The Army Bureau of Current Affairs, or ABCA, was an organisation set up to educate and raise morale amongst British servicemen in World War II.
ABCA issued pamphlets in units and promoted discussions, for instance about post-war reconstruction and the Beveridge report. It met with resistance from Winston Churchill, who felt it was a poor use of military time. The organisation is generally regarded as a factor in the landslide Labour Party victory in the post-war general election in 1945. ABCA organisers and teachers predominantly seem to have been left-wing, as were the soldiers who attended the classes, and classes became dominated by discussion of nationalisation and social justice. The service vote in the election that followed is said to have been the most dramatic reflection of the public mood, with as many as 80% of soldiers voting for the Labour Party according to some sources.
The military history of the United States spans a period of over two centuries. During those years, the United States evolved from a new nation fighting Great Britain for independence (1774–1781), through the monumental American Civil War (1861–65) to the world's sole remaining superpower of the late 20th century and early 21st century.
The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, and a federal district. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. The largest of these territories are Puerto Rico and the American Virgin Islands which are an official part of the United States. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the U.S. mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
