Final answer:
During the mid-1800s, the British Navy focused on ending the slave trade for moral and economic reasons, and they were ultimately successful in their efforts due to their powerful presence on the seas and cooperation with other countries.
Step-by-step explanation:
During the mid-1800s, the British Navy focused on ending the slave trade, similar to their efforts against piracy in the past. Britain took this stand for several reasons. Firstly, moral reasons played a role as there was growing opposition to slavery and a desire to end this inhumane practice. Additionally, economic reasons were a factor as Britain sought to assert its dominance in the global economy by promoting free trade and abolishing the slave trade.
Ultimately, the navy was successful in their efforts due to a combination of factors. The British Navy's powerful presence on the seas made it difficult for slave ships to operate without getting intercepted. The British also signed treaties with other countries to cooperate in the suppression of the slave trade, further undermining its operations.
