Legislative Assembly is the name given in some countries to either a legislature, or to one of its branch. The name is used by a number of member-states of the Commonwealth of Nations, as well as a number of Latin American countries.
A number of colonies in the British Empire were given a degree of involvement in running their own affairs by the creation of a representative body, often named the Legislative Assembly. Typically the Legislative Assembly was partially or wholly elected by popular vote; this was usually in contrast with the other chamber of the legislature, called the Legislative Council, whose membership was generally either nominated by the Governor, or indirectly elected. Conflict between the two chambers frequently led to the Legislative Council being reformed, or even abolished outright, thus leaving the Legislative Assembly as either the more powerful chamber in the parliament, or the only one.
The modern-day Legislative Assembly in a Commonwealth country, either as a national or sub-national parliament, is in most cases an evolution of one of these colonial legislative chambers.
