Despite Malta's rapid transformation into a strategic naval base during the British period, the influence of Italian culture on Malta strengthened considerably throughout the 19th century. This was due in part to increasing levels of literacy among the Maltese, the increased availability of Italian newspapers, and an influx of Italian intelligentsia to Malta. Several leaders of the Italian risorgimento movement were exiled in Malta by the Bourbon monarchs during this period, including Francesco Crispi, and Ruggiero Settimo. Malta was also the proposed destination of Giuseppe Garibaldi when he was ordered into exile; however, this never came to pass. The political writings of Garibaldi and his colleague, Giuseppe Mazzini – who believed that Malta was, at heart, part of the emerging Italian nation – resonated among many of Malta's upper- and middle-classes.
