A constitution is a set of rules for government—often
codified as a written document—that establishes principles of an autonomous political entity. In the case of countries, this term refers specifically to a national constitution defining the fundamental
political principles, and establishing the structure, procedures,
powers and
duties, of a
government. By limiting the government's own reach, most constitutions guarantee certain
rights to the people. The term constitution can be applied to any overall
law that defines the functioning of a government, including several historical constitutions that existed before the development of modern national constitutions.
Constitutions concern different kinds of
political organizations. They are found extensively in regional government, at
supranational (e.g.,
European Union),
federal (e.g.,
Indian Constitution),
state or provincial (e.g., the
constitution of the Commonwealth of Massachusetts or the
constitution of the State of New York), and
sub-national levels. They are also found in many political groups, such as
political parties,
pressure groups, and
trade unions.
Non-political entities such as
corporations and
voluntary associations, whether incorporated or not, may also have a
constitution. The constitution of a legally incorporated entity is more usually styled as its
memorandum and
articles of association (U.S.
incorporation).
Constitution of India is the longest written constitution of any sovereign country in the world, containing 448 articles, 12 schedules and 94 amendments, thereby totaling 117,369 words in its
English language version.
Etymology
The term constitution comes from a
Latin term denoting an important law, usually one proclaimed by the Roman emperor ("constitutiones principis": the edicta, mandata, decrera and rescripta). Later, the term was widely used in
canon law for an important determination, especially by the
Pope, which are now referred to as
apostolic constitutions
