Pony
–
Depending on context, a pony may be a horse that is under an approximate or exact height at the withers or a small horse with a specific conformation and temperament. The word pony derives from the old French poulenet, meaning foal, a young, immature horse, but this is not the meaning, unlike a horse foal. However, on occasion, people who are unfamiliar with horses may confuse an adult pony with a foal, the ancestors of most modern ponies developed small stature because they lived on the margins of livable horse habitat. These smaller animals were domesticated and bred for various purposes all over the Northern Hemisphere, ponies were historically used for driving and freight transport, as childrens mounts, for recreational riding, and later as competitors and performers in their own right. During the Industrial Revolution, particularly in Great Britain, a significant number were used as pit ponies, ponies are generally considered intelligent and friendly, although sometimes they also are described as stubborn or cunning. Properly trained ponies are appropriate mounts for children who are learning to ride, larger ponies can be ridden by adults, as ponies are usually strong for their size. In modern use, many organizations define a pony as a horse that measures less than 14.2 hands at the withers. Different organizations that use a strict measurement model vary from 14 hands to nearly 14.3 hands, many breeds classify an animal as either horse or pony based on pedigree and phenotype, no matter its height. Some full-sized horses may be called ponies for various reasons of tradition or as a term of endearment, for many forms of competition, the official definition of a pony is a horse that measures less than 14.2 hands at the withers. However, the pony can be used in general for any small horse. Furthermore, some breeds may have individuals who mature under that height but are still called horses and are allowed to compete as horses. In Australia, horses that measure from 14 hands to 15 hands are known as a galloway, people who are unfamiliar with horses may confuse an adult pony with a young, immature horse. While foals that will grow up to be horse-sized may be no taller than some ponies in their first months of life, a pony can be ridden and put to work, while a foal is too young to be ridden or used as a working animal. Foals, whether they grow up to be horse or pony-sized, can be distinguished from adult horses by their long legs. Their heads and eyes also exhibit juvenile characteristics, furthermore, in most cases, nursing foals will be in very close proximity to a mare who is the mother of the foal. While ponies exhibit some neoteny with the wide foreheads and small size, ponies originally developed as a landrace adapted to a harsh natural environment, and were considered part of the draft subtype typical of Northern Europe. At one time, it was hypothesized that they may have descended from a wild subspecies of Equus ferus. The usefulness of the pony was noted by farmers who observed that a pony could outperform a draft horse on small farms, by the 20th century, many pony breeds had Arabian and other blood added to make a more refined pony suitable for riding

Horse
–
The horse is one of two extant subspecies of Equus ferus. It is an ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, humans began to domesticate horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses anatomy enables them to use of speed to escape predators and they have a well-developed sense of balance. Related to this need to flee from predators in the wild is an unusual trait, female horses, called mares, carry their young for approximately 11 months, and a young horse, called a foal, can stand and run shortly following birth. Most domesticated horses begin training under saddle or in harness between the ages of two and four and they reach full adult development by age five, and have an average lifespan of between 25 and 30 years. There are more than 300 breeds of horse in the world today, horses were historically used in warfare, from which a wide variety of riding and driving techniques developed, using many different styles of equipment and methods of control. Many products are derived from horses, including meat, milk, hide, hair, bone, humans provide domesticated horses with food, water and shelter, as well as attention from specialists such as veterinarians and farriers. Specific terms and specialized language are used to describe equine anatomy, different life stages, colors, depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, the oldest verifiable record was Old Billy, a 19th-century horse that lived to the age of 62. In modern times, Sugar Puff, who had listed in Guinness World Records as the worlds oldest living pony. The exception is in endurance riding, where the age to compete is based on the animals actual calendar age. The following terminology is used to describe horses of various ages, Colt, a common terminology error is to call any young horse a colt, when the term actually only refers to young male horses. Filly, A female horse under the age of four, foal, A horse of either sex less than one year old. A nursing foal is sometimes called a suckling and a foal that has been weaned is called a weanling, most domesticated foals are weaned at five to seven months of age, although foals can be weaned at four months with no adverse physical effects. Gelding, A castrated male horse of any age, mare, A female horse four years old and older

