William Denby Hanna was an American animator, director, producer, voice actor, cartoon artist, and musician whose film and television cartoon characters entertained millions of people for much of the 20th century.

After working odd jobs in the first months of the Great Depression, Hanna joined the Harman and Ising animation studio in 1930. During the 1930s, Hanna steadily gained skill and prominence while working on cartoons such as Captain and the Kids. In 1937, while working at Metro-Goldwyn-Mayer, Hanna met Joseph Barbera. The two men began a collaboration that was at first best known for producing Tom and Jerry. In 1957, they co-founded Hanna-Barbera, which became the most successful television animation studio in the business, creating and/or producing programs such as The Flintstones, The Huckleberry Hound Show, The Jetsons, Scooby-Doo, The Smurfs, and Yogi Bear. In 1967, Hanna-Barbera was sold to Taft Broadcasting for $12 million, but Hanna and Barbera remained heads of the company until 1991. At that time, the studio was sold to Turner Broadcasting System, which in turn was merged with Time Warner in 1996; Hanna and Barbera stayed on as advisors.

Constantius II was Roman Emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.

The second son of Constantine I and Fausta, Constantius was made Caesar by his father in 324. He led the Roman army in war against the Sasanian Empire in 336. A year later, Constantine I died, and Constantius became Augustus with his brothers Constantine II and Constans. He promptly oversaw the massacre of eight of his relatives, consolidating his hold on power. The brothers divided the empire among themselves, with Constantius receiving the eastern provinces. In 340, his brothers Constantine and Constans clashed over the western provinces of the empire. The resulting conflict left Constantine dead and Constans as ruler of the west. The war against the Sasanians continued, with Constantius losing a major battle at Singara in 344. Constans was overthrown and assassinated in 350 by the usurper Magnentius.

The Battle of the Pyramids, also known as the Battle of Embabeh, was a major engagement fought on 21 July 1798 during the French Invasion of Egypt. The French army, under Napoleon Bonaparte, scored a decisive victory against the forces of the local Mamluk rulers, wiping out almost the entire Ottoman army located in Egypt. It was the battle where Napoleon employed one of his significant contributions to military tactics, the divisional square. Actually a rectangle, the deployment of the French brigades into these massive formations repeatedly threw back multiple cavalry charges by the Mamluks.

The victory effectively sealed the French conquest of Egypt as Murad Bey salvaged the remnants of his army, chaotically fleeing to Upper Egypt. French casualties amounted to roughly 300, but Ottoman and Mamluk casualties soared into the thousands. Napoleon entered Cairo after the battle and created a new local administration under his supervision. The battle exposed the fundamental military and political decline of the Ottoman Empire throughout the past century, especially compared to the rising power of France.
