Beginning in the late 19th century, as the trade union and labor movements grew, trade unionists proposed that a day be set aside to celebrate labor. “Labor Day” was promoted by the Central Labor Union and the Knights of Labor, which organized the first parade in New York City. Through the years the nation gave increasing emphasis to Labor Day. The first governmental recognition came through municipal ordinances passed during 1885 and 1886. From these, a movement developed to secure state legislation. The first state bill was introduced into the New York legislature, but the first to become law was passed by Oregon on February 21, 1887. During the year four more states — Colorado, Massachusetts, New Jersey, and New York — created the Labor Day holiday by legislative enactment. By the end of the decade Connecticut, Nebraska, and Pennsylvania had followed suit. By 1894, 23 other states had adopted the holiday in honor of workers, and on June 28 of that year, Congress passed an act making the first Monday in September of each year a legal holiday in the District of Columbia and the territories.
Inndependence Day of the United States, also referred to as Fourth of July or July Fourth in the U.S., is a federal holiday commemorating the adoption of the Declaration of Independence on July 4, 1776, by the Continental Congress declaring that the thirteen American colonies regarded themselves as 13 independent states, and no longer part of the British Empire.
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.