Combined driving
–
Combined driving is an equestrian sport involving carriage driving. In this discipline, the driver sits on a vehicle drawn by a single horse, the sport has three phases, dressage, cross-country marathon and obstacle cone driving, and is most similar to the mounted equestrian sport of eventing. It is one of the ten international equestrian sport horse disciplines recognized by the Fédération Equestre Internationale, the FEI classification system denotes driving competitions as Concours dAttelage, which may be either National or International. A National Event is limited to competitors of that nation, who take part according to the regulations of their National Federation. Foreign athletes may take part by invitation, an International Event must be organised under the FEI Statutes, General Regulations and Sport Rules, and may be open to competitors of all NFs. CAIs are primarily for individual athletes, however, at World Championships, competitions for national teams of three or four members run concurrently with the individual competition. There are two categories of international competitions – CAI-A and CAI-B, the CAI-A category denotes a higher level of organisation and facilities provided. Normally, it is assumed that a CA classified competition is for horses, if pony classes are involved, the letter P is added to the classification. Numbers denote the arrangement of horses in the class, World championships are denoted as Championnat du Monde Attelage. There are three World Championships for horses – Singles, Pairs and Four-in-Hand and these are held every two years, with Single Horse and Four-in-Hand Championships in an even-numbered year and Horse Pairs every odd year. In addition, a World Combined Pony Championships are held every odd-numbered year, FEI World Cup Driving, is a series of competitions for four-in-hand horse teams. Introduced in 2001, it provides a style of competition which takes place in an indoor arena. The course combines marathon and cone driving obstacles, five or six drivers, each with a team of four horses take turns to drive the course against the clock. World Cup Driving events are classified as CAI-W and take place throughout the winter months, competitions for drivers with disabilities are classified as CPEAI and the championships are held in every odd-numbered year. At the National level the sport is governed by each countrys National Federation, sometimes through a body, which will have rules based on the FEI Rulebook. Most countries hold their own National Championships, most people will start driving by joining a local organisation or club, who organise training sessions and one- or two-day competitions. Keen drivers can qualify to take part in events from which they may put themselves forward to be selected to represent their country at international competitions or World Championships. Because a driver needs a groom, its possible to take part as such

Dressage
–
Dressage is a highly skilled form of riding performed in exhibition and competition, as well as an art sometimes pursued solely for the sake of mastery. Competitions are held at all levels from amateur to the Olympic Games, at the peak of a dressage horses gymnastic development, the horse responds smoothly to a skilled riders minimal aids. The rider is relaxed and appears effort-free while the horse performs the requested movement. The discipline has a history with ancient roots in the writings of Xenophon. Much about training systems used today reflects practices of classical dressage, in modern dressage competition, successful training at the various levels is demonstrated through the performance of tests, prescribed series of movements ridden within a standard arena. A score of 9 is very good and is a high mark, all riding horses can benefit from use of dressage principles and training techniques. The most popular horse breeds seen at the Olympics and other international FEI competitions are warmblood horses bred for dressage, in classical dressage training and performances that involve the airs above the ground, the baroque breeds of horses are popular and purposely bred for these specialties. There are two sizes of arenas, small and standard, each has letters assigned to positions around the arena for dressage tests to specify where movements are to be performed. Cones with letters on them are positioned on the sidelines of the arena for reference as to where a movement is to be performed. The small arena is 20 by 40 m and is used for the levels of eventing in the dressage phase. Its letters around the edge, starting from the point of entry. Letters also mark locations along the line in the middle of the arena. Moving down the line from A, they are D-X-G. The standard arena is 20 by 60 m, and is used for tests in both dressage and eventing. The standard dressage arena letters are A-K-V-E-S-H-C-M-R-B-P-F, the letters on the long sides of the arena, nearest the corners, are 6 m in from the corners, and are 12 m apart from each other. The letters along the line are D-L-X-I-G, with X again being halfway down the arena. There is speculation as to why these letters were chosen, most commonly it is believed because the German cavalry had a 20 × 60-meter area in-between the barracks which had the letters posted above the doors. At the start of the test, the horse enters the arena at an opening at A, ideally this opening is then closed for the duration of the test, however, this is not always logistically possible, particularly at smaller competitions with few volunteers

