United States of America
The Unites States of America has an active and organized libertarian movement. The extremely liberal first amendment of the US Constitution protects free speech and association. The USA is home to libertarian political parties, think tanks, and publications.
The libertarian movement in the USA often appeals to values of the American Revolution, especially the Anti-Federalists and the Bill of Rights. It is also influenced by the individualist anarchist tradition. American libertarians often use the symbols of the Statue of Liberty and the Gasden Flag, with the phrase "DONT TREAD ON ME".
Objectivism and anarcho-capitalism were largely developed by Americans. The United States borders Mexico and Canada and has much migration and trade with each of those countries. The United States also has particularly strong interactions with the United Kingdom.
