Context paragraphs:
Tudor conquest of Ireland: The Tudor conquest (or reconquest) of Ireland took place under the Tudor dynasty, which held the Kingdom of England during the 16th century.  Following a failed rebellion against the crown by Silken Thomas, the Earl of Kildare, in the 1530s, Henry VIII was declared King of Ireland by statute of the Parliament of Ireland, with the aim of restoring such central authority as had been lost throughout the country during the previous two centuries.

Battle of Bosworth Field: The Battle of Bosworth Field (or Battle of Bosworth) was the last significant battle of the Wars of the Roses, the civil war between the Houses of Lancaster and York that raged across England in the latter half of the 15th century.  Fought on 22 August 1485, the battle was won by the Lancastrians.  Their leader Henry Tudor, Earl of Richmond, by his victory became the first English monarch of the Tudor dynasty.  His opponent, Richard III, the last king of the House of York, was killed in the battle.  Historians consider Bosworth Field to mark the end of the Plantagenet dynasty, making it a defining moment of English and Welsh history.

John of Islay, Earl of Ross: John of Islay (or John MacDonald) (1434–1503) was a late medieval Scottish magnate.  He was Earl of Ross and the 4th Lord of the Isles as well as being "Mac Domhnaill", chief of Clan Donald.  John would however prove to be the last of the Lords of the Isles, overmighty subjects of the Stewart Kings of Scotland and virtual kings in their own right in the Western Isles.  His struggle for power with King James III of Scotland ended in humiliation, following which his illegitimate son Angus Óg rebelled against his rule.  In a bitter civil war, John's fleet of galleys met those of Angus sometime in the early 1480s off the coast of Mull at the Battle of Bloody Bay, in which John's cause was defeated.  After Bloody Bay he became an inconsequential figure; and Angus continued to dominate the affairs of Clan Donald up until his murder in 1490.  In 1493 James IV brought the Lordship of the Isles to an end.  John died unlamented in 1503, having witnessed the almost complete destruction of his family inheritance.

Tudor Poor Laws: The Tudor Poor Laws were the laws regarding poor relief in the Kingdom of England around the time of the Tudor period (1485–1603).  The Tudor Poor Laws ended with the passing of the Elizabethan Poor Law in 1601, two years before the end of the Tudor dynasty, a piece of legislation which codified the previous Tudor legislation.

Tudor City: Tudor City is an apartment complex located on the southern edge of Turtle Bay on the East Side of Manhattan in New York City, near Turtle Bay's border with Kips Bay.  Construction commenced in 1927, making the building the first residential skyscraper complex in the world.  It is bordered by 40th Street to the south, First Avenue to the east, Second Avenue to the west, and 43rd Street to the north.  Tudor City takes its name from England's Tudor dynasty, which ruled from 1485 to 1603 and included King Henry VIII and Queen Elizabeth I.

Clan Heron: The Clan Heron was a border raiding clan.  They made a living by rustling cattle along the Anglo-Scottish border.

Tudor architecture: The Tudor architectural style is the final development of Medieval architecture in England, during the Tudor period (1485–1603) and even beyond, and also the tentative introduction of Renaissance architecture to England.  It is generally not used to refer to the whole period of the Tudor dynasty (1485-1603), but in prestige buildings to the period roughly between 1500 and 1560.  It followed the Late Gothic Perpendicular style and was superseded by Elizabethan architecture from about 1560 in domestic building of any pretensions to fashion.  In the much more slow-moving styles of vernacular architecture "Tudor" has become a designation for styles like half-timbering that characterise the few buildings surviving from before 1485 and others from the Stuart period.  In this form the Tudor style long retained its hold on English taste.  Nevertheless, 'Tudor style' is an awkward style-designation, with its implied suggestions of continuity through the period of the Tudor dynasty and the misleading impression that there was a style break at the accession of Stuart James I in 1603.

Border Reivers: Border reivers were raiders along the Anglo-Scottish border from the late 13th century to the beginning of the 17th century.  Their ranks consisted of both Scottish and English families, and they raided the entire Border country without regard to their victims' nationality.  Their heyday was perhaps in the last hundred years of their existence, during the time of the Stewart Kings in Scotland and the Tudor dynasty in England.

Owen Tudor: Sir Owen Tudor (Welsh: "Owain ap Maredudd ap Tudur" , 1400 – 2 February 1461) was a Welsh courtier and the second husband of Catherine of Valois (1401–1437), Henry V's widow.  He was the grandfather of Henry VII, founder of the Tudor dynasty.  Owen was a descendant of a prominent family from Penmynydd on the Isle of Anglesey, which traces its lineage back to Ednyfed Fychan (d. 1246), a Welsh official and seneschal to the Kingdom of Gwynedd.  Tudor's grandfather, Tudur ap Goronwy, married Margaret, daughter of Thomas ap Llywelyn ab Owain of Cardiganshire, the last male of the princely house of Deheubarth.  Margaret's elder sister married Gruffudd Fychan of Glyndyfrdwy, whose son was Owain Glyndŵr.  Owen's father, Maredudd ap Tudur, and his uncles were prominent in Owain Glyndŵr's revolt against English rule, the Glyndŵr Rising.

HMS Tudor (P326): HMS "Tudor" was a British submarine of the third group of the T class.  She was built as "P326" at Devonport Dockyard, and launched on 23 September 1942.  So far she has been the only ship of the Royal Navy to bear the name "Tudor", after the Tudor period or Tudor dynasty.
