Lian Chongyu: Lian Chongyu (連重遇) (d. February 14, 945) was a general of the Chinese Five Dynasties and Ten Kingdoms Period state Min.  In 944, he and another general, Zhu Wenjin, assassinated the emperor Wang Yanxi (also known as Wang Xi, Emperor Jingzong).

Treaty of Brussol: The Treaty of Brussol (also known as the Treaty of Bruzolo) was signed on 10 April 1610 in Bruzolo between Charles Emmanuel I, Duke of Savoy, and Henry IV of France, inside the Castle of Bruzolo, (in Susa Valley, near Turin).  Based on the terms of the accord, both signatories agreed to combine their forces in order to remove the Spanish from Italy.  The agreement also dictated that the Duke of Mantua exchange the province of Casale Monferrato for the province of Cremona.  Also, the territories of Montferrat and Milan would be united under the control of Savoy.  Under the treaty, Victor Emmanuel would be restored to the throne of Lombardy.  Also, Henry IV would have his daughter marry Prince Victor Amadeus I and that the King of France, the Republic of Venice, and the Pope guarantee the Duke of Savoy the title of King of Lombardy.  However, this accord was never realized since Henry IV was assassinated by Ravaillac in May 1610.  Marie de' Medici, just crowned queen, fored the treaty.  Even though Henry's death ended the treaty, Charles Emmanuel seized Montferrat from the Spanish in 1613, which led to a war that lasted until 1617.

Assassination of James A. Garfield: James A. Garfield, the 20th President of the United States, was assassinated at 9:30 am on July 2, 1881, less than four months into his term as President.  He was shot by Charles J. Guiteau at the Baltimore and Potomac Railroad Station in Washington, D.C., and died in Elberon, New Jersey on September 19, 1881.  Guiteau's motive was revenge against Garfield for an imagined political debt.  Garfield was the second of four Presidents to be assassinated, following Abraham Lincoln and preceding William McKinley and John F. Kennedy.  His Vice President, Chester A. Arthur, succeeded Garfield as President.

William McKinley: William McKinley (January 29, 1843 – September 14, 1901) was the 25th President of the United States from March 4, 1897 until his assassination in September 1901, six months into his second term.  McKinley led the nation to victory in the Spanish–American War, raised protective tariffs to promote American industry, and maintained the nation on the gold standard in a rejection of inflationary proposals.

Warren Commission: The President's Commission on the Assassination of President Kennedy, known unofficially as the Warren Commission, was established by President Lyndon B. Johnson through Executive Order on November 29, 1963 to investigate the assassination of United States President John F. Kennedy that had taken place on November 22, 1963.  The U.S. Congress passed Senate Joint Resolution 137 authorizing the Presidential appointed Commission to report on the assassination of President John F. Kennedy, mandating the attendance and testimony of witnesses and the production of evidence.  Its 888-page final report was presented to President Johnson on September 24, 1964 and made public three days later.  It concluded that President Kennedy was assassinated by Lee Harvey Oswald and that Oswald acted entirely alone.  It also concluded that Jack Ruby also acted alone when he killed Oswald two days later.  The Commission's findings have proven controversial and have been both challenged and supported by later studies.

Johnson on Air Force One and for the flight back to Washington, D.C. with the President’s body.

Emperor Taiwu of Northern Wei: Emperor Taiwu of Northern Wei ((北)魏太武帝) (408–452), personal name Tuoba Tao (拓拔燾), nickname Bili (佛貍), was an emperor of Northern Wei.  He was generally regarded as a capable ruler, and during his reign, Northern Wei roughly doubled in size and united all of northern China, thus ending the Sixteen Kingdoms period and, together with the southern dynasty Liu Song, started the Southern and Northern Dynasties period of Chinese history.  He was a devout Taoist, under the influence of his prime minister Cui Hao, and in 444, at Cui Hao's suggestion and believing that Buddhists had supported the rebellion of Gai Wu (蓋吳), he ordered the abolition of Buddhism, at the penalty of death.  This was the first of the Three Disasters of Wu for Chinese Buddhism.  Late in his reign, his reign began to be cruel, and his people were also worn out by his incessant wars against Liu Song.  In 452, he was assassinated by his eunuch Zong Ai, who put his son Tuoba Yu on the throne but then assassinated Tuoba Yu as well.  The other officials overthrew Zong and put Emperor Taiwu's grandson Tuoba Jun (son of Tuoba Huang the Crown Prince, who predeceased him) on the throne as Emperor Wencheng.

1963 Togolese coup d'état: The 1963 Togolese coup d'état was a military coup that occurred in the country of Togo on 13 January 1963.  The coup leaders (notably Emmanuel Bodjolle, Étienne Eyadéma and Kléber Dadjo) took over government buildings, arrested most of the cabinet, and assassinated Togo's first President, Sylvanus Olympio outside the American embassy in Lomé.  The coup leaders quickly brought Nicolas Grunitzky and Antoine Meatchi, both of whom were exiled political opponents of Olympio, together to form a new government.  While the government of Ghana and its President Kwame Nkrumah were implicated in the coup and assassination of Olympio, full investigation was never completed and the international outcry eventually died down.  The event was important as the first coup d'état in the French and British colonies of Africa that achieved independence in the 1950s and 1960s, and Olympio is remembered as one of the first heads of state to be assassinated during a military coup in Africa.

Al-Ghashmi assumed power when his predecessor, Ibrahim al-Hamdi, was assassinated.  Ghashmi himself was assassinated later.  His assassination occurred when he was meeting an envoy sent by People's Democratic Republic of Yemen President Salim Rubai Ali and a briefcase, reportedly containing a secret message, exploded, killing both al-Ghashmi and the envoy.  It is not conclusively known who set off the explosion.  Coincidentally, Rubai Ali died in a coup three days after this event.
