Problem: Tennessee is known as the "Volunteer State", a nickname some claimed was earned during the War of 1812 because of the prominent role played by volunteer soldiers from Tennessee, especially during the Battle of New Orleans. Other sources differ on the origin of the state nickname; according to the Columbia Encyclopedia, the name refers to volunteers for the MexicanAmerican War. This explanation is more likely, because President Polk's call for 2,600 nationwide volunteers at the beginning of the Mexican-American War resulted in 30,000 volunteers from Tennessee alone, largely in response to the death of Davy Crockett and appeals by former Tennessee Governor and now Texas politician, Sam Houston.
Which major conflict that included the Battle of New Orleans is said to have given Tennessee its nickname?

Answer: War of 1812

Problem: Queen Victoria:

By 1836, the Duchess's brother, Leopold, who had been King of the Belgians since 1831, hoped to marry his niece to his nephew, Prince Albert of Saxe-Coburg and Gotha. Leopold, Victoria's mother, and Albert's father (Ernest I, Duke of Saxe-Coburg and Gotha) were siblings. Leopold arranged for Victoria's mother to invite her Coburg relatives to visit her in May 1836, with the purpose of introducing Victoria to Albert. William IV, however, disapproved of any match with the Coburgs, and instead favoured the suit of Prince Alexander of the Netherlands, second son of the Prince of Orange. Victoria was aware of the various matrimonial plans and critically appraised a parade of eligible princes. According to her diary, she enjoyed Albert's company from the beginning. After the visit she wrote, "[Albert] is extremely handsome; his hair is about the same colour as mine; his eyes are large and blue, and he has a beautiful nose and a very sweet mouth with fine teeth; but the charm of his countenance is his expression, which is most delightful." Alexander, on the other hand, was "very plain".

The Dutchesses brother Leopold was the King of what country?

A:
the Belgians
