Question:
The Blues Brothers is a 1980 American musical comedy film directed by John Landis. It stars John Belushi and Dan Aykroyd as "Joliet" Jake and Elwood Blues, characters developed from "The Blues Brothers" musical sketch on the NBC variety series Saturday Night Live. The film's screenplay was written by Aykroyd and Landis. It features musical numbers by rhythm and blues (R&B), soul, and blues singers James Brown, Cab Calloway, Aretha Franklin, Ray Charles, and John Lee Hooker.
Much of the film was shot on location in and around Chicago between July and October 1979, including Wauconda, Illinois, where the car crashes into the side of Route 12. Made with the cooperation of Mayor Jane M. Byrne, it is credited for putting Chicago on the map as a venue for filmmaking. Nearly 200 movies have been filmed in Chicago. "Chicago is one of the stars of the movie. We wrote it as a tribute," Dan Aykroyd told the Chicago Sun-Times in an article written to mark the film's 25th-anniversary DVD release.  The first traffic stop was in Park Ridge, Illinois. The shopping mall car chase was filmed in the real, albeit shuttered, Dixie Square Mall, in Harvey, Illinois. The bridge jump was filmed on an actual drawbridge, the 95th Street bridge over the Calumet River, on the southeast side of Chicago. The main entrance to Wrigley Field (and its sign reading "Save lives. Drive safely, prevent fires.") makes a brief appearance when the "Illinois Nazis" visit it after Elwood falsely registers the ballpark's location, 1060 West Addison, as his home address on his driver's license. (Elwood's Illinois driver's license number is an almost-valid encoded number, with Dan Aykroyd's own birth date embedded.) Jake's final confrontation with his girlfriend was filmed in a replica of a section of the abandoned Chicago freight tunnel system. The other chase scenes included lower Wacker Drive, Lake Street, and Richard J. Daley Center.  In the final car chase scene, the production actually dropped a Ford Pinto, representing the one driven by the "Illinois Nazis", from a helicopter at an altitude of about 1,200 feet--and had to gain a Special Airworthiness Certificate from the Federal Aviation Administration to do it. The FAA was concerned that the car could prove too aerodynamic in a high-altitude drop, and pose a threat to nearby buildings. The shot leading up to the car drop, where the "Illinois Nazis" drive off a freeway ramp, was shot in Milwaukee, Wisconsin, near the Hoan Bridge on Interstate 794. The Lake Freeway (North) was a planned but not completed six-lane freeway, and I-794 contained an unfinished ramp off which the Nazis drove. Several Milwaukee skyscrapers are visible in the background as the Bluesmobile flips over, notably the U.S. Bank Center.  The Palace Hotel Ballroom, where the band performs its climactic concert, was at the time of filming a country club, but later became the South Shore Cultural Center, named after the Chicago neighborhood where it is located. The interior concert scenes were filmed in the Hollywood Palladium.  The filming in downtown Chicago was conducted on Sundays during the summer of 1979, and much of the downtown was cordoned off from the public. Costs for filming the largest scene in the city's history totaled $3.5 million. Permission was given after Belushi and Aykroyd offered to donate $50,000 to charity after filming. Although the Bluesmobile was allowed to be driven through the Daley Center lobby, special breakaway panes were temporarily substituted for the normal glass in the building. The speeding car caused $7,650 in damage to 35 granite paver stones and a bronze air grill in the building. Interior shots of the elevator, staircase, and assessor's office were all recreated in a film set for filming.

Question:
The British Band was a mixed-nation group of Native Americans commanded by the Sauk leader Black Hawk, which fought against Illinois and Michigan Territory militias during the 1832 Black Hawk War. The band was composed of about 1,500 men, women, and children from the Sauk, Meskwaki, Fox, Kickapoo, Potawatomi, Ho-Chunk, and Ottawa nations; about 500 of that number were warriors. Black Hawk had an alliance with the British that dated from the War of 1812, giving them their colloquial name. The band crossed the Mississippi River from Iowa into Illinois in an attempt to reclaim their homeland and in violation of several treaties.
Sauk warrior Black Hawk, the leader of a band of Sauks near Rock Island at Saukenuk, was always in opposition to ceding Native American lands to white settlers and their governments. Black Hawk supported the invalidity of the Treaty of St. Louis (1804) of both the Sauk and Fox nations negotiated with the then Indiana Territory Governor William Henry Harrison. The treaty ceded territory, including Black Hawk's birthplace Saukenuk, to the United States. The Sauk are a consensus decision making society. Their representatives exceeded the authorization of merely taking under consideration what terms the United States government might put forth, bring them back to reach a consensus and then return with their treaty terms. The lack of the tribe discussing the treaty prior to being made official made it invalid by Black Hawk and other members of the tribe. The representatives never had the tribal authorization to unilaterally cede its lands.  During the War of 1812 between the United Kingdom and the United States, Colonel Robert Dickson, an English fur trader, amassed a sizable force of Native Americans at Green Bay to assist the British in operations around the Great Lakes. Most of the warriors Dickson assembled were from the Potawatomi, Ho-Chunk, Kickapoo and Ottawa tribes. Dickson bestowed the rank of brevet Brigadier General on Black Hawk. He was given command of all Native Americans gathered at Green Bay, including the 200 Sauk warriors under Black Hawk's control. Black Hawk was then presented with a silk flag, a medal, and a written certificate of good behavior and alliance with the British. The certificate would be found 20 years later, after the Battle of Bad Axe, carefully preserved along with a flag similar to the one Dickson gave to Black Hawk.  During the 1812 war, Black Hawk and his warriors fought in several engagements with Henry Procter on the borders of Lake Erie. He returned home to Saukenuk to find his rival Keokuk had become the tribe's war chief. After the war ended, Black Hawk signed a peace treaty in May 1816 that re-affirmed the treaty of 1804, a provision Black Hawk later protested ignorance of.
