A parade is a procession of people, usually organized along a street, often in costume, and often accompanied by marching bands, floats, or sometimes large balloons. Parades are held for a wide range of reasons, but are usually celebrations of some kind. In British English, the term "parade" is usually reserved for either military parades or other occasions where participants march in formation; for celebratory occasions, the word procession is more usual. The term "parade" may also be used for multiple different subjects; for example, in the Canadian Armed Forces, "parade" is used both to describe the procession and in other informal connotations. Protest demonstrations can also take the form of a parade, but such cases are usually referred to as a march instead. Parade float The parade float got its name because the first floats were decorated barges that were towed along the canals with ropes held by parade marchers on the shore. Floats were occasionally propelled from within by concealed oarsmen, but the practice was abandoned because of the high incidence of drowning when the lightweight and unstable frames capsized. Strikingly, among the first uses of grounded floats — towed by horses — was a ceremony in memory of recently drowned parade oarsmen. Today, parade floats are traditionally pulled by motor vehicles or are powered themselves. Parade grand marshals Multiple grand marshals may often be designated for an iteration of the parade, and may or may not be in actual attendance due to circumstances (including death). A community grand marshal or other designations may be selected alongside a grand marshal to lead the front or other parts of the parade. Aircraft and boats Since the advent of such technology, it became possible for aircraft and boats to parade. A flypast is an aerial parade of anything from one to dozens of aircraft, both in commercial context at airshows and also to mark important dates, such as national days or significant anniversaries. They are particularly common in the United Kingdom, where they are often associated with Royal occasions. Similarly, for ships, there may be a sail-past of, e.g., tall ships (as was seen during Trafalgar 200) or other sailing vessels as during the celebrations of the 60th anniversary of World War II. Longest parade The longest parade in the world is the Hanover Schützenfest that takes place in Hanover every year during the Schützenfest. The parade is long with
