While the overall concept of orcs draws on a variety of pre-existing mythology, the main conception of the creatures stems from the fantasy writings of J. R. R. Tolkien, in particular "The Lord of the Rings".

Orc (Middle-earth)
In J. R. R. Tolkien's fantasy writings, Orcs are a race of creatures who are used as soldiers and henchmen by both the greater and lesser villains of "The Silmarillion", "The Hobbit" and "The Lord of the Rings"—Morgoth, Sauron and Saruman. Although not entirely dim-witted and occasionally crafty, they are portrayed as miserable beings, hating everyone including themselves and their masters, whom they serve out of fear. They make no beautiful things, but rather design cunning devices made to hurt and destroy. In some of his unpublished early work, Tolkien appears to distinguish orcs from goblins.
Middle-earth wars and battles
J. R. R. Tolkien's Middle-earth fantasy writings include many wars and battles set in the lands of Aman, Beleriand, Númenor, and Middle-earth. These are related in his various books such as "The Hobbit" and "The Lord of the Rings", and "The Silmarillion", "Unfinished Tales" and other posthumously published books edited by his son Christopher Tolkien. These are given below in an in-universe, fictional chronology:  The Kinslayings are the collective term for the three battles fought between the Eldar. The first battle, the Kinslaying at Alqualondë (Swanhaven), appears in print in "The Silmarillion".
Orc
An orc (also spelled as ork) is a fictional humanoid creature that is part of a fantasy race akin to goblins. While the overall concept of orcs draws on a variety of pre-existing mythology, the main conception of the creatures stems from the fantasy writings of J. R. R. Tolkien, in particular "The Lord of the Rings". In Tolkien's works, orcs are a brutish, aggressive, repulsive and generally malevolent species, existing in stark contrast with the benevolent Elvish race and generally serve an evil power. Tolkien's concept of orcs has subsequently been adapted and imported into other works of fantasy fiction as well as role-playing and strategy games (such as "Dungeons & Dragons", "Warhammer", and "Warcraft"), broadening the recognition of the creatures in popular culture.
Middle-earth
Middle-earth is the fictional setting of much of British writer J. R. R. Tolkien's legendarium. The term is equivalent to the term "Midgard" of Norse mythology, describing the human-inhabited world, i.e. the central continent of the Earth in Tolkien's imagined mythological past. Tolkien's most widely read works, "The Hobbit" and "The Lord of the Rings", take place entirely in Middle-earth, and "Middle-earth" has also become a short-hand to refer to the legandarium and Tolkiens fictional take on the world. Within his stories, Tolkien translated the name "Middle-earth" as "Endor" (or sometimes "Endórë") and "Ennor" in the Elvish languages Quenya and Sindarin respectively, sometimes referring only to the continent that the stories take place on, with another southern continent called the Dark Land.

Aegwynn grew powerful over the years and used her powers to extend her life significantly.
The Lord of the Rings
The Lord of the Rings is an epic high fantasy novel written by English author and scholar J. R. R. Tolkien. The story began as a sequel to Tolkien's 1937 fantasy novel "The Hobbit", but eventually developed into a much larger work. Written in stages between 1937 and 1949, "The Lord of the Rings" is one of the best-selling novels ever written, with over 150 million copies sold. The title of the novel refers to the story's main antagonist, the Dark Lord Sauron, who had in an earlier age created the One Ring to rule the other Rings of Power as the ultimate weapon in his campaign to conquer and rule all of Middle-earth.
Sauron
Sauron is the title character and main antagonist of J. R. R. Tolkien's "The Lord of the Rings". In the same work, he is identified as the Necromancer, mentioned in Tolkien's earlier novel "The Hobbit". In Tolkien's "The Silmarillion" (published posthumously by Tolkien's son Christopher Tolkien), he is also described as the chief lieutenant of the first Dark Lord, Morgoth. Tolkien noted that the Ainur, the "angelic" powers of his constructed myth, "were capable of many degrees of error and failing", but by far the worst was "the absolute Satanic rebellion and evil of Morgoth and his satellite Sauron".

Okay sure. They are often characterized as a vicious and ferocious creature. I hear they eat their own kinds?
0_Wizard
that could be true. References go as far back as the 16th century, so I'm sure they have done that. 
Earlier references to creatures etymologically or conceptually similar to orcs can be found in Anglo-Saxon sources; including "Beowulf" and 16th-century Italian folk tales, in particular those of Giambattista Basile.

