story: The Crimean War was a military conflict fought between October 1853 March 1856 in which Russia lost to an alliance of France, the United Kingdom, the Ottoman Empire, and Sardinia. The immediate cause involved the rights of Christian minorities in the Holy Land, which was controlled by the Ottoman Empire. The French promoted the rights of Catholics, while Russia promoted those of the Eastern Orthodox Christians. The longer-term causes involved the decline of the Ottoman Empire and the unwillingness of the United Kingdom and France to allow Russia to gain territory and power at Ottoman expense. It has widely been noted that the causes, in one case involving an argument over a key, have never revealed a "greater confusion of purpose", yet led to a war noted for its "notoriously incompetent international butchery."

While the churches eventually worked out their differences and came to an initial agreement, both Nicholas I of Russia and Napoleon III refused to back down. Nicholas issued an ultimatum that the Orthodox subjects of the Empire be placed under his protection. Britain attempted to mediate, and arranged a compromise that Nicholas agreed to. When the Ottomans demanded changes, Nicholas refused and prepared for war. Having obtained promises of support from France and Britain, the Ottomans officially declared war on Russia in October 1853., question: What two people didn't?

Ex Output:
Nicholas I of Russia and Napoleon III

story: A man has been charged with a federal hate crime in connection with what authorities say was a racially motivated "knockout" assault against an elderly black man, the U.S. Justice Department said Thursday.

Conrad Alvin Barrett, 27, of Katy, Texas, has been charged with one count of violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act.

According to the federal complaint, Barrett attacked the 79-year-old man "because of the man's race and color." He will next appear in court Friday afternoon for a detention hearing.

The suspect made a video of the attack November 24, the complaint said. In the video, he allegedly commented that "the plan is to see if I were to hit a black person, would this be nationally televised?"

He then allegedly "hit the man with such force that the man immediately fell to the ground. Barrett then laughed and said 'knockout,' as he ran to his vehicle and fled."

The victim suffered two jaw fractures and was hospitalized for several days, the complaint said.

Barrett's attorney, George Parnham, told CNN the affidavit does not "pull back the layers of mental health."

His client has bipolar disorder and takes medication, Parnham said in an earlier call.

Parnham said he could not state whether his client carried out the attack, but, "mental health issues definitely played a part in anything that occurred."

Barrett "is very sorry for this person," Parnham said, adding that he and his client haven't had much opportunity to discuss the facts of the case. , question: What kind of hate crime?

Ex Output:
knockout" assault
