Why did Havana’s population become more internationally diverse during the late 18th century?

Havana’s population became more internationally diverse during the late 18th century primarily due to the stimulation of trade and the gradual removal of commercial obstacles to foreigners.1

Following the British occupation of Havana in 1762, the city’s importance as a port grew significantly, thriving on the sugar and slave trades. As the century drew to a close, the easing of trade restrictions encouraged immigration from countries beyond Spain. This influx brought a variety of people to the city, including French craftsmen, British merchants, and German bankers, which contributed to Havana’s distinct international and cosmopolitan character.1