History of gunpowder
Gunpowder is the first physical explosive and propellant. Before its invention, many incendiary and burning devices had been used, including Greek fire. The invention of gunpowder is attributed to experimentation in Chinese alchemy by Taoists in the pursuit of immortality, and is popularly listed as one of the "Four Great Inventions" of China. It was invented during the late Tang dynasty (9th century) but the earliest record of a written formula appeared in the Song dynasty (11th century). Knowledge of gunpowder spread rapidly throughout the Old World possibly as a result of the Mongol conquests during the 13th century, with written formula for it appearing in the 1267 "Opus Majus" treatise by Roger Bacon and a 1280 treatise by Hasan al-Rammah.
Galley
Galleys were the warships used by the early Mediterranean naval powers, including the Greeks, Phoenicians and Romans. They remained the dominant types of vessels used for war and piracy in the Mediterranean Sea until the last decades of the 16th century. As warships, galleys carried various types of weapons throughout their long existence, including rams, catapults and cannons, but also relied on their large crews to overpower enemy vessels in boarding actions. They were the first ships to effectively use heavy cannons as anti-ship weapons. As highly efficient gun platforms they forced changes in the design of medieval seaside fortresses as well as refinement of sailing warships.
Early Netherlandish painting
Early Netherlandish painting is the work of artists, sometimes known as the Flemish Primitives, active in the Burgundian and Habsburg Netherlands during the 15th- and 16th-century Northern Renaissance; especially in the flourishing cities of Bruges, Ghent, Mechelen, Louvain, Tournai and Brussels, all in contemporary Belgium. Their work follows the International Gothic style and begins approximately with Robert Campin and Jan van Eyck in the early 1420s. It lasts at least until the death of Gerard David in 1523, although many scholars extend it to the start of the Dutch Revolt in 1566 or 1568 (Max J. Friedländer's acclaimed surveys run through Pieter Bruegel the Elder).
Sidney Psalms
The Sidney Psalms or Sidneian Psalms was a 16th-century translation into English of the Psalms. It was the work of Philip and Mary Sidney, aristocratic siblings who were very influential Elizabethan poets. Mary Sidney completed the book and gave a copy to Queen Elizabeth I of England in 1599. They were celebrated in the work of John Donne. Psalm one is the first Psalm in the Sidney Psalter, written by brother and sister, Phillip and Mary Sidney in the 16th. Psalm One, as discussed here, was written by Phillip Sidney in the late 1500s. It is a poetic adaption of psalm one from the biblical book of psalms.
Italian literature
Italian literature is written in the Italian language, particularly within Italy. It may also refer to literature written by Italians or in Italy in other languages spoken in Italy, often languages that are closely related to modern Italian. An early example of Italian literature is the tradition of vernacular lyric poetry performed in Occitan, which reached Italy by the end of the 12th century. In 1230, the Sicilian School is notable for being the first style in standard Italian. Dante Alighieri, one of the greatest of Italian poets, is notable for his "Divine Comedy". Petrarch did classical research and wrote lyric poetry.
Aristocracy of Norway
Aristocracy of Norway refers to modern and medieval aristocracy in Norway. Additionally, there have been economical, political, and military élites that—relating to the main lines of Norway's history—are generally accepted as nominal predecessors of the aforementioned. Since the 16th century, modern aristocracy is known as nobility (). The very first aristocracy in today's Norway appeared during the Bronze Age (c. 1800 BCc. 500 BC). This bronze aristocracy consisted of several regional élites, whose earliest known existence dates to c. 1500 BC. Via similar structures in the Iron Age (c. 400 BCc.
Comma Johanneum
The Comma Johanneum, also called the Johannine Comma or the Heavenly Witnesses, is a comma (a short clause) found in Latin manuscripts of the First Epistle of John at . The comma first appeared in the Vulgate manuscripts of the 9th century. The first Greek manuscript that contains the comma dates from the 15th century. The comma is absent from the Ethiopic, Aramaic, Syriac, Slavic, Armenian, Georgian, and Arabic translations of the Greek New Testament. The scholarly consensus is that that passage is a Latin corruption that entered the Greek manuscript tradition in some subsequent copies. As the comma does not appear in the manuscript tradition of other languages, the debate is mainly limited to the English-speaking world due to the King James Only movement.

The 16th century? Wow I am surprised. I wonder who first thought of the creatures back then. Or they may be a mythological creature I guess?

