The 1800s: Modern Golf Takes its Form: The 19th century is considered by many to be the period when the truly modern game emerged. The changes that primarily spurned this modernization were to the equipment of the game. Up to 1848, golf balls, as previously stated, were featheries, made of feathers and leather.
Established in 1860, the Open Championship is the oldest of golf's major tournaments and is especially known for its great tradition. It is conducted by The R&A, which derived its name from The Royal and Ancient Golf Club of St. Andrews, Scotland, and is considered to be one of the governing bodies of golf.
