Answer the question at the end by quoting:

Dr. Victor Von Doom (commonly known as Doctor Doom, or simply Doom) is a fictional character appearing in American comic books published by Marvel Comics. The son of a Romani witch, Von Doom has been depicted as a supervillain, the archenemy of the Fantastic Four, and the leader of the fictional nation called Latveria. While his chief opponents have been the Fantastic Four, he has also come into conflict with Spider-Man, Iron Man, Black Panther, and multiple others. Von Doom has also been depicted as a superhero, being the third character to take up the mantle of Iron Man and joining the Avengers.
On many occasions, Doom's only real weakness has been his arrogance. Layla Miller once reflected that Doom is incapable of accepting that he himself might be the reason for his failures. This is most keenly reflected in Doom's continued refusal to accept responsibility for the accident that fully scarred his face, instead preferring to blame Reed Richards for sabotaging his experiment. While his high opinion of himself is generally accurate, he is generally unable to accept when others may have a better understanding of a situation than he does - with the occasional exception of hearing the recommendations of heroes such as Mister Fantastic or the Thing when it is to his advantage. Even when teaming up with others against a greater threat, Doom will often try to subvert the alliance for personal gain. For instance, while allied with Adam Warlock and other heroes against the Titan Thanos, he attempted to steal Thanos' Infinity Gauntlet before its owner had been defeated.  Von Doom adheres to a strict code of honor at all times. However, Von Doom will keep his exact word, which may or may not be beneficial to the person to whom he has given his promise. For example, Doom may swear that he will not harm an individual, but that only means he will not personally harm that person; it does not mean he will prevent others from harming that person.  Doom's honor code led him to save Captain America from drowning because Captain America had earlier saved his life, and on another occasion he thanked Spider-Man for saving him from terrorists attacking him in an airport by allowing him to leave alive despite Spider-Man subsequently insulting him. His code of honor also means that he will not attack a respected opponent who is weakened or at a severe disadvantage, as he regards any victory resulting from such circumstances as hollow and meaningless. He has even on several occasions battled opponents who were intent on killing the Fantastic Four, for no other reason than the fact that he does not want the ultimate defeat of the Fantastic Four to come from anyone's hands but his own.  Victor von Doom has been shown to be devoted to the welfare and well-being of his subjects. Once, he even went so far as to let his soul lay bare and be judged by the Panther God of Wakanda, who determined that he genuinely wished for a utopian future where humanity thrived,

IN: Franz Joseph was born in the Schonbrunn Palace in Vienna, the eldest son of Archduke Franz Karl (the younger son of Holy Roman Emperor Francis II), and his wife Princess Sophie of Bavaria. Because his uncle, from 1835 the Emperor Ferdinand, was weak-minded, and his father unambitious and retiring, the young Archduke "Franzl" was brought up by his mother as a future Emperor with emphasis on devotion, responsibility and diligence. Franzl came to idolise his grandfather, der Gute Kaiser Franz, who had died shortly before the former's fifth birthday, as the ideal monarch. At the age of thirteen, Franzl started a career as a colonel in the Austrian army.

On 28 June 1914 Franz Joseph's nephew and heir Archduke Franz Ferdinand, and his morganatic wife Sophie, Duchess of Hohenberg, were assassinated by Gavrilo Princip, a Yugoslav nationalist of Serbian ethnicity, during a visit to Sarajevo. When he heard the news of the assassination, Franz Joseph said that "one has not to defy the Almighty. In this manner a superior power has restored that order which I unfortunately was unable to maintain."  While the emperor was shaken, and interrupted his holiday to return to Vienna, he soon resumed his vacation at his imperial villa at Bad Ischl. Initial decision-making during the "July Crisis" fell to Count Leopold Berchtold, the Austrian foreign minister; Count Franz Conrad von Hotzendorf, the chief of staff for the Austro-Hungarian army and the other ministers. The ultimate resolution of deliberations by the Austrian government during the weeks following the assassination of the Archduke was to give Serbia an ultimatum of itemized demands which it was virtually certain Serbia would be unable or unwilling to comply with, thus serving as a "legal basis for war." However, the general movement toward war with Serbia was already in motion prior to assassination of the Archduke as evidenced by a June 14 memo of Berchtold recommending the "elimination of Serbia" as a state, which Franz Josef expressed agreement with in a letter delivered to Kaiser Wilhelm II in Berlin on July 5. In that letter, Franz Josef "...explicitly stated that the decision for war against Serbia had been made before the assassination of the Archduke, and that the events of Sarajevo only confirmed the already pre-existing need for a war."  A week after delivery of the Austrian ultimatum to Serbia, on 28 July, Austria-Hungary declared war on Serbia. Within weeks, the Germans, Russians, French and British had all entered the fray which eventually became known as World War I.

so who started the first battle of the WWI?
