Miniature horses were first developed in Europe during the 1600s, and by 1765, they were seen frequently as the pets of nobility. Miniature horse life span is 25 to 35 years, but often live longer, with the oldest known ones living 50 years of age.
The English began using small ponies in their mines. At the peak of this practice in 1913, there were 70,000 ponies underground in Britain. In later years, mechanical haulage was introduced on the main underground roads replacing the pony haulers. As of 1984, 55 ponies were still in use at the pit in Ellington, Northumberland. When Ellington closed in 1994, the last four pit ponies were brought out.
