Answer the question at the end by quoting:

The Sinhalese (Sinhala: siNhl jaatiy Sinhala Jathiya, also known as Hela) are an Indo-Aryan-speaking ethnic group native to the island of Sri Lanka. They constitute about 75% of the Sri Lankan population and number greater than 16.2 million. The Sinhalese identity is based on language, historical heritage and religion. The Sinhalese people speak the Sinhalese language, an Indo-Aryan language, and are predominantly Theravada Buddhists, although a small percentage of Sinhalese follow branches of Christianity.
Prince Vijaya and his 700 followers left Supparaka, landed on the island at a site believed to be in the district of Chilaw, near modern-day Mannar, and founded the Kingdom of Tambapanni. It is recorded the Vijaya made his landing on the day of Buddha's death. Vijaya claimed Tambapanni his capital and soon the whole island come under this name. Tambapanni was originally inhabited and governed by Yakkhas, having their capital at Sirisavatthu and their queen Kuveni. According to the Samyutta Commentary, Tambapanni was one hundred leagues in extent.  After landing in Tambapanni Vijaya met Kuveni the queen of the Yakkhas, who was disguised as a beautiful woman but was really a 'yakkini' (devil) named Sesapathi.  At the end of his reign, Vijaya, having trouble choosing a successor, sent a letter to the city of his ancestors, Sinhapura, in order to invite his brother Sumitta to take over the throne. However, Vijaya had died before the letter had reached its destination, so the elected minister of the people Upatissa, the Chief government minister or prime minister and leading chief among the Sinhalese became regent and acted as regent for a year. After his coronation, which was held in the Kingdom of Tambapanni, he left it, building another one, bearing his own name. While he was king, Upatissa established the new capital Upatissa, in which the kingdom was moved to from the Kingdom of Tambapanni. When Vijaya's letter arrived, Sumitta had already succeeded his father as king of his country, and so he sent his son Panduvasdeva to rule Upatissa Nuwara.  Upatissa Nuwara was seven or eight miles further north of the Kingdom of Tambapanni. It was named after the regent king Upatissa, who was the prime minister of Vijaya, and was founded in 505 BC after the death of Vijaya and the end of the Kingdom of Tambapanni.

Is this were the Sinhalese live today?

after the death of Vijaya and the end of the Kingdom of Tambapanni.

IN: Richard was born on 2 October 1452 at Fotheringhay Castle, the twelfth of thirteen children of Richard Plantagenet, 3rd Duke of York and Cecily Neville at the beginning of what has traditionally been labelled the "Wars of the Roses", a period of "three or four decades of political instability and periodic open civil war in the second half of the fifteenth century", between supporters of Richard's father (a potential claimant to the throne of King Henry VI from birth)--"Yorkists"--in opposition to the regime of Henry VI and his wife, Margaret of Anjou, and those loyal to the crown ("Lancastrians"). When his father and the Nevilles were forced to flee to Ludlow in 1459, Richard and his older brother, George (later Duke of Clarence), were placed in the custody of the Duchess of Buckingham, and the Archbishop of Canterbury. When his father and elder brother Edmund, Earl of Rutland, were killed at the Battle of Wakefield on 30 December 1460, Richard, who was eight years old, and George were sent by his mother, the Duchess of York, to the Low Countries. They returned to England following the defeat of the Lancastrians at the Battle of Towton and participated in the coronation of Richard's eldest brother as King Edward IV in June 1461.

In 1485, following his death in battle against Henry Tudor at Bosworth Field, Richard III's body was buried in Greyfriars Church in Leicester.  Following the discoveries of Richard's remains in 2012, it was decided that they should be reburied at Leicester Cathedral, despite feelings in some quarters that he should have been reburied in York Minster. His remains were carried in procession to the cathedral on 22 March 2015, and reburied on 26 March 2015 at a religious re-burial service at which both the Right Reverend Tim Stevens, the Bishop of Leicester, and the Most Reverend Justin Welby, the Archbishop of Canterbury, officiated. The British Royal Family was represented by the Duke and Duchess of Gloucester and the Countess of Wessex. The actor Benedict Cumberbatch, who is a distant relation of the king and later portrayed him in The Hollow Crown television series, read a poem by Poet Laureate Carol Ann Duffy.  His cathedral tomb was designed by the architects van Heyningen and Haward. The tombstone is deeply incised with a cross, and consists of a rectangular block of white Swaledale fossil stone, quarried in North Yorkshire. It sits on a low plinth made of dark Kilkenny marble, incised with Richard's name, dates and motto (Loyaulte me lie - loyalty binds me). The plinth also carries his coat of arms in pietra dura. The remains of Richard III are in a lead-lined coffin, inside an outer English oak coffin crafted by Michael Ibsen, a direct descendant of Richard's sister Anne of York, and laid in a brick-lined vault below the floor, and below the plinth and tombstone. The original 2010 raised tomb design had been proposed by Langley`s "Looking For Richard Project" and fully funded by members of the Richard III Society. The proposal was publicly launched by the Society on 13 February 2013 but rejected by Leicester Cathedral in favour of a memorial slab. However, following a public outcry, the Cathedral changed its position and on 18 July 2013 announced its agreement to give King Richard III a raised tomb monument.

Was this a big deal?
