The Janissaries (Ottoman Turkish: يڭيچرى yeniçeri, meaning "new soldier") were elite infantry units that formed the Ottoman Sultan's household troops and bodyguards. Sultan Murad I created the force in 1383. The number of Janissaries grew from 20,000 in 1575, to 49,000 (1591), dropped to a low of 17,000 (1648), then rebounded to 135,000 in 1826.
They began as an elite corps of slaves recruited from young Christian boys, and became famed for internal cohesion cemented by strict discipline and order. By 1620 they were hereditary and corrupt and an impediment to reform. The corps was abolished by Sultan Mahmud II in 1826 in the Auspicious Incident in which 6,000 or more were executed.
Some historians such as Patrick Kinross date the formation of the Janissaries to around 1365, during the rule of Orhan's son Murad I, the first sultan of the Ottoman Empire. The Janissaries became the first Ottoman standing army, replacing forces that mostly consisted of tribal warriors (ghazis) whose loyalty and morale were not always guaranteed.
Janissaries is a novel by science fiction author Jerry Pournelle. It was originally published in 1979, and was illustrated by comic artist Bermejo. It is the first book of Pournelle's Janissaries series. The following books are Janissaries: Clan and Crown and Janissaries III: Storms of Victory.
Like King David's Spaceship, a novel in Pournelle's CoDominium Series, it is the story of a capable military leader undertaking campaigns on a backward planet.
In Janissaries, the leader is a United States Army officer from the Cold War period, Captain Rick Galloway, who along with his platoon-sized unit of soldiers primarily from the U.S. are abducted from a CIA-run operation against Cubans in the fictional tropical African country of Sainte-Marie by a flying saucer. The beings abducting them present themselves as rescuers from a hopeless situation where Galloway's unit is about to be overrun by Cubans in a night assault, the aftermath of which is expected to be the deaths of all. Afterwards, the human soldiers have the option of serving the aliens in a special situation involving a more primitive planet on which there are humans living in medieval conditions. The soldiers are expected to be able to use their superior weapons and tactics to conquer part of the planet.