Beowulf
Beowulf ( ) is an Old English epic poem consisting of 3,182 alliterative lines. It may be the oldest surviving long poem in Old English and is commonly cited as one of the most important works of Old English literature. A date of composition is a matter of contention among scholars; the only certain dating pertains to the manuscript, which was produced between 975 and 1025. The author was an anonymous Anglo-Saxon poet, referred to by scholars as the ""Beowulf" poet". The poem is set in Scandinavia. Beowulf, a hero of the Geats, comes to the aid of Hrothgar, the king of the Danes, whose mead hall in Heorot has been under attack by a monster known as Grendel.
The dragon (Beowulf)
The final act of the Anglo-Saxon poem "Beowulf" is about the hero Beowulf's fight with a dragon, the third monster he encounters in the epic. On his return from Heorot, where he killed Grendel and Grendel's mother, Beowulf becomes king of the Geats and rules peacefully for fifty winters until a slave awakens and angers a dragon by stealing a jewelled cup from its lair in order to gain freedom from killing his brother. When the angry dragon mercilessly burns the Geats' homes and lands, Beowulf decides to fight and kill the monster personally. He and his thanes climb to the dragon's lair where, upon seeing the beast, the thanes flee in terror, leaving only Wiglaf to battle at Beowulf's side.
Beowulf (2007 film)
Beowulf is a 2007 British-American 3D adult animated epic fantasy film directed by Robert Zemeckis and written by Neil Gaiman and Roger Avary, based on the Old English epic poem of the same name. The film was created through a motion capture process similar to the technique Zemeckis used in "The Polar Express". The cast includes Ray Winstone, Anthony Hopkins, Robin Wright Penn, Brendan Gleeson, John Malkovich, Crispin Glover, Alison Lohman, and Angelina Jolie. It was released in the United Kingdom and United States on November 16, 2007, by Paramount Pictures and Warner Bros. Pictures, and was available to view in IMAX 3D, RealD, Dolby 3D and standard 2D format.
Old English literature
Old English literature or Anglo-Saxon literature, encompasses literature written in Old English, in Anglo-Saxon England from the 7th century to the decades after the Norman Conquest of 1066. "Cædmon's Hymn", composed in the 7th century, according to Bede, is often considered the oldest extant poem in English, whereas the later poem, "The Grave" is one of the final poems written in Old English, and presents a transitional text between Old and Middle English. The "Peterborough Chronicle" can also be considered a late-period text, continuing into the 12th century. The poem "Beowulf", which often begins the traditional canon of English literature, is the most famous work of Old English literature.
Hrothgar
Hrothgar ( ; ) was a legendary Danish king living in the early 6th century. Hrothgar appears in the Anglo-Saxon epics "Beowulf" and "Widsith", in Norse sagas and poems, and in medieval Danish chronicles. In both Anglo-Saxon and Scandinavian tradition, Hrothgar is a Scylding, the son of Halfdan, the brother of Halga, and the uncle of Hrólfr Kraki. Moreover, in both traditions, the mentioned characters were the contemporaries of the Swedish king Eadgils; and both traditions also mention a feud with men named Fróði and Ingeld. The consensus view is that Anglo-Saxon and Scandinavian traditions describe the same person.
Beowulf: The Monsters and the Critics
""Beowulf": The Monsters and the Critics" was a 1936 lecture given by J. R. R. Tolkien on literary criticism on the Old English heroic epic poem "Beowulf". It was first published as a paper in that year in the "Proceedings of the British Academy", and has since been reprinted in many collections. Tolkien argues that the original poem has almost been lost under the weight of the scholarship on it; that "Beowulf" must be seen as a poem, not just as a historical document; and that the quality of its verse and its structure give it a powerful effect. He rebuts suggestions that the poem is an epic or exciting narrative, likening it instead to a strong masonry structure built of blocks that fit together.
J. R. R. Tolkien
John Ronald Reuel Tolkien, (; 3 January 1892 – 2 September 1973) was an English writer, poet, philologist, and university professor who is best known as the author of the classic high-fantasy works "The Hobbit", "The Lord of the Rings", and "The Silmarillion". He served as the Rawlinson and Bosworth Professor of Anglo-Saxon and Fellow of Pembroke College, Oxford, from 1925 to 1945 and Merton Professor of English Language and Literature and Fellow of Merton College, Oxford, from 1945 to 1959. He was at one time a close friend of C. S. Lewis—they were both members of the informal literary discussion group known as the Inklings.
