Independence Day, also referred to as the Fourth of July or July Fourth, is a federal holiday in the United States commemorating the adoption of the Declaration of Independence on July 4, 1776. The Continental Congress declared that the thirteen American colonies regarded themselves as a new nation, the United States of America, and were no longer part of the British Empire. The Congress actually voted to declare independence two days earlier, on July 2.

Independence Day is commonly associated with fireworks, parades, barbecues, carnivals, fairs, picnics, concerts, baseball games, family reunions, and political speeches and ceremonies, in addition to various other public and private events celebrating the history, government, and traditions of the United States. Independence Day is the National Day of the United States.

The Bristol Fourth of July Committee is a volunteer organization of about 120 people, dedicated to continuing the celebration that honors our many civil servants, military and fire personnel of our community. They sponsor many community and fundraising events throughout the year to support the celebration, culmination with the Parade.

The annual official and historic celebrations were established in 1785 by Rev. Henry Wight of the First Congregational Church and veteran of the Revolutionary War, and later by Rev. Wight as the Parade, and continue today, organized by the Bristol Fourth of July Committee. The festivities officially start on June 14, Flag Day, beginning a period of outdoor concerts, soap-box races and a firefighters' muster at Independence Park. The celebration climaxes on July 4 with the oldest annual parade in the United States, "The Military, Civic and Firemen's Parade", an event that draws over 200,000 people from Rhode Island and around the world. These elaborate celebrations give Bristol its nickname, "America's most patriotic town".
