Scotland's only cavalry regiment, the Royal Scots Greys were descended from the Royal Regiment of Scots Dragoons. The regiment saw active service in many major conflicts fought by the British Army, from the Jacobite risings to the Napoleonic Wars. But World War I marked the beginning of the end for cavalry regiments which were phased out after the introduction of mechanised warfare.
- Originally made up of three independent troops of dragoons formed in 1668, they later merged with three other troops to form the Royal Regiment of Scots Dragoons in 1681.
- Earliest postings were to maintain law and order in Scotland in the run-up to the Jacobite rebellions.
- In 1693, when William III inspected the troops, the whole regiment appeared mounted on grey-coated horses and became known as the 'Grey Dragoons' or the 'Scots Regiment of Grey Dragoons'.
- These names were incorporated into its official title in 1877 when it was renamed the 2nd Dragoons (Royal Scots Greys).
