Constitution
The Constitution of the United States stands as the oldest active codified constitution in human history. It serves as a supreme law that defines how the state is governed and limits the power of rulers. This document establishes lines that government officials cannot cross, such as fundamental rights for citizens. When principles are written into a single document, they form what legal scholars call a written constitution. If these principles encompass multiple sources like court cases and treaties, the system becomes an uncodified constitution. The Constitution of the United Kingdom exemplifies this latter type through numerous acts of its legislature rather than one single text. These foundational documents determine the procedure by which laws are made and identify who holds authority within a polity. Changes to such constitutions often require consensus or supermajority votes among legislators. A treaty establishing an international organization also functions as its own constitution by defining how that entity operates. In most modern states, the constitution holds supremacy over ordinary statutory law. If an official act violates constitutional provisions, it is null and void from inception. This principle ensures that no ruler can legislate beyond their granted powers.
Excavations in modern-day Iraq by Ernest de Sarzec in 1877 revealed evidence of the earliest known code of justice issued by Sumerian king Urukagina of Lagash. This ancient document relieved taxes for widows and orphans while protecting the poor from usury practiced by the wealthy. The Code of Ur-Nammu of Ur dates back to approximately 2050 BC and remains the oldest surviving written legal code today. Draco codified oral laws in Athens during 621 BC with penalties so severe they created the modern term draconian. Solon reformed Athenian governance in 594 BC by basing ruling class membership on wealth instead of birth. Cleisthenes established democratic foundations in Athens again in 508 BC after years of aristocratic rule. Aristotle classified different forms of government around 350 BC including monarchic, aristocratic, and democratic elements. Roman law first appeared as the Twelve Tables in 450 BC before evolving into complex codes like the Codex Theodosianus in 438 AD. The Edicts of Ashoka established constitutional principles for Mauryan India during the third century BC. Japan adopted its Seventeen-article constitution in 604 under Prince Shōtoku focusing on social morality rather than governmental institutions. The Constitution of Medina drafted shortly after 622 created a formal agreement between Muhammad and tribes in Yathrib. Hywel Dda codified Welsh law around 942 through 950 serving as Wales main legal code until the sixteenth century.
The Instrument of Government adopted by England on the 15th of December 1653 marked the first written constitution enacted by a modern state. Major-General John Lambert drafted this document to establish a republic following Oliver Cromwell's victory in the English Civil War. It created a state council with twenty-one members while vesting executive authority in the office of Lord Protector. This system lasted only four years before being replaced by the Humble Petition and Advice in May 1657. Connecticut became the first North American colony to adopt a written constitution known as the Fundamental Orders in 1639. All thirteen original United States colonies adopted their own constitutions between 1776 and 1777 during the American Revolution. Massachusetts ratified its Commonwealth Constitution in 1780 making it the oldest still-functioning state constitution in America. Pylyp Orlyk wrote the Zaporizian Host agreements in 1710 establishing democratic standards for separation of powers before Montesquieu published his theories. The Polish-Lithuanian Commonwealth passed its Constitution on the 3rd of May 1791 becoming Europe's second oldest after the American example. France adopted its Constitution of 1791 shortly thereafter introducing revolutionary changes to monarchy. Venezuela promulgated its first constitution in 1812 under Cristóbal Mendoza Briceño Perozo and Juan Germán Roscio. Spain ratified its Constitution of 1812 in Cádiz serving as a model for other South European nations including Portugal and Italy.
