The Constitution of the United Kingdom of Great Britain is not a single specific document that can be pointed to, like the Constitution of the United States. Instead the British have developed a system of rules that establishes the political governance of the island nation. However, there are a number of documents, Acts of Parliament, and international treaties that together form the body of the Constitution of the United Kingdom. Those documents include; the Magna Carta, The Bill of Rights, 1687, the Act of Union 1707, The Act of Union 1801, and the Anglo-Irish Treaty 1928. The United Kingdom of Great Britain is widely recognized as the cradle of modern democracy. The British spread their style of government across the globe during their imperial period. Countless current democratic governments across the world owe their democracies to the British constitution. Even the Constitution of the United States of America, that was drafted during a rebellion against the British Empire, owes much of its substance to British political philosophy grounded in the Magna Carta, and enlightenment philosophers like John Locke.