Endurance riding
–
Endurance riding is an equestrian sport based on controlled long-distance races. It is one of the international recognized by the FEI. There are two types of long-distance riding, competitive trail riding and endurance rides. In the United States, most endurance rides are either 50 or 100 miles long, shorter rides, called Limited Distance rides, are organized for new riders to the sport or young horses being trained. However, LDs have evolved into a competition of their own, in more experienced riders. There are also longer, usually multi-day, rides as well, as with human marathon running, many riders will participate to improve their horses personal best performance and consider finishing the distance with a proper vet completion record to be a win. In the USA, the American Endurance Ride Conference sanctions endurance rides, in the UK, Endurance GB is the governing body. Winning riders can complete 100-mile rides in 14 to 15 hours, any breed can compete, but the Arabian generally dominates the top levels because of the breeds stamina and natural endurance abilities. Endurance rides and races can be any distance, though they are rarely over 160 km for a one-day competition. Organized endurance riding as a sport began in 1955, when Wendell Robie. They followed the historic Western States Trail and this ride soon became known as the Tevis Cup, and it remains the most difficult of any 100-mile ride in the world because of the severe terrain, high altitude, and 100-degree temperatures. Endurance riding first was brought to Europe in the 1960s, before the ride, horses are inspected by a veterinarian to ensure they are fit to perform in the ride. Riders may be given a map or GPS waypoints for the course, which shows the route, the places for compulsory halts, the trails frequently are marked with colored surveyors tape ribbons at regular intervals with additional ribbons or small arrow markers at turns in the trail. The ride is divided into sections, with different names, depending on sanctioning organization, after each section, horses are stopped for a veterinary inspection, where they are checked for soundness and dehydration, with their pulse and respiration taken. The riders time keeps running until their horses reach the required target, any horse deemed unfit to continue is eliminated from further competition. After the veterinary inspection, the horse must be held for a hold time. If the veterinary inspection is on the rather than at base camp, ride management usually delivers to the inspection location a cache of riders personal gear, food. While riders may compete without additional aid, sometimes referred to as riding cavalry, in upper level competition this is particularly important to efficiently prepare the horse for the vet as well as care of both horse and rider during the mandatory hold times

Eventing
–
Eventing is an equestrian event where a single horse and rider combination compete against other combinations across the three disciplines of dressage, cross-country, and show jumping. This event has its roots in a comprehensive cavalry test requiring mastery of several types of riding, Eventing was previously known as Combined Training, and the name persists in many smaller organizations. The term Combined Training is sometimes confused with the term Combined Test which refers to a combination of just two of the phases, most commonly dressage and show jumping. Eventing is a triathlon, in that it combines three different disciplines in one competition set out over one, two, or three days, depending on the length of courses and number of entries. This sport follows a format in Australia, Canada, Ireland, United Kingdom. The test is judged by one or more judges who are looking for balance, rhythm, suppleness, and most importantly, obedience of the horse and its harmony with the rider. The challenge is to demonstrate that a fit horse, capable of completing the cross country phase on time, also has the training to perform in a graceful, relaxed. The tests may not ask for Grand Prix movements such as piaffe or passage, therefore, if one movement is poorly executed, it is still possible for the rider to get a good overall score if the remaining movements are very well executed. The marks are added together and any errors of course deducted, if all four feet of the horse exit the arena during the test, this results in elimination. If the horse more than 20 seconds during the test. This phase consists of approximately 12–20 fences, or 30–40 at the higher levels, sometimes, particularly at higher levels, fences are designed that would not normally occur in nature. However, these are designed to be as solid as more natural obstacles. Safety regulations mean that some obstacles are now being built with a frangible pin system, speed is also a factor, with the rider required to cross the finish line within a certain time frame. Crossing the finish line after the optimum time results in penalties for each second over, at lower levels, there is also a speed fault time, where penalties are incurred for horse and rider pairs completing the course too quickly. For every disobedience a horse and rider incur on course, penalties will be added to their dressage score, after four disobediences altogether or three disobediences at one fence the pair is eliminated, meaning they can no longer participate in the competition. A horse and rider pair can also be eliminated for going off course, if the horses shoulder and hind-quarter touch the ground, mandatory retirement is taken and they are not allowed to participate further in the competition. If the rider falls off the horse they are eliminated, however, in the US this rule is currently being revised for the Novice level and below. The penalties for disobediences on cross country are weighted relative to the other phases of competition to emphasize the importance of courage, endurance

