Question: In what year did the Union of the Crowns expand the personal union to include Scotland which was the year when Elizabeth I,Queen of England and Ireland, died?

Margaret Tudor (28 November 1489 – 18 October 1541) was Queen of Scots from 1503 until 1513 by marriage to James IV of Scotland and then, after her husband died fighting the English, she became regent for their son James V of Scotland.  She was born at Westminster Palace as the oldest daughter of Henry VII of England and Elizabeth of York, and granddaughter of Margaret Beaufort, Edward IV of England and Queen Elizabeth Woodville.  Margaret Tudor had several pregnancies, but most of her children died young or were stillborn.  As queen dowager she married Archibald Douglas, 6th Earl of Angus.  Through her first and second marriages, respectively, Margaret was the grandmother of both Mary, Queen of Scots, and Mary's second husband, Lord Darnley.  Margaret's marriage to James IV foreshadowed the Union of the Crowns – their great-grandson, James VI and I, was the first to be monarch of both Scotland and England. <SEP>  Sometimes called The Virgin Queen, Gloriana or Good Queen Bess, Elizabeth was the last monarch of the House of Tudor. Elizabeth I (7 September 1533 – 24 March 1603) was Queen of England and Ireland from 17 November 1558 until her death. <SEP> Elizabeth of Bosnia (  1339  – January 1387) was queen consort and later regent of Hungary and Croatia, as well as queen consort of Poland.  Daughter of Ban Stephen II of Bosnia, Elizabeth married King Louis I of Hungary in 1353.  In 1370, she gave birth to a long-anticipated heir, Catherine, and became Queen of Poland when Louis succeeded his uncle, Casimir III.  The royal couple had two more daughters, Mary and Hedwig, but Catherine died in 1378.  Initially a powerless consort with no substantial influence, Elizabeth then started surrounding herself with noblemen loyal to her, led by her favourite, Nicholas I Garai.  When Louis died in 1382, Mary ascended to the throne of Hungary with Elizabeth as regent.  Unable to preserve the personal union of Hungary and Poland, the queen dowager secured the Polish throne for her youngest daughter, Hedwig. <SEP> A monarchical system of government existed in Ireland from ancient times until, for what became the Republic of Ireland, the mid-twentieth century.  Northern Ireland, as part of the United Kingdom, remains under a monarchical system of government.  The Gaelic kingdoms of Ireland ended with the Norman invasion of Ireland, when the kingdom became a fief of the Holy See under the Lordship of the King of England.  This lasted until the Parliament of Ireland conferred the crown of Ireland upon King Henry VIII of England during the English Reformation.  The Union of the Crowns in 1603 expanded the personal union to include Scotland.  The monarch of England held the crowns of England and Ireland in a personal union.  The personal union between England and Scotland became a political union with the enactments of the Acts of Union 1707, which created the Kingdom of Great Britain.  The crowns of Great Britain and Ireland remained in personal union until it was ended by the Acts of Union 1800, which united Ireland and Great Britain into the United Kingdom of Great Britain and Ireland from January 1801 until December 1922.
