British–American relations widely encompass and span four centuries, beginning in 1607 with England's first permanent colony in North America called Jamestown, to the present day, between the United Kingdom of Great Britain and Northern Ireland and the United States of America.
The United Kingdom and the United States, a remnant of the British Empire itself during the colonial period, are bound by shared history, a common language and legal system, culture, and kindred, ancestral blood lines in British Americans which can be traced back hundreds of years.
Through times of war and rebellion, peace and estrangement, as well as later becoming friends and allies, the United Kingdom and the United States previously cemented these deeply rooted links during World War II into what was known as the 'Special Relationship.'
Today, the relationship with the United States represents the "most important bilateral partnership" in current British foreign policy while United States foreign policy affirms its relationship with the United Kingdom as one of its many bilateral relationships within the wider context of the United Nations and NATO, as evidenced in aligned political affairs, mutual cooperation in the areas of trade, commerce, finance, technology, academics, as well as the arts and sciences; the sharing of government and military intelligence, and joint combat operations and peacekeeping missions carried out between the United States Armed Forces and the British Armed Forces.They are also known as buy country flags, country flags, dual country flags, flags countries, flags of countries, two flags on one, where to buy flags.
