its excellent harbours became a prized asset for the British, especially after the opening of the Suez Canal in 1869. The island became a military and naval fortress, the headquarters of the British Mediterranean fleet. Home rule was refused to the Maltese until 1921 although a partly elected legislative council was created as early as 1849 (the first Council of Government under British rule had been held in 1835), and the locals sometimes suffered considerable poverty. This was due to the island being overpopulated and largely dependent on British military expenditure which varied with the demands of war. Throughout the 19th century, the British administration instituted several liberal constitutional reforms which were generally resisted by the Church and the Maltese elite who preferred to cling to their feudal privileges. Political organisations, like the Nationalist Party, were created or had as one of their aims, the protection of the Italian language in Malta. In 1813 Malta was granted the Bathurst Constitution; in 1814 it was declared free of the plague, while the 1815 Congress of Vienna reaffirmed the British rule under the 1814 Treaty of Paris. In 1819, the local Italian-speaking Università was dissolved. The year 1828 saw the revocation of the right of sanctuary, following the Vatican Church-State proclamation. Three years later, the See of Malta was made independent of the See of Palermo. In 1839, press censorship was abolished, and the construction of St. Paul's Anglican Cathedral began. Following the 1846 Carnival riots, in 1849 a Council of Government with elected members under British rule was set up. In 1870 a referendum was held on ecclesiastics serving on Council of Government, and in 1881 an Executive Council under British rule was created; in 1887, the Council of Government was entrusted with "dual control" under British rule. A backlash came in 1903, with the return to the 1849 form of Council of Government under British rule. The last quarter of the century saw technical and financial progress in line with the Belle Époque: The following years saw the foundation of the Anglo-Egyptian Bank (1882) and the beginning of operation of the Malta Railway (1883); the first definitive postage stamps were issued in 1885, and in 1904 tram service began. In 1886 Surgeon Major David Bruce discovered the microbe causing the Malta Fever, and in 1905 Themistocles Zammit discovered the fever's sources. Finally, in 1912, Dun Karm Psaila wrote his first
