Herbert Bareuther (29 July 1914 – 30 April 1945) was a World War II fighter ace from Nazi Germany.
 He was born on 29 July 1914 at Asch in Egerland.
 Bareuther was credited with having shot down a total of 55 enemy aircraft.
 All the victories he achieved were recorded over the Eastern Front.
World War I (WWI or WW1), also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918.
 More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history.
 Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare.
 It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved.
 Unresolved rivalries still extant at the end of the conflict contributed to the start of the Second World War only twenty-one years later.
Zafir Premčević (; 1872—1937) was a Serbian Chetnik commander in Old Serbia and Macedonia during the Macedonian Struggle, who also participated in the Balkan Wars and World War I.
The Yugoslav monitor "Sava was a "Temes"-class river monitor built for the Austro-Hungarian Navy as SMS "Bodrog.
 She fired the first shots of World War I on the night of 28 July 1914, when she and two other monitors shelled Serbian defences near Belgrade.
 She was part of the Danube Flotilla, and fought the Serbian and Romanian armies from Belgrade to the mouth of the Danube.
 In the closing stages of the war, she was the last monitor to withdraw towards Budapest, but was captured by the Serbs when she grounded on a sandbank downstream from Belgrade.
 After the war, she was transferred to the newly created Kingdom of Serbs, Croats and Slovenes (later Yugoslavia), and renamed "Sava".
 She remained in service throughout the interwar period, although budget restrictions meant she was not always in full commission.
Ersilio Tonini (20 July 1914 – 28 July 2013) was an Italian Cardinal of the Catholic Church.
 He served as Archbishop of Ravenna-Cervia from 1975 to 1990, and was elevated to the cardinalate in 1994.
 When Cardinal Paul Augustin Mayer died on 30 April 2010, Cardinal Tonini became the oldest living cardinal.
 He died on 28 July 2013, a week after his 99th birthday.
Spain remained neutral throughout World War I between 28 July 1914 and 11 November 1918, and despite domestic economic difficulties, it was considered "one of the most important neutral countries in Europe by 1915".
 Spain had enjoyed neutrality during the political difficulties of pre-war Europe, and continued its neutrality after the war until the Spanish Civil War began in 1936.
 While there was no direct military involvement in the war, German forces were interned in Spanish Guinea in late 1915.
The centenary of the outbreak of World War I was commemorated in Europe in late July and early August 2014.
 A century earlier, the July Crisis, which occurred after the assassination of Archduke Franz Ferdinand, had culminated in Austria-Hungary declaring war on the Kingdom of Serbia, which Austria-Hungary blamed for the assassination, on 28 July 1914.
 Over the following days and weeks, this action and the invasion of Luxembourg and Belgium by the German Empire led to a succession of other declarations of war that drew the major European powers into a worldwide conflict.
 A century later, governments in Europe held a series of official commemorative events to mark the occasion.
Kenneth (Ken) Neate (28 July 1914 – 27 June 1997) was a renowned Australian operatic and concert tenor, opera producer and singing teacher, composer and author.
 He appeared at the Bayreuth Festival in 1963 as Loge in Rheingold and he was noted as a dramatic tenor in German, French, and Italian repertoire in opera houses in England, France, Italy, Austria, Germany, and Australia.
 His operatic career lasted 38 years, followed by ten years as lecturer in Voice and Opera Studies at the Richard Strauss Conservatorium in Munich.

Le Pays de France, subtitled "Organe des états généraux du tourisme" ("The Country of France - Organ of the Estates General for Tourism"), was a French newspaper of the First World War.

 As a monthly it only lasted for 3 issues, with the first on 10 May 1914 and the last in July 1914.
 It then became a weekly paper two months after the outbreak of war, on 12 November 1914, ceasing publication in 1919, with its final issue (numéro 219) on 26 December 1918.
 Resolutely patriotic in tone, it reported battles and the wartime experiences of France's soldiers and people in reports, battle maps and photographs.