Paralympic Games
–
There are Winter and Summer Paralympic Games, which since the 1988 Summer Games in Seoul, South Korea, are held almost immediately following the respective Olympic Games. All Paralympic Games are governed by the International Paralympic Committee, the Paralympics has grown from a small gathering of British World War II veterans in 1948 to become one of the largest international sporting events by the early 21st century. Paralympians strive for equal treatment with non-disabled Olympic athletes, but there is a funding gap between Olympic and Paralympic athletes. Given the wide variety of disabilities that Paralympic athletes have, there are categories in which the athletes compete. The allowable disabilities are broken down into ten eligible impairment types and these categories are further broken down into classifications, which vary from sport to sport. The first athlete to do so was German American gymnast George Eyser in 1904, hungarian Karoly Takacs competed in shooting events in both the 1948 and 1952 Summer Olympics. He was an amputee and could shoot left-handed. The first organized athletic day for disabled athletes that coincided with the Olympic Games took place on the day of the opening of the 1948 Summer Olympics in London, the first games were called the 1948 International Wheelchair Games, and were intended to coincide with the 1948 Olympics. Dr. Guttmans aim was to create a sports competition for people with disabilities that would be equivalent to the Olympic Games. The games were again at the same location in 1952. These early competitions, also known as the Stoke Mandeville Games, have described as the precursors of the Paralympic Games. There have been milestones in the Paralympic movement. The first official Paralympic Games, no longer open solely to war veterans, was held in Rome in 1960,400 athletes from 23 countries competed at the 1960 Games. Since 1960, the Paralympic Games have taken place in the year as the Olympic Games. The Games were initially only to athletes in wheelchairs, at the 1976 Summer Games, athletes with different disabilities were included for the first time at a Summer Paralympics. With the inclusion of more disability classifications the 1976 Summer Games expanded to 1,600 athletes from 40 countries, the 1988 Summer Paralympics in Seoul, South Korea, was another milestone for the Paralympic movement. It was in Seoul that the Paralympic Summer Games were held directly after the Olympic Summer Games, in the same host city and this set a precedent that was followed in 1992,1996 and 2000. It was eventually formalized in an agreement between the International Paralympic Committee and the International Olympic Committee in 2001, and was extended through 2020

