The Black Speech is one of the fictional languages constructed by J. R. R. Tolkien for his legendarium, where it was spoken in the evil realm of Mordor. In the fiction, Tolkien describes the language as being created by Sauron as a constructed language to be the sole language of all the servants of Mordor, thereby replacing (with little success) the many different varieties of Orkish, Westron, and other languages used by his servants. Tolkien describes the language as having two forms, the ancient "pure" forms used by Sauron himself, the Nazgûl, and the Olog-hai, and the more "debased" form used by the soldiery of Barad-dûr at the end of the Third Age.

Compare to the standardisation of Spanish undertaken by Nebrija

The Conqueror of Granada receives a petition, similar to many others. But unlike the request of Columbus, who wanted resources to establish a new route to the China of Marco Polo, that of Nebrija urges the Queen to invade a new domain at home. He offers Isabella a tool to colonize the language spoken by her own subjects; he wants her to replace the people’s speech by the imposition of the queen’s lengua – her language, her tongue.

[...] Together with Ferdinand, she was trying to give shape to the chaotic Castile they had inherited; together they were creating Renaissance institutions of government, institutions apt for the making of a modern state, and yet, something better than a nation of lawyers. Nebrija calls to their minds a concept that, to this day, is powerful in Spanish – armas y letras. He speaks about the marriage of empire and language, addressing the sovereign who had just recently – and for a painfully short time – seized from the Church the Inquisition, in order to use it as a secular instrument of royal power.
