Golf originated in Scotland and has been played for several centuries in the British Isles. The oldest known course in the world is The Old Links at Musselburgh. Golf has been played on Musselburgh Links since 1672. Although often viewed as an elite pastime, golf is increasingly popular and continues to attract ever more players around the world.

Many holes include hazards, namely bunkers (or sand traps), from which the ball is more difficult to play than from grass, and water hazards (lakes, ponds, rivers, etc.). Special rules apply to playing balls that come to rest in a hazard, which make it highly undesirable to play a ball into one. For example, a player must not touch the ground in a hazard with a club prior to playing a ball, not even for a practice swing. A ball in a water hazard may be played as it lies or may be replaced by dropping another ball outside the water, but a penalty is incurred in the latter case.

The grass of the putting green is cut very short so that a ball can roll easily over distances of several metres or yards. "To putt" means to play a stroke, usually but not always on the green, where the ball does not leave the ground. The direction of growth of individual blades of grass affects the roll of a golf ball and is called the grain. The hole must have a diameter of 108 mm and a depth of at least 100 mm. Its position on the green is not static and may be changed from day to day. This hole on the green has a flag on a pole positioned in it so that it may be seen from some distance, but not necessarily from the tee. This flag is often called "the pin".

The borders of a course are marked as such, and beyond them is out of bounds, that is, ground from which a ball must not be played. Special rules determine how a golfer may proceed when his or her ball is very close to certain man-made objects on the course (obstructions) or resting upon ground in abnormal condition.

Every hole is classified by its par. The par of a hole is primarily but not exclusively determined by the distance from tee to green. Typical lengths for par three holes range from 100 to 224 m, for par four holes from 225 to 434 m, and for par five holes 435 m and greater. Par is the theoretical number of strokes that an expert golfer should require for playing the ball into any given hole. The expert golfer is expected to reach the green in two strokes under par (in regulation) and then use two putts to get the ball into the hole. Many 18-hole courses have approximately four par-three, ten par-four, and four par-five holes. The total par of an 18-hole course is usually around 72.

At most golf courses there are additional facilities that are not part of the course itself. Often there is a practice range, usually with practice greens, bunkers, and a driving area (where long shots can be practiced). There may even be a practice course (which is often easier to play or shorter than other golf courses). A golf school is often associated with a course or club.

Each course is measured out and has its own course rating. This rating defines how many strokes you get on top because of the difficulties. For example if a course is very high rated, you will get, depending on your handicap, one or two strokes as a bonus. So, if you have a handicap of 7, you should be able to play a 79 in a tournament. If it is a high rated course and you get two strokes as a bonus, you can even play a 81 and still have played your handicap 7.

Players commonly drive motorized electric carts, or walk, over the course, either singly or in groups of two, three, or four, sometimes accompanied by caddies who carry and manage the players' equipment and give them advice. Each player plays a ball from the tee to the hole, except that in the mode of play called foursomes, two teams of two players compete, and the members of each team alternate shots using only one ball, until the ball is holed out. In all modes of play, when individual players have all brought a ball into play, the player whose ball is the farthest from the hole is next to play. In some team events, a player who is farthest from the hole may ask his or her partner who may be closer to the hole to play first. When all players of a group have completed the hole, the player or team with the best score on that hole has the honor, that is, the right to play first on the next tee.

Each player acts as marker for one other player in the group, that is, he or she records the score on a score card. In stroke play (see below), the score consists of the number of strokes played plus any penalty strokes incurred. Penalty strokes are not actually strokes but penalty points that are added to the score for violations of rules or for making use of relief procedures in certain situations.

If you wish to play on a golf course, you have to pay a certain fee. There are two different fees: the range fee, which is for the driving range; and the green fee, which allows play on the golf course itself. The green fee differs from 20$ up to 425$ Pebble Beach Golf Links for 18 holes.

The two basic forms of playing golf are match play and stroke play.

The underlying principle of the rules is fairness. As declared on the back cover of the official rule book: "play the ball as it lies", "play the course as you find it", and "if you can't do either, do what is fair". Some rules state that:

The etiquette of golf, although not formally equivalent to the rules, are included in the publications on golf rules and are considered binding for every player. They cover matters such as safety, fairness, easiness and pace of play, and players' obligation to contribute to the care of the course.

There are strict regulations regarding the amateur status of golfers [2]. Essentially, everybody who has ever taught or played golf for money (or even accepted a trophy of more than a modest monetary value) is not considered an amateur and must not participate in amateur competitions.

Golf was usually regarded as a Scottish invention, as the game was mentioned in two 15th-century laws prohibiting the playing of the game of "gowf". Some scholars, however, suggest that this refers to another game which is much akin to shinty or hurling, or to modern field hockey. They point out that a game of putting a small ball in a hole in the ground using golf clubs was played in 17th-century Netherlands. Primatively, the action of using a stick with a boxed attachment to hit stones close to a marked target, similar to that of bocce, originated in Italy. The term golf is believed to have originated from a Germanic word for "club". It has been hypothesised that golf is actually an acronym for gentlemen only; ladies forbidden, but this is believed to be an urban legend.

It is an urban legend that golf courses contain 18 holes because that was the number of shots it took to polish off a fifth of scotch. According to the USGA however, this is incorrect. The links at St. Andrews occupy a narrow strip of land along the sea. As early as the 15th century, golfers at St. Andrews established a customary route through the undulating terrain, playing to holes whose locations were dictated by topography. The course that emerged featured eleven holes, laid out end to end from the clubhouse to the far end of the property. One played the holes out, turned around, and played the holes in, for a total of 22 holes. In 1764, several of the holes were deemed too short, and were therefore combined. The number was thereby reduced from 11 to nine, so that a complete round of the links comprised 18 holes.

The oldest playing golf course in the world is The Old Links at Musselburgh. Evidence has shown that golf was played on Musselburgh Links in 1672 although Mary Queen of Scots reputedly played there in 1567. The major changes in equipment since the 19th century have been better mowers, especially for the greens, better golf ball designs, using rubber and man-made materials since about 1900, and the introduction of the metal shaft beginning in the 1930s. Also in the 1930s the wooden golf tee was invented. In the 1970s the use of metal to replace wood heads began, and shafts made of graphite composite materials were introduced in the 1980s.