Reining
–
Reining is a western riding competition for horses where the riders guide the horses through a precise pattern of circles, spins, and stops. All work is done at the lope, or the gallop, the horse should be willingly guided or controlled with little or no apparent resistance and dictated to completely. Cattle were moved, branded, doctored, sorted, and herded, often on open range without the benefit of fences, a good cowboy needed a quick and nimble horse, one that could change directions quickly, stop on a dime, and sprint after an errant cow. Other nations with traditions of herding livestock on vast areas, such as Australia and Argentina, the reining pattern includes an average of eight to twelve movements which must be executed by the horse. Patterns require the following movements, Circles, the horse must perform large, fast circles at a near-gallop and smaller and they should be perfectly round, with the rider dictating the pace of the horse. There should be an easily seen change of speed as the rider transitions from the large, fast to the small, most circles incorporate changes of direction that require a flying change of lead. Flying lead change, the horse changes its leading front and hind legs at the lope mid-stride, the horse should not break gait nor change speed. Rundown, the horse gallops or runs along the side of the arena. A rundown is a required movement prior to a sliding stop, the back should be raised upward and hindquarters come well underneath. A particularly powerful stop may, depending on conditions, produce flying dirt. The movement should finish in a line, and the horses position should not change. This movement is a favorite, along with spins. Back or Backup, the backs up quickly for at least 10 feet. The horse must back in a straight line, stop when asked. It is judged on how quick, smooth and straight the line is, rollback, the horse immediately, without hesitation, performs a 180-degree turn after halting from a sliding stop, and immediately goes forward again into a lope. The horse must turn on its hindquarters, bringing its hocks well under, spins or Turnarounds, beginning from a standstill, the horse spins 360 degrees or more in place around its stationary inside hind leg. The hind pivot foot remains in essentially the same throughout the spin, though the horse will pick it up. Spins are judged on correctness, smoothness, and cadence, speed adds to the difficulty and will improve the score of a correctly done spin

Show jumping
–
Show jumping, also known as stadium jumping, open jumping, or simply jumping, is a part of a group of English riding equestrian events that also includes dressage, eventing, hunters, and equitation. Jumping classes are seen at horse shows throughout the world. International competitions are governed by the rules of the International Federation for Equestrian Sports, Show jumping events have hunter classes, jumper classes and hunt seat equitation classes. Hunters are judged subjectively on the degree to which they meet a standard of manners, style. Jumper courses tend to be more complex and technical than hunter courses because riders. Courses often are colorful and at times, quite creatively designed, hunters have meticulous turnout and tend toward very quiet, conservative horse tack and rider attire. Hunter bits, bridles, crops, spurs, and martingales are tightly regulated, formal turnout always is preferred, a neat rider gives a good impression at shows. In addition to hunters and jumpers, there are classes, sometimes called hunt seat equitation. The equipment, clothing, and fence styles used in more closely resemble hunter classes. Jumper classes are held over a course of show jumping obstacles, including verticals, spreads, the intent is to jump cleanly over a set course within an allotted time. Time faults are assessed for exceeding the time allowance, Jumping faults are incurred for knockdowns and blatant disobedience, such as refusals. Horses are allowed a number of refusals before being disqualified. A refusal may lead to a rider exceeding the time allowed on course, placings are based on the lowest number of points or faults accumulated. A horse and rider who have not accumulated any jumping faults or penalty points are said to have scored a clear round. Tied entries usually have a jump-off over a raised and shortened course, and the course is timed, if entries are tied for faults accumulated in the jump-off, the fastest time wins. In most competitions, riders are allowed to walk the initial course, going off course will cost time if minor errors are made and major departures will result in disqualification. The higher levels of competition, such as A or AA rated shows in the United States, or the international Grand Prix circuit, present more technical and complex courses. Not only is the height and width of an obstacle increased to present a challenge, technical difficulty also increases with tighter turns

