In government, unicameralism (Latin uni, one + camera, chamber) is the practice of having one legislative or parliamentary chamber. Thus, a unicameral parliament or unicameral legislature is a legislature which consists of one chamber or house. Some countries with unicameral legislatures are often small and homogeneous unitary states and consider an upper house or second chamber unnecessary.

Unicameral legislatures exist when there is no widely perceived need for multicameralism. Many multicameral legislatures were created to give separate voices to different sectors of society. Multiple chambers allowed for guaranteed representation of different social classes (as in the Parliament of the United Kingdom or the French States-General), ethnic or regional interests, or subunits of a federation. Where these factors are unimportant, in unitary states with weak regional identity, unicameralism often prevails. Sometimes, as in New Zealand and Denmark, this comes about through the abolition of one the two chambers, or, as in Sweden, through the merger of the two chambers into a single one, while in others a second chamber has never existed.

Ernest (Ernie) W. Chambers (born July 10, 1937) is a former Nebraska State Senator who represented North Omaha's 11th District in the Nebraska State Legislature. He is also a civil rights activist and is considered by most citizens of Nebraska as the most prominent and outspoken African American leader in the state. As a State Senator, Chambers was considered one of the Legislature's most passionate, controversial and colorful members and was characterized by some outlets of the national media as "the Maverick of Omaha," the "angriest black man in Nebraska," and "defender of the downtrodden". Due to a term limits law passed in 2000, his term in the Nebraska Legislature ended in January 2009. It is generally agreed that even after 38 years he would have easily won re-election. As he put it, "They had to change the [state] constitution to get rid of me." He is the longest-serving state senator in the history of Nebraska.

Ernie Chambers is a lifetime Omaha resident. He is a graduate of Omaha Central High School and Creighton University School of Law although he is not a member of the bar and does not practice law.

William Harrison "Bill" Withers, Jr. (born July 4, 1938) is an American singer-songwriter and musician who performed and recorded from 1970 until 1985. He recorded a number of hits such as "Lean on Me", "Ain't No Sunshine", "Use Me", "Just the Two of Us", "Lovely Day", and "Grandma's Hands". His life was recently the subject of the documentary film Still Bill.

Withers was born the youngest of six children in the small coal-mining town of Slab Fork, West Virginia. Raised in nearby Beckley, West Virginia, Withers was twelve years old when his father died. He enlisted with the United States Navy at age eighteen and served for nine years, during which time he became interested in singing and writing songs. Soon after his discharge from the Navy in 1965, he relocated to Los Angeles in 1967 for a musical career.

Withers worked as an assembler for several different companies, including Douglas Aircraft Corporation, while recording demo tapes with his own money, shopping them around and performing in clubs at night. When he debuted with the song "Ain't No Sunshine" he refused to resign his job because of his belief that the music business was a fickle industry and that he was still a novice compared to other acts.