The standard model described by Baron de Montesquieu divides government power into three branches: executive, legislative, and judicial. Most constitutions explicitly separate these functions to prevent any single entity from accumulating absolute authority. Presidential systems hold department secretaries accountable directly to the president who appoints and dismisses them. Parliamentary systems make Cabinet Ministers responsible to Parliament while the prime minister retains appointment powers. In constitutional monarchies like the United Kingdom, the monarch appoints ministers based on advice from the prime minister. When governments lose confidence votes or fail budget approvals, they must resign or call new elections. Some countries establish additional independent institutions such as central banks, anti-corruption commissions, or human rights bodies. Federal states divide sovereignty between a central structure and constituent regions like provinces or states. Unitary states concentrate all sovereign power within the state itself though some devolve authority to sub-national governments. Confederal arrangements give limited coordinating power to central structures with sovereignty residing primarily in regional entities. The European Union represents an example where member states voluntarily surrender parts of their sovereignty through treaties. These structural designs aim to create self-enforcing equilibria between rulers and powerful administrators. Rulers cannot implement policies without relying on organizations like armies courts police agencies and tax collectors. If these administrative bodies refuse cooperation they can disable governmental authority entirely.
Only two sovereign nations maintain wholly uncodified constitutions today: New Zealand and the United Kingdom. San Marino holds the distinction of having the oldest written document still governing a sovereign nation dating back to 1600. Israel's Basic Laws since 1950 serve as constitutional foundations despite lacking formal codification status. Canada operates under multiple British North America Acts spanning from 1867 to 1982 alongside unwritten conventions derived from common law. Uncodified systems evolve over centuries through laws conventions observations precedents royal prerogatives customs and traditions. The Westminster System developed in Britain exemplifies this evolutionary approach contrasting sharply with single-document codified models. Australia combines its federal constitution with statutes like the Statute of Westminster and Australia Act 1986 plus unwritten conventions. The UK Fixed-term Parliaments Act 2011 demonstrated how simple majority legislation could alter election timing previously requiring constitutional amendment. Codified constitutions often emerge from dramatic political changes such as revolutions while uncodified ones develop gradually. States with codified constitutions typically grant them supremacy over ordinary statute law allowing courts to strike down conflicting legislation. Exceptional procedures frequently require supermajority votes special constituent assemblies or referendum processes for amendments. Some countries embed entrenched clauses making certain principles impossible to abolish even through formal amendment processes. India employs a basic structure doctrine preventing Parliament from altering fundamental features despite lacking explicit entrenched provisions.
Constitutions include various rights and duties ranging from freedom of expression to obligations to pay taxes. Most nations require special procedures more stringent than ordinary legislation for any constitutional modification. Iceland Sweden Estonia and Greece demand different supermajority thresholds depending on legislative chamber composition. France Senegal Slovakia Afghanistan Angola Armenia Austria Bahrain Bangladesh Bulgaria Cambodia Djibouti Ecuador Honduras Laos Libya Malawi North Korea North Macedonia Norway Palestine Portugal Qatar Samoa São Tomé and Príncipe Serbia Singapore Slovenia Solomon Islands Turkmenistan Tuvalu United Arab Emirates Uzbekistan Vanuatu Vietnam Yemen Ukraine Belgium Bulgaria Romania Russia Turkey Albania Andorra Egypt Tunisia Uganda Zambia Seychelles Madagascar Taiwan Namibia Sierra Leone Fiji Mexico Ethiopia Poland Bosnia Herzegovina Germany Italy Jordan Namibia Netherlands Pakistan Somalia Zimbabwe Brazil Czech Republic Kazakhstan Gabon Haiti Algeria Ireland Italy Australia Switzerland Spain Japan Romania Zimbabwe Antigua Barbuda all employ unique amendment formulas involving legislatures referendums sub-national bodies or combinations thereof. The U.S. Constitution prohibits abolishing equal suffrage within the Senate without state consent representing an entrenched clause. Germany Turkey Greece Italy Morocco Iran Brazil Norway Czech Republic use eternity clauses protecting core governmental forms. India's constitution lacks specific entrenched clauses yet maintains basic structure doctrine preventing fundamental alterations. Communist state constitutions reject separation of powers vesting unified authority in supreme state organs controlled by ruling parties. Constitutional courts interpret these documents declaring void executive and legislative acts infringing constitutional provisions. Some countries like Ireland allow ordinary courts to perform this function while others such as the UK traditionally operate under parliamentary sovereignty principles.
