In 1542, King Henry VIII required the wealthy to keep a specified number of trotting-horse stallions.
The breed was known for its ability to carry a heavy man for great distances at speeds up to 17 mph.
Trotting races (usually under saddle), were very popular in the early part of the 19th century, and Norfolk Trotters excelled in them.
A Norfolk Trotter stallion, Bellfounder, was imported to America in 1822, and proved a major influence in the founding of the Standardbred by becoming the dam sire of Hambletonian 10.
[3] Norfolk Trotters also strongly influenced today's modern Hackney horse.
