Question: What is most often the purpose of the genre of literature that Jackboots on Whitehall belongs in?

Context paragraphs:
Electronic literature: Electronic literature or digital literature is a genre of literature encompassing works created exclusively on and for digital devices, such as computers, tablets, and mobile phones.  Some platforms of this new digitized world include blog fiction, twitterature as well as facebook stories.  This means that these writings cannot be easily printed, or cannot be printed at all, because elements crucial to the text are unable to be carried over onto a printed version.  The digital literature world continues to innovate print's conventions all the while challenging the boundaries between digitized literature and electronic literature.  Some novels are exclusive to tablets and smartphones for the simple fact that they require a touchscreen.  Digital literature tends to require a user to traverse through the literature through the digital setting, making the use of the medium part of the literary exchange.  Espen J. Aarseth wrote in his book "Cybertext: Perspectives on Ergodic Literature" that "it is possible to explore, get lost, and discover secret paths in these texts, not metaphorically, but through the topological structures of the textual machinery".

Biblical genre: A Biblical genre is a classification of Bible literature according to literary genre.  The genre of a particular Bible passage is ordinarily identified by analysis of its general writing style, tone, form, structure, literary technique, content, design, and related linguistic factors; texts that exhibit a common set of literary features (very often in keeping with the writing styles of the times in which they were written) are together considered to be belonging to a genre.  In Biblical studies, genres are usually associated with whole books of the Bible, because each of its books comprises a complete textual unit; however, a book may be internally composed of a variety of styles, forms, and so forth, and thus bear the characteristics of more than one genre (for example, chapter 1 of the Book of Revelation is prophetic/visionary; chapters 2 and 3 are similar to the epistle genre; etc.).

Whitehall Mystery: The Whitehall Mystery is an unsolved murder that took place in London in 1888.  The dismembered remains of a woman were discovered at three different sites in the centre of the city, including the future site of Scotland Yard, the police's headquarters.  The incident belongs to the so-called Thames Torso Murders of 1887–89.

Banqueting House, Whitehall: The Banqueting House, Whitehall, is the grandest and best known survivor of the architectural genre of banqueting house and the only remaining component of the Palace of Whitehall.  The building is important in the history of English architecture as the first structure to be completed in the neo-classical style, which was to transform English architecture.

Satire: Satire is a genre of literature, and sometimes graphic and performing arts, in which vices, follies, abuses, and shortcomings are held up to ridicule, ideally with the intent of shaming individuals, corporations, government, or society itself into improvement.  Although satire is usually meant to be humorous, its greater purpose is often constructive social criticism, using wit to draw attention to both particular and wider issues in society.

History (theatrical genre): History is one of the three main genres in Western theatre alongside tragedy and comedy, although it originated, in its modern form, thousands of years later than the other primary genres.  For this reason, it is often treated as a subset of tragedy.  A play in this genre is known as a history play and is based on a historical narrative, often set in the medieval or early modern past.  History emerged as a distinct genre from tragedy in Renaissance England.  The best known examples of the genre are the history plays written by William Shakespeare, whose plays still serve to define the genre.  History plays also appear elsewhere in British and Western literature, such as Thomas Heywood's "Edward IV", Schiller's "Mary Stuart" or the Dutch genre "Gijsbrecht van Aemstel".

Mathematical fiction: Mathematical fiction is a genre of creative fictional work in which mathematics and mathematicians play important roles.  The form and the medium of the works are not important.  The genre may include short stories, novels or plays; comic books; films, videos, or audios.  One of the earliest, and much studied, work of this genre is , an 1884 satirical novella by the English schoolmaster Edwin Abbott Abbott.  Mathematical fiction may have existed since ancient times, but it was recently rediscovered as a genre of literature; since then there has been a growing body of literature in this genre, and the genre has attracted a growing body of readers.  For example, Abbot's Flatland spawned a sequel in the 21st century: a novel titled "Flatterland", authored by Ian Stewart and published in 2001.

Descriptive poetics: Descriptive poetics is an analytic approach within literary studies.  While the concept of "poetics" goes back to Aristotle, the term descriptive poetics refers to an approach which, according to Brian McHale, represents a middle ground between theoretically oriented approaches and analyses of individual works of literature.  To McHale, the purpose of descriptive poetics is to give exhaustive accounts of different kinds of objects which can be a group of texts, the entire production of a single author, a particular genre, the style of a period in literary history or even specific styles of literature.  McHale argues that the approach is not defined by what it examines but by the level of "generalization" achieved in this form of literary studies.  The approach was given a formalized forum in the journal "PTL: A Journal of Descriptive Poetics and Theory of Literature" which only had a short run before it was succeeded by the more successful journal "Poetics Today".  According to literary scholar Uni Margolin, descriptive poetics was a rather prominent form of scholarship in the first half of the 20th century, especially in Germany, but has since "been neglected since 1968 because of its low level of theoretisation".
