The American side of the Anglic Civilization is heavily defined by the 17th and 18th century developments on the North American continent. These two hundred years caused major cultural shifts away from the English culture back in Britain. When the matter came to blows, the Declaration of Independence of 1776 became the guiding credo and defining document of those differences.
Here the United States National Archive is having a reading ceremony and reenactment of the Declaration of Independence for the 4th of July, 2019, Independence Day, celebration.
