Unicameralism is the practice of having only one legislative or parliamentary chamber. Many countries with unicameral legislatures are often small and homogeneous unitary states and consider an upper house or second chamber unnecessary.
Unicameralists claim that an upper house makes no sense in a democracy, saying that if an upper house is democratic, it simply mirrors the equally democratic lower house, and is therefore unnecessary. They argue that the functions of a second chamber, such as reviewing or revising legislation, can be performed by parliamentary committees, while further constitutional safeguards can be provided by a written Constitution.
In many instances these states had a second chamber and subsequently abolished it. This is either because an elected upper house had duplicated the lower house and obstructed the passing of legislation, like the Landsting in Denmark (abolished in 1953), or because an appointed chamber had proven ineffectual, like the Legislative Council in New Zealand (abolished in 1951).
Examples of single chamber parliaments or legislatures
Virtually all city legislatures are also unicameral in the sense that the city councils aren't divided into two chambers. Until the turn of the 20th century, bicameral city councils were common in the United States.

Some of the subnational entities with unicameral legislatures include Nebraska and the Virgin Islands in the United States, the Australian state of Queensland, all of the provinces and territories in Canada, all of the German Bundesländer (Bavaria having abolished its Senate in 1999), and all of the Italian Regioni.
The parliament, which is also referred to as the Estates of Scotland, the Three Estates, the Scots Parliament or the auld Scots Parliament (Eng: old), met until the Acts of Union merged the parliament of Scotland and the Parliament of England, creating the new Parliament of Great Britain in 1707.
The Parliament of the United Kingdom was originally formed in 1707 by the Acts of Union that replaced the former parliaments of England and Scotland - the Irish Parliament was subsumed into the Imperial Parliament in 1801.
