Diocletian (Latin: Gaius Aurelius Valerius Diocletianus Augustus; c. 22 December 244  – 3 December 311), was a Roman Emperor from 284 to 305. Born to a family of low status in the Roman province of Dalmatia, Diocletian rose through the ranks of the military to become cavalry commander to the Emperor Carus. After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed Emperor. The title was also claimed by Carus' other surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus. With his accession to power, Diocletian ended the Crisis of the Third Century. He appointed fellow officer Maximian Augustus his senior co-emperor in 285.

The Crisis is the official magazine of the National Association for the Advancement of Colored People (NAACP), and was founded in 1910 by W. E. B. Du Bois (editor), Oswald Garrison Villard, J. Max Barber, Charles Edward Russell, Kelly Miller, W.S. Braithwaite, M. D. Maclean.

The original title of the journal was The Crisis: A Record of The Darker Races. From 1997 to 2003, it appeared as The New Crisis: The Magazine of Opportunities and Ideas, but the title has since reverted to The Crisis. The title derives from the poem "The Present Crisis" by James Russell Lowell. Published monthly, by 1920 its circulation had reached 100,000 copies. Du Bois proclaimed his intentions in his first editorial:

Predominantly a current-affairs journal, The Crisis also included poems, reviews, and essays on culture and history. Du Bois' initial position as editor was in line with the NAACP's liberal programme of social reform and racial equality, but by the 1930s Du Bois was advocating a form of black separatism. This led to disputes between Du Bois and the NAACP resulting in his resignation as editor in 1934. He was replaced by Roy Wilkins.