Equestrian vaulting
–
Equestrian vaulting, or simply Vaulting, is most often described as gymnastics and dance on horseback, which can be practiced both competitively or non-competitively. Vaulting has a history as an act at circuses. It is open to men and women, and is one of ten equestrian disciplines recognized by the International Federation for Equestrian Sports. Therapeutic or interactive vaulting is also used as an activity for children and adults who may have balance, attention, gross motor skill, vaultings enthusiasts are concentrated in Europe and other parts of the Western world. It is well established in Germany and Switzerland and is growing in other western countries, Vaulting was first introduced in the United States in the 1950s and 60s but was limited only to California and other areas of the west coast. More recently, it is beginning to gain popularity in the United States northeast and it is believed by some that the origins of vaulting could be traced to the ancient Roman games, where acrobats usually displayed their skills on cantering horses. Others, however, believe that vaulting originated in ancient Crete, in either case, people have been performing acrobatic and dance-like movements on the backs of moving horses/animals for more than 2,000 years. Renaissance and Middle Ages history include numerous references to vaulting or similar activities, the present name of the sport/art comes from the French la voltige, which it acquired during the Renaissance, when it was a form of riding drill and agility exercise for cavalry riders. Modern vaulting developed in post-war Germany as an initiative to introduce children to equestrian sports, in 1983, vaulting became one of the disciplines recognized by the FEI. European championships were first held in Ebreichsdorf, Austria in 1984, Vaulting was included in the World Equestrian Games in Stockholm in 1990 and in all subsequent editions of the games. It was demonstrated as an art during the 1984 and 1996 Olympic Games events and it has been included in the Inter-Africa Cup since 2006. The first World Cup Vaulting competition was held in Leipzig on 29–30 April 2011, in competitive vaulting, vaulters compete as individuals, pairs, and teams. Beginning vaulters compete at the walk or trot while experienced vaulters compete at the canter, the vaulting horse moves in a 15-metre circle and is directed by a lunger who stands in the center. In competitive vaulting, the rider will first be judged on a score from 1 to 10, if two competitors tie, then the horse is judged. Vaulting competitions consist of compulsory exercises and choreographed freestyle exercises done to music, there are seven compulsory exercises, mount, basic seat, flag, mill, scissors, stand and flank. Each exercise is scored on a scale from 0 to 10, horses also receive a score and are judged on the quality of their movement as well as their behavior. Vaulters compete in team and individual freestyles, an individual Kur is a 1-minute freestyle and team is 4 minutes. They are both choreographed to music, the components of a freestyle vaulting routine may include mounts and dismounts, handstands, kneeling and standing and aerial moves such jumps, leaps and tumbling skills

4-H
–
4-H is a global network of youth organizations whose mission is engaging youth to reach their fullest potential while advancing the field of youth development. In the United States, the organization is administered by the National Institute of Food, 4-H Canada is an independent non-profit organization overseeing the operation of branches throughout Canada. Throughout the world, 4-H organizations exist in over 50 countries, each of these programs operates independently but cooperatively through international exchanges, global education programs, and communications. The 4-H name represents four personal development areas of focus for the organization, head, heart, hands, as of 2007, the organization had over 6.5 million members in the United States, from ages 5 to 21, in approximately 90,000 clubs. The goal of 4-H is to develop citizenship, leadership, responsibility and life skills of youth through experiential learning programs and a positive youth development approach. Though typically thought of as an agriculturally focused organization as a result of its history, 4-H today focuses on citizenship, healthy living, science, engineering, the 4-H motto is To make the best better, while its slogan is Learn by doing. The foundations of 4-H began in 1902 with the work of people in different parts of the United States. The focal point of 4-H has been the idea of practical and hands-on learning, early programs incorporated both public and private resources. 4-H was founded with the purpose of instructing rural youth in improved farming and farm-homemaking practices, by the 1970s, it was broadening its goals to cover a full range of youth, including minorities, and a wide range of life experiences. So rural youth programs became a way to introduce new technology to the adults. Club work began wherever a person did something to give rural children respect for themselves and their ways of life. Instances of work with boys and girls can be found all throughout the 19th century. Graham started one of the programs in Clark County, Ohio, in 1902. The first club was called The Tomato Club or the Corn Growing Club, dad Erickson of Douglas County, Minnesota, started local agricultural after-school clubs and fairs also in 1902. Jessie Field Shambaugh developed the clover pin with an H on each leaf in 1910, early 4-H programs in Colorado began with youth instruction offered by college agricultural agents as early as 1910, as part of the outreach mission of the Colorado land grant institutions. The Smith-Lever Act formalized the 4-H programs and clubs began in the midwestern region of the United States. Although different activities were emphasized for boys and girls, 4-H was one of the first youth organizations to give attention to both genders. By 1924, these clubs became organized as 4-H clubs, the first 4-H camp was held in Randolph County, West Virginia

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci
