When did Hong Kong become a colony?

Answer 1

It was occupied by the British in 1841 during the Opium War, and later ceded to the British as part of the Treaty of Nanking that marked the end of that war. Kowloon was ceded after the second Opium War in 1860. And New Territories and Lantau in 1898

Answer 2

Hong Kong Island had been a port in the province of Kwangtung (China) before 1830's or 1840's. After the Opium War, the Island was borrowed by the British. Later (after a war or something like that), Kowloon and New Territories were borrowed by the British for 99 years. So, in 1997, all 3 areas were returned to China. Another city, Macau, was a port borrowed by Portugal in 1600's. It was returned to China in 1999.

Answer 3

In the middle of the 19th century about 1842.
