Corporation of London

The Lieutenancy of the City of London in its modern form was founded by an Act of Parliament in 1662. Under the Act of 1662 the Lieutenants for the City of London were commissioned to levy the trained bands and to raise a Trophy Tax for defraying the necessary charges and incidental expenses of the Commission. The Lieutenancy had multifarious responsibilities in connection with the trained bands and the auxiliaries (later the London Militia) including the appointment of officers, conduct and discipline, training and exercise, pay, equipment and recruitment. The militia was of consequence not only during periods when invasion was feared, but also had an important public order role.

The second element of the 1662 Act, the raising and spending of the Trophy Tax was a major concern of the Lieutenants. The tax was levied about once every three years. The Lieutenancy assessed the Trophy Tax on the wards but 'the Common Council for each ward' apportioned it among the individuals. Having been collected, the Trophy Tax accounts were certified by the London Quarter Sessions of the Peace and printed in the City accounts for the year it was laid before the Justices. The tax was used to fund the auxiliaries and the militia. In particular it financed the accomodation for the staff and headquarters of the militia. For the period 1796 to 1801 the militia headquarters were housed in the building which formerly had been Surgeon's Hall. After the militia was disembodied in 1801 the Lieutenants decided that the building was 'a very heavy and unnecessary expense' so the building was sold back to the City in March 1803. Later a new Militia Headquarters was built in 1825 in Bunhill Row on land set aside in the Artillery Ground, but changing circumstances necessitated the move to smaller premises at 23 Euston Square around 1837. However a larger headquarters for the militia was deemed necessary again in the 1850s. The new building was built on a portion of the Artillery Ground and was completed in 1857. Known as Finsbury Barracks, it was occupied by the Quartermaster and staff of the Royal London Militia.

The Trophy Tax was used also for making grants to further the aims of the auxiliary and volunteer forces of the City. For example in 1733 the Lieutenancy granted £500 for the building of Armoury House, the headquarters of the Honourable Artillery Company. The plans and specification submitted by the Artillery Company survive in the Lieutenancy's papers.
