Play the ball as it lies. Play the course as you find it. And if you can't do either, do what is fair

Lifting and Dropping
Through the green was first defined in 1899, as being all parts of the course except hazards and the putting green. The teeing ground was added to the definition in 1933.

Apart from taking a ball out of a hazard, lifting was initially allowed only for balls touching, then within six inches of each other from 1775.
The first 'procedure' for dropping a ball came in 1754: throwing it behind a water hazard 'six yards at least'. Apart from 1754 and HCEG 1809, all codes up to 1888 allowed a ball to be teed behind if it was in water, but the ball was to be dropped in other instances.

R &A 1858 stipulated a drop on a line from the hole behind the hazard, establishing the principle used ever since.

R&A 1891 in stroke play allowed a ball to be teed for lost ball and a ball 'lifted out of any difficulty', (in match play both these occurrences were loss of hole).

The first mention of placing, rather than dropping, a ball on the putting green came in 1902.

The method of dropping a ball had a few early variants:
1754 throw it at least six yards; 1776 Edinburgh Burgess throw it over your head; 1809 HCEG, Montrose 1830, Perth 1839 and R&A 1812 face the hole, and drop over the head; and the latter to be adopted over the shoulder from Perth 1825 and Blackheath.
When the 1899 rules came into force, the procedure was well detailed: behind the hazard, face the hole, stand erect and drop it from your head on a line from the hole.
In 1908 the new procedure of dropping over the shoulder introduced. It lasted until 1984, when the present method of dropping at arm's length was introduced.

Re-dropping was required if the ball:
1899 rolls into a hazard.
1933 rolls nearer the hole.
1946 rolls nearer hole.
1950 (R&A) goes out of bounds, into a hazard or casual water.
1952 One re-drop before placing.
1954 rolls out of a hazard.
1960 rolls more than 2 club lengths.
1964 placed at point ('spot' in 1984) where last dropped.
1980 rolls onto a putting green.
1984 rolls back into the condition from which relief is being taken.
1996 not nearer hole than point where last crossed margin of WH.

1964 two drops then place
dropped ball strikes player, play as it lies

Lifting for ID
1908 A player can lift anywhere for identification in the presence of another player.
1956 ball may not be lifted for identification in a hazard.

R&A 1891 sees the first mention of placing a ball on the putting green, no doubt at the behest of greenkeepers who around this time started keeping the area around the hole well-tended.

Marking
A ball had to be marked when lifting from the putting green from 1976, and marked if it was to be replaced anywhere from 1984.

Wrong ball
No mention was made of a wrong ball in any code until the 1800s. 1828b - play opponent's ball, play as it lies, no stroke 1815 Aberdeen play wb opponent can have stroke or replay ball
1812 R &A had a simple sentence: If the player strikes his adversary's ball with his club, the player loses the hole.

The featherie ball did not fly very far, so the issue of playing a ball from outside the match probably did not arise very often. Also the balls were far too expensive to leave behind on the course, so stray ball was a rare thing.
After the introduction of the guttie, which flew further, and the increasing popularity of golf, the possibility became real enough for the R&A to expand on a rule in 1858. Penalty for playing a wrong ball was loss of hole, however if the balls were inadvertently exchanged then there was no penalty to either side and the ball were played out thus exchanged.

1891 R&A. Penalty for playing an opponent's ball changed to 1 stroke unless this was due to wrong information, then there was no penalty and the player replaced his ball.
Playing a ball from outside the match if discovered before teeing off on the next hole was loss of hole, otherwise no penalty.

1899 Penalty back to loss of hole. Stroke play, no penalty if corrected.

1902 If a player played a ball from outside the match, there was no penalty if opponent informed before playing. Otherwise loss of hole.

1908 In stroke play no penalty for playing one stroke with a wrong ball, but DQ for two successive strokes; no penalty if played from hazard.

