Hārūn al-Rashīd (Arabic: هارون الرشيد‎; properly pronounced Hārūn ar-Rashīd; English: Aaron the Upright, Aaron the Just, or Aaron the Rightly Guided) (17 March 763 or February 766 – 24 March 809) was the fifth Arab Abbasid Caliph that encompassed modern Iraq. His birth date remains a point of discussion, though, as various sources give the dates from 763 to 766).

He ruled from 786 to 809, and his time was marked by scientific, cultural and religious prosperity. Art and music Hamd o Na'at also flourished significantly during his reign. He established the legendary library Bayt al-Hikma ("House of Wisdom").^{[citation needed]}

Since Harun was intellectually, politically and militarily resourceful, his life and the court over which he held sway have been the subject of many tales: some are factual but most are believed to be fictitious. An example of what is known to be factual is the story of the clock that was among various presents that Harun had sent to Charlemagne. The presents were carried by the returning Frankish mission that came to offer Harun friendship in 799. Charlemagne and his retinue deemed the clock to be a conjuration for the sounds it emanated and the tricks it displayed every time an hour ticked.^{[citation needed]} Among what is known to be fictional is The Book of One Thousand and One Nights, which contains many stories that are fantasized by Harun's magnificent court and even Harun al-Rashid himself.^{[citation needed]}

Sidney K. "Sid" Meier (born February 24, 1954) is a Canadian-American programmer and designer of several popular strategy video games and simulation video games, most notably Civilization. Meier co-founded MicroProse in 1982 and is a Director of Creative Development for computer game developer Firaxis Games, which he co-founded with Jeff Briggs and Brian Reynolds in 1996. He has won several prestigious accolades for his contributions to the computer games industry.

Sid Meier was born in Sarnia, Ontario, Canada. He graduated from the University of Michigan.

Meier founded MicroProse together with Bill Stealey in 1982. MicroProse initially developed flight simulator video games, such as Silent Service and F-19 Stealth Fighter. In 1987, the company released Sid Meier's Pirates!, which also began a trend of placing Meier's name in the titles of his games. Meier later explained that the inclusion of his name was because of the dramatic departure in the design of Pirates! compared to the company's earlier games. Stealey decided that it would improve the company's branding, believing that it would make those who purchased the flight simulators more likely to play Pirates!. After the release of F-19 Stealth Fighter, Meier decided to focus on developing strategy games. He later said, "Everything I thought was cool about a flight simulator had gone into that game." Inspired by SimCity and Empire!, Meier created Railroad Tycoon and later the game series for which he is most widely recognized, Civilization, although he designed only the first installment. Meier eventually left MicroProse and in 1996 founded Firaxis Games along with veteran designer and gaming executive Jeff Briggs. Today Firaxis makes strategy games, many of which are follow-ups to Meier titles, such as Civilization V and Pirates!. In 1996 he was awarded US Patent 5,496,962 for a "System for Real-Time Music Composition and Synthesis" used in a product called "CPU Bach".
