Question:
Gaelic Ireland (Irish: Eire Ghaidhealach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time. For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry.
For most of the Gaelic period, dwellings and farm buildings were circular with conical thatched roofs (see roundhouse). Square and rectangle-shaped buildings gradually became more common, and by the 14th or 15th century they had replaced round buildings completely. In some areas, buildings were made mostly of stone. In others, they were built of timber, wattle and daub, or a mix of materials. Most ancient and early medieval stone buildings were of dry stone construction. Some buildings would have had glass windows. Among the wealthy, it was common for women to have their own 'apartment' called a grianan (anglicized "greenan") in the sunniest part of the homestead. The dwellings of freemen and their families were often surrounded by a circular rampart called a "ringfort". There are two main kinds of ringfort. The rath is an earthen ringfort, averaging 30m diameter, with a dry outside ditch. The cathair or caiseal is a stone ringfort. The ringfort would typically have enclosed the family home, small farm buildings or workshops, and animal pens. Most date to the period 500-1000 CE and there is evidence of large-scale ringfort desertion at the end of the first millennium. The remains of between 30,000 and 40,000 lasted into the 19th century to be mapped by Ordnance Survey Ireland. Another kind of native dwelling was the crannog, which were roundhouses built on artificial islands in lakes. There were very few nucleated settlements in Gaelic areas. However, after the 5th century some monasteries became the heart of small "monastic towns". By the 10th century the Norse-Gaelic ports of Dublin, Wexford, Cork and Limerick had grown into substantial settlements. It was at this time, perhaps as a response to Viking raids, that many of the Irish round towers were built. In the fifty years before the Norman invasion, the term "castle" (Old Irish: caistel/caislen) appears in Gaelic writings, although there are no surviving examples of pre-Norman castles. After the invasion, the Normans built motte-and-bailey castles in the areas they occupied, some of which were converted from ringforts. By 1300 "some mottes, especially in frontier areas, had almost certainly been built by the Gaelic Irish in imitation". The Normans gradually replaced wooden motte-and-baileys with stone castles and tower houses. Tower houses are free-standing multi-storey stone towers usually surrounded by a wall (see bawn) and ancillary buildings. Gaelic families had begun to build their own tower houses by the 15th century. As many as 7000 may have been built, but they were rare in areas with little Norman settlement or contact. They are concentrated in counties Limerick and Clare but are lacking in Ulster, except the area around Strangford Lough. In Gaelic law, a 'sanctuary' called a maighin digona surrounded each person's dwelling. The maighin digona's size varied according to the owner's rank. In the case of a boaire it stretched as far as he, while sitting at his house, could cast a cnairsech (variously described as a spear or sledgehammer). The owner of a maighin digona could offer its protection to someone fleeing from pursuers, who would then have to bring that person to justice by lawful means.

Question:
Aaron Benjamin Sorkin (born June 9, 1961) is an American screenwriter, director, producer, and playwright. His works include the Broadway plays A Few Good Men and The Farnsworth Invention; the television series Sports Night, The West Wing, Studio 60 on the Sunset Strip, and The Newsroom; and the films A Few Good Men, The American President, Charlie Wilson's War, Moneyball, and Steve Jobs. For writing The Social Network, he won the Oscar for Best Adapted Screenplay, among other awards. He made his feature directorial debut in 2017 with Molly's Game, which he also wrote.
Sorkin was born in Manhattan, New York City, to a Jewish family, and was raised in the New York suburb of Scarsdale. His mother was a schoolteacher and his father a copyright lawyer who had fought in WWII and put himself through college on the G.I. Bill; both his older sister and brother went on to become lawyers. His paternal grandfather was one of the founders of the International Ladies' Garment Workers' Union (ILGWU). Sorkin took an early interest in acting. Before he reached his teenage years, his parents were taking him to the theatre to see shows such as Who's Afraid of Virginia Woolf? and That Championship Season. Sorkin attended Scarsdale High School where he became involved in the drama and theatre club. In eighth grade he played General Bullmoose in the musical Li'l Abner. At Scarsdale High, he served as vice president of the drama club in his junior and senior years and graduated in 1979. In 1979, Sorkin attended Syracuse University. In his freshman year he failed a class that was a core requirement. It was a devastating setback because he wanted to be an actor, and the drama department did not allow students to take the stage until they completed all the core freshman classes. Determined to do better, he returned in his sophomore year, and graduated in 1983. Recalling the influence on him at college of drama teacher Arthur Storch, Sorkin recalled, after Storch's death in March 2013, that "Arthur's reputation as a director, and as a disciple of Lee Strasberg, was a big reason why a lot of us went to S.U. ... 'You have the capacity to be so much better than you are', he started saying to me in September of my senior year. He was still saying it in May. On the last day of classes, he said it again, and I said, 'How?', and he answered, 'Dare to fail'. I've been coming through on his admonition ever since".
