In 1869, the opening of the Suez Canal benefited Malta's economy greatly as there was a massive increase in the shipping which entered in the port. The economy had entered a special phase. The Mediterranean Sea became the "world highway of trade" and a number of ships called at Malta for coal and various supplies on their way to the Indian Ocean and the Far East. From 1871 to 1881, about 8,000 workers found jobs in the Malta docks and a number of banks opened in Malta. By 1882, Malta reached the height of its prosperity.
