  Luburić escaped Yugoslavia after the war and moved to fascist Spain, where he was killed by a person generally assumed to be an agent of the Yugoslav State Security Service. <SEP> Marie Pauline Depage (23 September 1872 – 7 May 1915) was a Belgian nurse, and wife of Dr Antoine Depage.
