Nader's Mesopotamian Campaign: The Mesopotamian Campaign of 1732-1733 was a military conflict during the eventful Perso-Ottoman war of 1730-1735.  As a direct result of Tahmasp II's blunders in his ill fated invasion of the Ottoman Caucasus all of Nader's previous gains in the theatre were lost and a humiliating treaty had been signed giving away hegemony over the Caucasus to Istanbul.  This settlement gave Nader the authority to force Tahmasp's abdication and resume the war against the Turks by launching an invasion of Ottoman Iraq.

Heart of the Ocean: The Heart of the Ocean (also known as Le Cœur de la Mer) is the name of a fictional blue diamond featured prominently in the 1997 film "Titanic".  In the story, the diamond was originally owned by Louis XVI and cut into a heart shape after the French Revolution.  In the film the necklace was purchased by Caledon Hockley, played by Billy Zane, a week before he sailed on the ill fated ocean liner Titanic.  The necklace was meant to be given as an engagement present to his fiancee Rose, played by Kate Winslet and Gloria Stuart.  It is believed that both Rose and the necklace went down with the ship, leading some of the main characters to believe the necklace lies somewhere within the wreckage of the Titanic.

Tahmasp's campaign of 1731: The campaign of 1731 was a failed attempt by Tahmasp II of the Safavid dynasty to launch an offensive into Ottoman held Caucasus which ended in a disastrous defeat with all of Nader's gains during the previous year being lost.  The result of this particular military catastrophe was still overturned with Nader's return from the east but would have much more significant impact on the Safavid dynasty itself as Tahmasp II sealed his own fate by initiating this ill fated expedition.

John Harlin: John Elvis Harlin II (June 30, 1935 – March 22, 1966) was an American mountaineer and US Air Force pilot who was killed while making an ascent of the north face of the Eiger.  Harlin graduated from Sequoia High School and Stanford University.  Having established himself as a top-rank mountaineer with the first American ascent of the Eiger North Face's Original Route in 1962 and the American Direct on the Dru, he conceived of climbing the Eiger by the "direttissima" (Italian for "most direct") route.  Two thousand feet from the summit his rope broke and he fell to his death.  The Scottish mountaineer Dougal Haston, who had been climbing with Harlin, reached the summit with a German party which joined forces to follow the same route, afterwards named the "Harlin route" in his honor.  The story of the climb was recounted in the book "" by British author (and ground team member) Peter Gillman and Dougal Haston.

1953 American Karakoram expedition: The 1953 American Karakoram expedition was a mountaineering expedition to K2, at 8,611 metres the second highest mountain on Earth.  It was the fifth expedition to attempt K2, and the first since the Second World War.  Led by Charles Houston, a mainly American team attempted the mountain's South-East Spur (commonly known as the Abruzzi Spur) in a style which was unusually lightweight for the time.  The team reached a high point of 7750 m, but were trapped by a storm in their high camp, where a team member, Art Gilkey, became seriously ill.  A desperate retreat down the mountain followed, during which all but one of the climbers were nearly killed in a fall arrested by Pete Schoening, and Gilkey later died in an apparent avalanche.  The expedition has been widely praised for the courage shown by the climbers in their attempt to save Gilkey, and for the team spirit and the bonds of friendship it fostered.
