Question: When the first war between the supporters of Maria Christina and Carlos of Borbón begin? Passage 1:For the 2008 Isle of Man TT Races, following the deaths of a race competitor and two spectators at the 26th Milestone during the 2007 Senior TT a number of changes occurred in spectator safety and road widening occurred at Braddan Bridge and a new link road and mini-roundabout at Governor's Bridge. The race organisation changed with the Manx Motor Cycle Club (MMCC) replaced by ACU Events Ltd a subsidiary of the Auto-Cycle Union (ACU). A contract for the official course vehicles was awarded to Audi in a 3-year deal to celebrate the win by the pre-war Audi satellite company DKW by Ewald Kluge in the 1938 Isle of Man TT Races. A further contract was awarded to Yamaha UK to provide motor-cycles and support for the TT Travelling Marshalls. The Isle of Man TT competitor Martin Finnegan was killed while racing at the Tandragee 100 Races on 3 May 2008 and this was followed by the former Isle of Man TT and Manx Grand Prix winner Robert Dunlop who died in an accident on 16 May 2008 at Mather's Cross during practice for the 2008 North West 200 Races.
 Passage 2:The Basque Country was one of the main sites of battles during the First Carlist War, a civil war between supporters of the Spanish regent Maria Christina, known as liberals, and those of the late king's brother Carlos of Borbón, known as Carlists. The Carlists were particularly focused on capturing Bilbao, a liberal and economic bastion in northern Spain. The Carlist general Tomás de Zumalacárregui tried to take the city during the Siege of Bilbao of 1835, but he was wounded during a battle near Begoña and died some time after in the town of Zegama. The next year, the city resisted a second siege during which the liberal general Baldomero Espartero defeated the Carlists in the Battle of Luchana. The city was untouched by the Second Carlist War, which took place mostly in Catalonia, but was again an important scenario during the Third Carlist War; in April 1874 the city suffered a third siege which lasted two months.
 Passage 3:Jowett was born in Peckham, Kent, and grew up in Camberwell, the third of nine children. His father was a furrier originally from a Yorkshire family that, for three generations, had been supporters of the Evangelical movement in the Church of England, and an author of a metrical translation of the Old Testament Psalms. His mother was a Langhorne, related to John Langhorne, the poet and translator of Plutarch. At twelve, Jowett was placed on the foundation of St Paul's School (then in St Paul's Churchyard) where he soon gained a reputation as a precocious classical scholar. Aged eighteen he was awarded an open scholarship to Balliol College, Oxford, where he remained for the rest of his life. He went up in 1836, and was quickly recognized as one of the leading Oxford dons of his generation, made a Fellow while still an undergraduate in 1838; he graduated with first-class honours in 1839. This was at the height of the Oxford Tractarian movement: through the friendship of W. G. Ward he was drawn for a time in the direction of High Anglicanism; but a stronger and more lasting influence was that of the Arnold school, represented by A. P. Stanley. The controversy caused Jowett to withdraw from High Table at college to lodgings in Broad Street.
