The Valois House of Anjou, or the Younger House of Anjou, was a noble French family, deriving from the royal family, the House of Valois. They were monarchs of Naples, as well as various other territories.

The house began in the 1350s, when king John II of France, of the House of Valois line of Capetians, came to power. His paternal grandmother, Margaret, Countess of Anjou and Maine, had been a princess of the Capetian House of Anjou or Elder Angevin Dynasty. She was the eldest daughter of king Charles II of Naples and gave the county, and then duchy of Anjou to the second son of king John II of France, Louis.

Within a couple of decades, Queen Joan I of Naples, also of the senior Angevin line, realized that she would remain childless. Although there were extant heirs of the senior branch, for example, the Anjou-Durazzo cadet line, she decided to adopt Louis as her final heir.

Thus, in addition to the struggle of the Angevins with the Aragonese in Southern Italy, the two Angevin lines, senior and junior, now began to contest with each other for the possession of the Kingdom of Naples.

Margaret of Anjou (French: Marguerite d'Anjou) (23 March 1430 – 25 August 1482) was the wife of King Henry VI of England. As such, she was Queen consort of England from 1445 to 1461 and again from 1470 to 1471. She also claimed to be Queen consort of France from 1445 to 1453. Born in the Duchy of Lorraine, into the House of Valois-Anjou, Margaret was the second eldest daughter of René I of Naples and Isabella, Duchess of Lorraine.

She was one of the principal figures in the series of dynastic civil wars known as the Wars of the Roses and at times personally led the Lancastrian faction. Due to her husband's frequent bouts of insanity, Margaret ruled the kingdom in his place. It was she who called for a Great Council in May 1455 that excluded the Yorkist faction headed by Richard, Duke of York, and thus provided the spark that ignited a civil conflict that lasted for over thirty years, decimated the old nobility of England, and caused the deaths of thousands of men, including her only son Edward of Westminster, Prince of Wales, at the Battle of Tewkesbury in 1471.

Jacob Abbott (November 14, 1803 – October 31, 1879) was an American writer of children's books.

Abbott was born at Hallowell, Maine to Jacob and Betsey Abbott. He graduated from Bowdoin College in 1820; studied at Andover Theological Seminary in 1821, 1822, and 1824; was tutor in 1824-1825, and from 1825 to 1829 was professor of mathematics and natural philosophy at Amherst College; was licensed to preach by the Hampshire Association in 1826; founded the Mount Vernon School for Young Ladies in Boston in 1829, and was principal of it in 1829-1833; was pastor of Eliot Congregational Church (which he founded), at Roxbury, Massachusetts in 1834-1835; and was, with his brothers, a founder, and in 1843-1851 a principal of Abbott's Institute, and in 1845-1848 of the Mount Vernon School for Boys, in New York City.

He was a prolific author, writing juvenile fiction, brief histories, biographies, religious books for the general reader, and a few works in popular science. He died in Farmington, Maine, where he had spent part of his time after 1839, and where his brother, Samuel Phillips Abbott, founded the Abbott School.
