Question: Passage: When Isabella first became queen, she was only three years old. The queen mother, Maria Christina of the Two Sicilies, served as regent. The first and foremost political division of the Isabeline era was between Carlists and Cristinos (or Isabelinos), the former being supporters of Infante Carlos, Count of Molina, a rival claimant to the throne and the latter being supporters of Maria Christina and Isabella. The former supported absolute monarchism and the traditionalism of the Antiguo Régimen ("Old Regime"); they were uniformly close to the Roman Catholic Church, and generally clericalist. The latter were generally supporters of constitutional monarchy (although some, including Maria Christina herself, were more inclined toward enlightened absolutism); they were liberals of one stripe or another, ranging from liberal conservatives and those whose liberalism was strictly economic to social liberals. In the 1830s, these two groups faced off in the First Carlist War, which the Cristinos won. The terms of surrender—notably the Convention of Vergara—left an opportunity for relatively moderate Carlists to continue to play a role in the country's politics, and many did so over the ensuing decades.

Question: Passage: Walter "Wiley" Jones was born in Madison County in northeastern Georgia, on July 14, 1848. His parents were George Jones, a white planter, and Jones' slave, Anne, who had six children by George Jones: Matthew (who superintended the construction of the Wiley Jones Street Car Line), Thomas, Julia (wife of Ben Reed), Wiley, Taylor, and James (who managed many of Wiley's businesses). Wiley received his nickname because of his mischievous nature. At the age of five, he moved to Arkansas with his master and more than forty fellow slaves. They settled on the Governor Byrd plantation. George Jones died in 1858. Anne was called his wife in an 1889 biography of Jones, and she believed that George had promised to free herself and her children upon his death, but no manumission papers were found, and the family was kept as slaves and sold by the estate administer, Peter Finerty, to James Yell, a lawyer and planter in Pine Bluff. Jones worked as a houseboy and carriage driver for his new master. When Jones was ten, he was given to Yell's only son, Fountain Pitts Yell, on the occasion of Pitts Yell's marriage. Pitts was a state representative from 1860 to 1861. During the American Civil War, James Yell became a Major General of the Arkansas State Militia, and Pitts became a colonel in Company S of the 26th Arkansas Infantry Regiment in the Confederate Army. James Yell's was transferred to the Confederate States Army in the summer of 1861, and James left the service and moved to Texas.
