A newsreel was a form of short documentary film prevalent in the first half of the 20th century, regularly released in a public presentation place and containing filmed news stories and items of topical interest. It was a source of news, current affairs and entertainment for millions of moviegoers until television supplanted its role in the 1950s. Newsreels are now considered significant historical documents, since they are often the only audiovisual record of historical and cultural events of those times.

Newsreels were typically featured as short subjects preceding the main feature film into the 1960s. There were dedicated newsreel theaters in many major cities in the 1930s and 1940s and some large city cinemas also included a smaller theatrette where newsreels were screened continuously throughout the day.

"The Black Dahlia" was a nickname given to Elizabeth Short (July 29, 1924 – January 15, 1947), an American woman who was the victim of a gruesome and much-publicized murder. Short acquired the moniker posthumously by newspapers in the habit of nicknaming crimes they found particularly colorful. Short was found mutilated, her body sliced in half at the waist, on January 15, 1947, in Leimert Park, Los Angeles, California. Short's unsolved murder has been the source of widespread speculation, leading to many suspects, along with several books and film adaptations of the story.

Elizabeth Short was born in greater Boston, Massachusetts; she grew up and lived in Medford. She was the third of five daughters of Cleo Short and Phoebe Mae Sawyer. Her father built miniature golf courses until the 1929 stock market crash, in which he lost much of the family's assets. In 1930, he parked his car on a bridge and vanished, leading some to believe he had committed suicide. Short's mother moved the family to a small apartment in Medford, and found work as a bookkeeper. It was not until later that Short would discover her father was alive and was living in California.

George V (George Frederick Ernest Albert; 3 June 1865 – 20 January 1936) was King of the United Kingdom and the British Dominions, and Emperor of India, from 6 May 1910 through the First World War (1914–1918) until his death in 1936.

George was a grandson of Queen Victoria and Prince Albert and the first cousin of Tsar Nicholas II of Russia and Kaiser Wilhelm II of Germany. From 1877 to 1891, he served in the Royal Navy. On the death of Victoria in 1901, George's father became King Edward VII, and George was made Prince of Wales. On his father's death in 1910, he succeeded as King-Emperor of the British Empire. He was the only Emperor of India to be present at his own Delhi Durbar.

As a result of the First World War, other empires in Europe fell while his expanded to its greatest extent. In 1917, he became the first monarch of the House of Windsor, which he renamed from the House of Saxe-Coburg and Gotha as a result of anti-German public sentiment. His reign saw the rise of socialism, communism, fascism, Irish republicanism, and the Indian independence movement, all of which radically changed the political landscape. The Parliament Act 1911 established the supremacy of the elected House of Commons of the United Kingdom over the unelected House of Lords. In 1924 he appointed the first Labour ministry and in 1931 the Statute of Westminster recognised the dominions of the Empire as separate, independent kingdoms within the Commonwealth of Nations. He was plagued by illness throughout much of his later reign and at his death was succeeded by his eldest son, Edward VIII.

World War I (WWI), which was predominantly called the World War or the Great War from its occurrence until 1939 (World War II), and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918. It involved all the world's great powers, which were assembled in two opposing alliances: the Allies (based on the Triple Entente of the United Kingdom, France and Russia) and the Central Powers (originally centred around the Triple Alliance of Germany, Austria-Hungary and Italy; but, as Austria–Hungary had taken the offensive against the agreement, Italy did not enter into the war). These alliances both reorganised (Italy fought for the Allies), and expanded as more nations entered the war. Ultimately more than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. More than 9 million combatants were killed, largely because of enormous increases in lethality of weapons, thanks to new technology, without corresponding improvements in protection or mobility. It was the sixth-deadliest conflict in world history, subsequently paving the way for various political changes such as revolutions in the nations involved.
