and allowed for more freedom of movement for both horse and rider, became increasingly popular throughout northern Europe. In the early 20th century, Captain Frederico Caprilli revolutionized the jumping saddle by placing the flap at an angle that allowed a rider to achieve the forward seat necessary for jumping high fences and traveling rapidly across rugged terrain. The modern Western saddle was developed from the Spanish saddles that were brought by the Spanish Conquistadors when they came to the Americas. These saddles were adapted to suit the needs of vaqueros and cowboys of Mexico, Texas and California, including the addition of a horn that allowed a lariat to be tied or dallied for the purpose of holding cattle and other livestock. Types In the Western world there are two basic types of saddles used today for horseback riding, usually called the English saddle and the "stock" saddle. The best known stock saddle is the American western saddle, followed by the Australian stock saddle. In Asia and throughout the world, there are numerous saddles of unique designs used by various nationalities and ethnic groups.

However, the length and angle of the flaps, the depth of the seat and height of the cantle all play a role in the use for which a particular saddle is intended. The "tree" that underlies the saddle is usually one of the defining features of saddle quality. Traditionally, the tree of an English saddle is built of laminated layers of high quality wood reinforced with spring steel along its length, with a riveted gullet plate. These trees are semi-adjustable and are considered "spring trees". They have some give, but a minimum amount of flexibility. More recently, saddle manufacturers are using various materials to replace wood and create a synthetic molded tree (some with the integrated
