The Convention between the United Kingdom and China, Respecting an Extension of Hong Kong Territory, commonly known as the Convention for the Extension of Hong Kong Territory or the Second Convention of Peking, was a lease and unequal treaty signed between Qing China and the United Kingdom in Peking on 9 June 1898, leasing to the United Kingdom for 99 years, at no charge, the New Territories (as the area became known) and northern Kowloon, including 235 islands.
Hong Kong was under British rule from 1841 to 1997, except for a brief period of Japanese occupation during the Second World War from 1941 to 1945. It was a Crown colony of the United Kingdom from 1841 to 1981, and a dependent territory from 1981 to 1997. The colonial period began with the British occupation of Hong Kong Island under the Convention of Chuenpi in 1841 of the Victorian era, and ended with the handover of Hong Kong in July 1997.
In accordance with Article III of the Treaty of Nanking of 1842, signed in the aftermath of the First Opium War, the island of Hong Kong was ceded in perpetuity to Great Britain. It was established as a Crown colony in 1843. In 1860, the British expanded the colony with the addition of the Kowloon Peninsula and was further extended in 1898 when the British obtained a 99-year lease of the New Territories. Although the Qing had to cede Hong Kong Island and Kowloon in perpetuity as per the treaty, the leased New Territories comprised 86.2% of the colony and more than half of the entire colony's population. With the lease nearing its end during the late 20th century, Britain did not see any viable way to administer the colony by dividing it, whilst the People's Republic of China would not consider extending the lease or allowing continued British administration thereafter.
The New Territories is the largest of the three areas of Hong Kong, alongside Hong Kong Island and Kowloon. It makes up 86.2% of Hong Kong's territory, and contains around half of the population of Hong Kong. Historically, it is the region described in the Convention for the Extension of Hong Kong Territory. According to that treaty, the territories comprise the mainland area north of Boundary Street on the Kowloon Peninsula and south of the Sham Chun River (which is the border between Hong Kong and mainland China), as well as over 200 outlying islands, including Lantau Island, Lamma Island, Cheung Chau, and Peng Chau in the territory of Hong Kong.
Later, after New Kowloon was defined from the area between the Boundary Street and the Kowloon Ranges spanned from Lai Chi Kok to Lei Yue Mun, and the extension of the urban areas of Kowloon, New Kowloon was gradually urbanised and absorbed into Kowloon.
The handover of Hong Kong from the United Kingdom of Great Britain and Northern Ireland to the People's Republic of China occurred at midnight on 1 July 1997. This event ended 156 years of British rule, dating back to the cession of Hong Kong Island in 1841 during the First Opium War.
Hong Kong was a colony of the British Empire from 1841, except during the Japanese occupation of Hong Kong from 1941 to 1945. Its territory expanded after the First Opium War with the addition of the Kowloon Peninsula and Stonecutters Island in 1860 and the New Territories in 1898 under a 99-year lease. The 1984 Sino–British Joint Declaration set the terms of the 1997 handover, under which China pledged to uphold "one country, two systems" for 50 years. Hong Kong became China's first special administrative region, followed by Macau in 1999 under similar arrangements. With a population of about 6.5 million in 1997, Hong Kong made up 97 percent of the population of all the British Dependent Territories and was Britain's last major colony.
The Sham Chun River or Shenzhen River (Chinese: 深圳河; pinyin: Shēnzhèn Hé) serves as the natural border between Hong Kong and mainland China, together with Deep Bay, Mirs Bay, and the Sha Tau Kok River.
It formed a part of the limit of the lease of the New Territories in 1898 in the Convention for the Extension of Hong Kong Territory (known also as the Second Convention of Peking).
Hong Kong (1800s–1930s) oversaw the founding of the new crown colony of Hong Kong under the British Empire. After the First Opium War, the territory was ceded by the Qing Empire to the United Kingdom of Great Britain and Ireland through Treaty of Nanjing (1842) and Convention of Peking (1860) in perpetuity. Together with additional land that was leased to the British under the Convention for the Extension of Hong Kong Territory (1898), Hong Kong became one of the first parts of East Asia to undergo industrialisation.
The Sino-British Joint Declaration was a treaty between the governments of the United Kingdom and People's Republic of China signed in 1984 setting the conditions in which Hong Kong was transferred to Chinese control and for the governance of the territory after 1 July 1997.
Hong Kong had been a colony of the British Empire since 1842 after the First Opium War and its territory was expanded on two occasions; first in 1860 with the addition of Kowloon Peninsula and Stonecutters Island, as both were ceded in perpetuity, and again in 1898 when Britain obtained a 99-year lease for the New Territories. The date of the handover in 1997 marked the end of this lease.
