942 – Assassination of William I of Normandy

17 December

William I Longsword (c. 893 – 17 December 942) was the second ruler of Normandy, from 927 until his assassination.

He is sometimes anachronistically dubbed "Duke of Normandy", even though the title duke (dux) did not come into common usage until the 11th century. William was known at the time by the title count (Latin comes) of Rouen. Flodoard—always detailed about titles—consistently referred to both Rollo and his son William as principes (chieftains) of the Norse.

The Assassination:

William Longsword attacked Flanders in 939 and Arnulf I, Count of Flanders, and Louis IV, King of France, retaliated by attacking Normandy. Arnulf captured the castle of Montreuil-sur-Mer expelling Herluin, Count of Ponthieu. Herluin and William Longsword cooperated to retake the castle. William was excommunicated for his actions in attacking and destroying several estates belonging to Arnulf.

William pledged his loyalty to King Louis IV when they met in 940 and, in return, he was confirmed in lands that had been given to his father, Rollo. Almost three years later, on 17 December 942 at Picquigny on the Somme, William Longsword was ambushed and killed by followers of Arnulf while at a peace conference to settle their differences.

1980 – John Lennon is murdered

8 December

At around 10:50 pm on this day in 1980, as Lennon and Ono returned to their New York apartment in the Dakota, Mark David Chapman shot Lennon in the back four times at the entrance to the building. Lennon was taken to the emergency room of nearby Roosevelt Hospital and was pronounced dead on arrival at 11:00 pm. Earlier that evening, Lennon had autographed a copy of Double Fantasy for Chapman.

Ono issued a statement the next day, saying "There is no funeral for John", ending it with the words, "John loved and prayed for the human race. Please pray the same for him." His body was cremated at Ferncliff Cemetery in Hartsdale, New York. Ono scattered his ashes in New York's Central Park, where the Strawberry Fields memorial was later created. Chapman pleaded guilty to second-degree murder and was sentenced to 20 years to life. As of 2015, he remains in prison, having been denied parole eight times.

P.S. Decided to go with an image from 1980 for the feature picture.

43 BC – Marcus Tullius Cicero is assassinated

7 December

Marcus Tullius Cicero (3 Jan 106 BC – 7 Dec 43 BC) was a Roman philosopher, politician, lawyer, orator, political theorist, consul and constitutionalist. He came from a wealthy municipal family of the Roman equestrian order, and is widely considered one of Rome's greatest orators and prose stylists.

Though he was an accomplished orator and successful lawyer, Cicero believed his political career was his most important achievement. It was during his consulship that the Second Catilinarian Conspiracy attempted to overthrow the government through an attack on the city by outside forces, and Cicero suppressed the revolt by executing five conspirators without due process. During the chaotic latter half of the 1st century BC marked by civil wars and the dictatorship of Gaius Julius Caesar, Cicero championed a return to the traditional republican government. Following Julius Caesar's death Cicero became an enemy of Mark Antony in the ensuing power struggle, attacking him in a series of speeches. He was proscribed as an enemy of the state by the Second Triumvirate and consequently executed by soldiers operating on their behalf in 43 BC after having been intercepted during attempted flight from the Italian peninsula. His severed hands and head were then, as a final revenge of Mark Antony, displayed in the Roman Forum.
