By the time the Scottish Office was formed in 1885, a number of institutions of government existed exclusively for Scotland: the Board of Supervision for Poor Relief which had been established in 1828, the Fishery Board which had been limited to Scotland in 1849, the General Board of Commissioners in Lunacy (established in 1857), the Scotch Education Department (established in 1872), and the Prisons Commission, created in 1877. In 1886, a Crofters Commission was established, and lasted until 1911. In 1894, the Board of Supervision for Poor Relief became the Local Government Board for Scotland, and three years later a Congested Districts Board was established and lasted until 1911. To these were added the Scottish Board of Agriculture in 1912, the Highlands and Islands Medical Services Board the following year, and the Scottish Insurance Commissioners in 1911.