1933 Stroke play penalty reduced to 2 strokes, but applies to the first stroke with the wrong ball.

1950 R &A. Reduction of penalty to one stroke if the player immediately informed his opponent, otherwise loss of hole.  if player plays opponent's ball and then opponent plays a wrong ball - no penalty. For a ball outside the match 1 stroke -- treated the same.
Stroke play: 1 stroke. No penalty if played from within hazard.

1952. Playing a wrong ball is loss of hole, or 2 strokes in stroke play.

1954, added that strokes played with a wrong ball do not count in player's score.

The Wrong Rule, 1964-71
From 1964, in addition to a wrong ball, there was the possibility of playing under a wrong rule.
If a player proceeded under a rule which did not cover the case, the penalty was loss of hole, or 2 strokes, then proceed under the correct rule. Strokes played don't count.
1972 this rule was replaced by 'playing from a wrong place'.

Unplayable
An unplayable ball was not contemplated by the early rules - either you played it as it lay or you lost the hole, unless the ball was in water.  This rule was, of course, unworkable for stroke play where it was necessary to allow the player to continue the round and record a score on each hole.

Edinburgh Burgess in 1807 introduced a rule for medal play allowing a player to lift a ball at any time and drop it over his shoulder, penalty one stroke. The same rule was applied by the Honourable Company in1809, Thistle 1824 and Perth 1825.

Burntisland 1828 introduced a novel version of the unplayable ball: if the player believes he cannot play the ball, his adversary may try to do so. If the adversary either fails or declines to do so, the player can then proceed to drop the ball.
R&A, 1851 With the consent of one's adversary, a player could lift and drop behind the place for 1 penalty stroke. If the adversary disagreed, he could take two strokes at the ball to make it playable. If he succeeded then the 2 strokes were added to the players score and he played on. If not then the player proceeded with the drop.

R&A 1858 Match play, play the ball as it lies or lose the hole, except if the ball is on an obstruction or in water in which case no penalty but the ball must be played with an iron club. Stroke play, the ball may be lifted from anywhere and teed behind the place; 2 penalty strokes.

Hoylake (now Royal Liverpool) 1870: An opponent was allowed three strokes in which to make the ball playable, if he succeeded, the player incurs the additional strokes; if not, the opponent added them to HIS score!

1902. Stroke play, 2 penalty strokes and the player shall tee a ball behind the spot.

1920: Ball now can be 'deemed' unplayable anywhere on the course; penalty stroke and distance in match play, stroke and distance or tee behind the place for 2 strokes in stroke play.

Although a ball could be declared unplayable anywhere at this time, if a player's ball was in a water hazard, by following the water hazard Rule he could get back into play for one penalty stroke instead of two in stroke play (or loss of hole in match play).

The blueprint for the modern unplayable rule came from:
1941 USGA. The player is the sole judge as to whether his ball is unplayable. It may be declared unplayable at any place on the course, except in a water hazard or in casual water.
In 1947 the USGA said a ball could be declared anywhere on the course. In stroke play a ball may be lifted from any place except a water hazard, penalty one stroke.

1950. Unplayable is defined: 'if the player consider he cannot make a stroke at it and dislodge it into a playable position'.
1952 definition dropped.

Also in 1950 penalties reduced to distance only for lost, out of bounds and unplayable. Relief either distance only or within 2 club lengths, 1 penalty stroke. Provisional ball for a ball unplayable not allowed.
For more on provisional ball, see here.

1952 Lost, Unplayable, OOB all under same rule and penalties. Player is sole judge whether his ball is unplayable, and it can be declared Unplayable anywhere. Options are stroke and distance or 2 strokes and drop back on a line. Provisional ball allowed.
1960 USGA. reduced penalty to 1 stroke and removed Provisional option.
1964 option added to drop within 2-club lengths of ball, 2 penalty strokes.
1968 R&A. penalty reduced to 1 stroke, no provisional. Ball cannot now be declared unplayable in a water hazard.
