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.

Did he take over the Sinhalese people?

Tambapanni was originally inhabited and governed by Yakkhas, having their capital at Sirisavatthu

Cary Grant (born Archibald Alec Leach; January 18, 1904 - November 29, 1986) was an English-American actor, known as one of classic Hollywood's definitive leading men. He began a career in Hollywood in the early 1930s, and became known for his transatlantic accent, debonair demeanor, and light-hearted approach to acting and sense of comic timing. He became an American citizen in 1942. Born in Horfield, Bristol, Grant became attracted to theatre at a young age, and began performing with a troupe known as "The Penders" from the age of six.
Stirling refers to Grant as "one of the shrewdest businessmen ever to operate in Hollywood". His long-term friendship with Howard Hughes from the 1930s onward saw him invited into the most glamorous circles in Hollywood and their lavish parties. Biographers Morecambe and Stirling state that Hughes played a major role in the development of Grant's business interests, so that by 1939, he was "already an astute operator with various commercial interests". Scott also played a role, encouraging Grant to invest his money in shares, making him a wealthy man by the end of the 1930s. In the 1940s, Grant and Barbara Hutton invested heavily in real estate development in Acapulco at a time when it was little more than a fishing village, and teamed with Richard Widmark, Roy Rogers, and Red Skelton to buy a hotel there. Behind his business interests was a particularly intelligent mind, to the point that his friend David Niven once said: "Before computers went into general release, Cary had one in his brain". Film critic David Thomson believes that Grant's intelligence came across on screen, and stated that "no one else looked so good and so intelligent at the same time". After Grant retired from the screen, he became more active in business. He accepted a position on the board of directors at Faberge. This position was not honorary, as some had assumed; Grant regularly attended meetings and travelled internationally to support them. His pay was modest in comparison to the millions of his film career, a salary of a reported $15,000 a year. Such was Grant's influence on the company that George Barrie once claimed that Grant had played a role in the growth of the firm to annual revenues of about $50 million in 1968, a growth of nearly 80% since the inaugural year in 1964. The position also permitted use of a private plane, which Grant could use to fly to see his daughter wherever her mother, Dyan Cannon, was working. In 1975, Grant was an appointed director of MGM. In 1980, he sat on the board of MGM Films and MGM Grand Hotels following the division of the parent company. He played an active role in the promotion of MGM Grand Hotel in Las Vegas when opened in 1973, and he continued to promote the city throughout the 1970s. When Allan Warren met Grant for a photo shoot that year he noticed how tired Grant looked, and his "slightly melancholic air". Grant later joined the boards of Hollywood Park, the Academy of Magical Arts (The Magic Castle, Hollywood, California), and Western Airlines (acquired by Delta Air Lines in 1987).

What are the business interests on Cary?
Hughes played a major role in the development of Grant's business interests, so that by 1939, he was "already an astute operator with various commercial interests".
