The question of the duration of the colony, on the question of colonial history

This statement is inaccurate.

A leased territory is a territory leased by a State to another State for a certain period of time for the purposes specified in the treaty in accordance with a treaty. The concept of leased land is a lease relationship borrowed from national law. Sovereignty over leased land is not transferred.

The lease is valid only for the agreed period, during which the lessor acquires the right to use the territory.

9 June 1898: Britain forced Qing ** to sign the "Treaty on the Extension of the Boundary of Hong Kong", leasing the area north of Boundary Street on the Kowloon Peninsula and 262 nearby islands for a period of 99 years (ending on 30 June 1997).

The term of the lease, 99 years versus 100 years, does not change the nature of the event. In 1903, the United States and Panama entered into the Treaty on the Excavation of the Transoceanic Canal, according to which Panama permanently ceded to the United States the "use, possession, and control" of the 10-mile-wide strip of land required for the construction of the Panama Canal, similar to Lend-Lease but not identical, because it was "permanent" and indefinite. However, after the resolute struggle of the Panamanian people, in 1977 the United States** and Panama** signed a new "Panama Canal Treaty", agreeing that Panama would gradually regain jurisdiction over the Canal Zone and set a time limit for the return of the Canal Zone to Panama along with the canal.

The colonies themselves were unequal treaties, and there was no question of duration. The most important thing is that you have the conditions to fight for independence or to return.

Hong Kong was colonized by the British for more than 140 years. Please verify!

Maybe it's because the history books you read don't cover everything very thoroughly.

The colonial empire of Spain.

The Spanish colonial empire was mainly a brutal plunder of Latin Americans and Indians, including the expulsion of Indians and black slaves from the slave trade to exploit gold and silver minerals, as well as the establishment of large plantations and the use of indigenous and black slaves for production.

These riches were plundered to Spain for the royal family and nobles to squander, and did not flow into the reproduction of industrial handicrafts, leading to the ** revolution in Spain and other European countries, and finally the wealth was transferred to Britain, the Netherlands and other countries with developed capitalist industry and commerce, becoming the main ** of capitalist primitive accumulation.

Spain during the reign of the Habsburgs (16th-17th centuries).

The Spanish Empire reached its peak during the reign of the Habsburgs, followed by a decline in decline. Emperor Charles V of the Holy Roman Empire, the Spanish Empire under King Carlos I of Spain reached its limits in Europe.

Spain went downhill from the end of the 16th century. The Dutch Revolution, the Armada was routed by the British, and Spain's maritime power was severely weakened. Subsequently, Spain gradually lost Jamaica and other West Indies and European possessions.

Step by step, Spain went into decline. Although he remained a large colony overseas, Spain was often swept up in feudal dynasties and clans as new shipping routes opened up and the capitalist economy developed.

Spain has a strong feudal tradition, although it is the pioneer of opening up new routes, but unlike the British, Spain plundered a large amount of wealth for the extravagant life of the royal family, but not for the progress of productivity, resulting in its development in modern times far behind the British.

declined, and the wealth of the colonies was not used to develop the productive forces, but to live a life of luxury, so it was later overtaken by Britain and the United States.
