Question: When did the state that the most successful artist from this season of American Idol is from, become a part of the U.S.?

full_context: Document 1: American Idol: Both finalists found success after the show, but Aiken out-performed Studdard's coronation song "Flying Without Wings" with his single release from the show "This Is the Night", as well as in their subsequent album releases. The fourth-place finisher Josh Gracin also enjoyed some success as a country singer.
Document 2: Raleigh, North Carolina: Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. The city was originally laid out in a grid pattern with the North Carolina State Capitol in Union Square at the center. In the United States Civil War the city was spared from any significant battle, only falling in the closing days of the war, though it did not escape the economic hardships that plagued the rest of the American South during the Reconstruction Era. The twentieth century saw the opening of the Research Triangle Park in 1959, and with the jobs it created the region and city saw a large influx of population, making it one of the fastest growing communities in the United States by the early 21st century.
Document 3: American Idol: Despite being eliminated earlier in the season, Chris Daughtry (as lead of the band Daughtry) became the most successful recording artist from this season. Other contestants, such as Hicks, McPhee, Bucky Covington, Mandisa, Kellie Pickler, and Elliott Yamin have had varying levels of success.
Document 4: American Idol: As one of the most successful shows on U.S. television history, American Idol has a strong impact not just on television, but also in the wider world of entertainment. It helped create a number of highly successful recording artists, such as Kelly Clarkson, Daughtry and Carrie Underwood, as well as others of varying notability.
Document 5: North Carolina: While slaveholding was slightly less concentrated than in some Southern states, according to the 1860 census, more than 330,000 people, or 33% of the population of 992,622, were enslaved African Americans. They lived and worked chiefly on plantations in the eastern Tidewater. In addition, 30,463 free people of color lived in the state. They were also concentrated in the eastern coastal plain, especially at port cities such as Wilmington and New Bern, where a variety of jobs were available. Free African Americans were allowed to vote until 1835, when the state revoked their suffrage in restrictions following the slave rebellion of 1831 led by Nat Turner. Southern slave codes criminalized willful killing of a slave in most cases.
Document 6: American Idol: In what was to become a tradition, Clarkson performed the coronation song during the finale, and released the song immediately after the season ended. The single, "A Moment Like This", went on to break a 38-year-old record held by The Beatles for the biggest leap to number one on the Billboard Hot 100. Guarini did not release any song immediately after the show and remains the only runner-up not to do so. Both Clarkson and Guarini made a musical film, From Justin to Kelly, which was released in 2003 but was widely panned. Clarkson has since become the most successful Idol contestant internationally, with worldwide album sales of more than 23 million.
Document 7: American Idol: American Idol is an American singing competition television series created by Simon Fuller, produced by FremantleMedia North America and 19 Entertainment, and distributed by FremantleMedia North America. It began airing on Fox on June 11, 2002, and ended its first - run on April 7, 2016. On March 11, 2018, the show will make its debut on ABC. It started off as an addition to the Idols format based on the British series Pop Idol, and became one of the most successful shows in the history of American television. The concept of the series involves discovering recording stars from unsigned singing talents, with the winner determined by the viewers in America through telephones, Internet, and SMS text voting. Winners chosen by viewers in its fifteen seasons were Kelly Clarkson, Ruben Studdard, Fantasia, Carrie Underwood, Taylor Hicks, Jordin Sparks, David Cook, Kris Allen, Lee DeWyze, Scotty McCreery, Phillip Phillips, Candice Glover, Caleb Johnson, Nick Fradiani, and Trent Harmon.
Document 8: American Idol: Theories given for the success of Southerners on Idol have been: more versatility with musical genres, as the Southern U.S. is home to several music genre scenes; not having as many opportunities to break into the pop music business; text-voting due to the South having the highest percentage of cell-phone only households; and the strong heritage of music and singing, which is notable in the Bible Belt, where it is in church that many people get their start in public singing. Others also suggest that the Southern character of these contestants appeal to the South, as well as local pride. According to season five winner Taylor Hicks, who is from the state of Alabama, "People in the South have a lot of pride ... So, they're adamant about supporting the contestants who do well from their state or region."
Document 9: American Idol: The show itself is popular in the Southern United States, with households in the Southeastern United States 10% more likely to watch American Idol during the eighth season in 2009, and those in the East Central region, such as Kentucky, were 16 percent more likely to tune into the series. Data from Nielsen SoundScan, a music-sales tracking service, showed that of the 47 million CDs sold by Idol contestants through January 2010, 85 percent were by contestants with ties to the American South.
Document 10: American Idol: Ruben Studdard emerged as the winner, beating Clay Aiken by a small margin. Out of a total of 24 million votes, Studdard finished just 134,000 votes ahead of Aiken. This slim margin of victory was controversial due to the large number of calls that failed to get through. In an interview prior to season five, executive producer Nigel Lythgoe indicated that Aiken had led the fan voting from the wildcard week onward until the finale.
Document 11: American Idol: Since the show's inception in 2002, ten of the fourteen Idol winners, including its first five, have come from the Southern United States. A large number of other notable finalists during the series' run have also hailed from the American South, including Clay Aiken, Kellie Pickler, and Chris Daughtry, who are all from North Carolina. In 2012, an analysis of the 131 contestants who have appeared in the finals of all seasons of the show up to that point found that 48% have some connection to the Southern United States.
Document 12: North Carolina: On November 21, 1789, North Carolina became the twelfth state to ratify the Constitution. In 1840, it completed the state capitol building in Raleigh, still standing today. Most of North Carolina's slave owners and large plantations were located in the eastern portion of the state. Although North Carolina's plantation system was smaller and less cohesive than that of Virginia, Georgia, or South Carolina, significant numbers of planters were concentrated in the counties around the port cities of Wilmington and Edenton, as well as suburban planters around the cities of Raleigh, Charlotte, and Durham in the Piedmont. Planters owning large estates wielded significant political and socio - economic power in antebellum North Carolina, which was a slave society. They placed their interests above those of the generally non-slave - holding ``yeoman ''farmers of western North Carolina. In mid-century, the state's rural and commercial areas were connected by the construction of a 129 - mile (208 km) wooden plank road, known as a`` farmer's railroad'', from Fayetteville in the east to Bethania (northwest of Winston - Salem).
Document 13: American Idol: Chris Daughtry's performance of Fuel's "Hemorrhage (In My Hands)" on the show was widely praised and led to an invitation to join the band as Fuel's new lead singer, an invitation he declined. His performance of Live's version of "I Walk the Line" was well received by the judges but later criticized in some quarters for not crediting the arrangement to Live. He was eliminated at the top four in a shocking result.
Document 14: North Carolina: As in the rest of the former Confederacy, North Carolina had become a one-party state, dominated by the Democratic Party. Impoverished by the Civil War, the state continued with an economy based on tobacco, cotton and agriculture. Towns and cities remained few in the east. A major industrial base emerged in the late 19th century in the western counties of the Piedmont, based on cotton mills established at the fall line. Railroads were built to connect the new industrializing cities. The state was the site of the first successful controlled, powered and sustained heavier-than-air flight, by the Wright brothers, near Kitty Hawk on December 17, 1903. In the first half of the 20th century, many African Americans left the state to go North for better opportunities, in the Great Migration. Their departure changed the demographic characteristics of many areas.
