Commissioners of Supply were local administrative bodies in Scotland from 1667 to 1930. Originally established in each sheriffdom to collect tax, they later took on much of the responsibility for the local government of the counties of Scotland.
In many cases the commissioners appointed special constables for all or parts of their counties, and by the Police (Scotland) Act 1857 they were required to establish a county police force, in all areas outside police burghs, from 1858.
As local goverment was reformed in 1890 they ceded most of their duties to the county councils created by the Local Government (Scotland) Act 1889. The Commissioners of Supply were finally abolished in 1930 by the Local Government (Scotland) Act 1929.
