The volunteers came mainly from the middle and working classes although some were traditional territorials with existing yeomanry regiments contributing to the establishment.
The Yeomanry had existed in Britain as a volunteer organization for over a century but in December 1899, the war office decided to allow a contingent of volunteer forces based on the standing yeomanry regiments. The birth of the Imperial Yeomanry was as a result of a Royal Warrant issued on Christmas Eve 1899 when the existing Yeomanry regiments were asked to provide service companies each with 115 men. The Imperial Yeomanry was raised on a county basis, the core being men from existing volunteer units, with others recruited from volunteers which meant that men from all around the country served.
Although its purpose was to strengthen the forces in the Second Boer War, it was not disbanded until 1908 when the individual Yeomanry regiments became part of the Territorial Force. The Imperial Yeomanry was instigated because of military disasters during December 1899 at which point an extensive mounted force was judged essential to overthrow the Boers.
By the time the Second Boer War ended, around 35,000 volunteers had been recruited; its structure consisted of both companies and battalions. The existing yeomanry was asked to provide a trained nucleus on which the force could be expanded.
Primarily, the Imperial Yeomanry was set up as unit in its own right and was completely separate from the home-based force. The first contingent comprised of just over ten thousand men. Some of those who joined the first contingent built on their experience from serving in home yeomanry regiments and undertook a further three months training to hone their horsemanship and weaponry skills before embarking for South Africa.
