A parliament is a legislature whose power and function are similar to those dictated by the Westminster system of the United Kingdom. More generally, "parliament" may simply refer to a democratic government's legislature. The term is derived from the French parlement, the action of parler (to speak): a parlement is a discussion. The term came to mean a meeting at which such a discussion took place.^[when?] It acquired its modern meaning as it came to be used for the body of people (in an institutional sense) who would meet to discuss matters of state.

The use of the term “parliament” first occurred in 1236 in England. Previously, this group of the king’s closest advisors had been called the “council”. After agreeing to the principle of “common consent” in the Magna Carta, King John had to increase the size of this group of advisors and include more commoners. He then had to submit his requests for increased taxation to this newly expanded group. Two distinct groups emerged among the commoners: the landed gentry, and the rich merchants and lawyers.
