During the Victorian Era, the regiment took part in the Crimean War, the Anglo-Egyptian War, the Mahdist War, and the Second Boer War.

Grenadier Guards [SEP] Introduction
The Grenadier Guards (GREN GDS) is an infantry regiment of the British Army. It can trace its lineage back to 1656 when Lord Wentworth's Regiment was raised in Bruges to protect the exiled Charles II. In 1665, this regiment was combined with John Russell's Regiment of Guards to form the current regiment, known as the 1st Regiment of Foot Guards. Since then, the regiment has filled both a ceremonial and protective role as well as an operational one. In 1900, the regiment provided a cadre of personnel to form the Irish Guards; while later, in 1915 it also provided the basis of the Welsh Guards upon their formation.
