Following in the path struck out by Miss Strickland in her Lives of the Queens of England, and by Lord Brougham's Lives of Eminent Statesmen, he at last produced, in 1849, The Lives of the Lord Chancellors and Keepers of the Great Seal of England, from the earliest times till the reign of King George IV., 7 vols.
Strickland established a new system of education based on the principle of beginning from the bottom, by teaching to read and write in Maltese as the medium for assimilating, at a further stage, either English or Italian, one at a time, and aiming at imparting general knowledge in colloquial English.
As successor to the Order, the Crown claimed and eventually established (by the negotiations in Rome of Sir Frederick Hankey, Sir Gerald Strickland and Sir Lintorn Simmons) with regard to the presentation of the bishopric (worth about £4000 a year) the right to veto the appointment of distasteful candidates.
A regulation excluding Maltese from the navy (because of their speaking on board a language that their officers did not understand) provoked from Trinity College, Cambridge, the Strickland correspondence in The Times on the constitutional rights of the Maltese, and a leading article induced the Colonial Office to try an experiment known as the Strickland-Mizzi Constitution of 1887.
Strickland, who had been elected while an undergraduate on the cry of equality of rights for Maltese and English, and Mizzi, the leader of the anti-English agitation, were, as soon as elected, given seats in the executive council to co-operate with the government; but their aims were irreconcilable.
