Since the Chinese Empire participated in colonial activities, the empire's colonial achievements have been remarkable, not only capturing half of North America but also opening up a large number of colonies in East Africa. North America is said to be suitable for the colonization activities of industrial countries in the middle and high latitudes, but like Africa, the colonization activities of European countries have been hindered by diseases and harsh environments, so the European colonization of Africa is concentrated in the coastal areas, and they have not yet been able to go deep inland.

And because of Lin Hong's preparation, with advanced Chinese and Western medicine manufacturing technology and perfect epidemic prevention measures, malaria is not a problem at all on the land of East Africa, coupled with the huge population base of the empire, there is now a huge colony in East Africa.

In fact, all European countries are learning from China's colonial methods, and they can basically meet the current colonial activities by learning China's mosquito control and importing a large number of Chinese medicines. Lin Hong could fully foresee that the great era of colonizing Africa was coming.

Europe has a long history of colonizing Africa. Dating back to the Roman Empire, Rome established a province in North Africa, but was not a colony. After the fall of the Western Roman Empire, its African provinces were divided between the Eastern Roman Empire, the Frankish Empire, and the Visigothic Kingdom. During the Byzantine Empire, provinces were also established in North Africa. The period from the 15th century to the 17th century was the partial occupation of the coastal areas of Africa by Spain and Portugal, and the colonization area was not large, and the interior was not colonized by colonizers.

The first African colony to be occupied by modern European countries was the Portuguese occupation of Ceuta in Northeast Africa in 1415. The port originally belonged to Morocco, but Portugal finally captured the port of Ceuta after careful planning in order to eliminate local pirates and control the import of West African gold and ivory goods through Ceuta. Subsequently, in order to establish direct contact with the black empire of West Africa, which produced gold, it advanced along the west coast of Africa, and then occupied African islands such as Madeira and Cape Verde.

As the Renaissance developed rapidly in Europe, the ambition for commercial wealth emerged in European countries. Portugal was the first to occupy a number of coastal strongholds along the coast of Africa as a stopover to India, which the Portuguese called trading points. And these depots were actually the precursors of the colonies.

From 1442 onwards, the Portuguese pioneered the slave trade by using African Berbers as slaves in Portugal. The Spaniards, on the other hand, began to make a profit by transporting African slaves into the Americas in harsh ways from the 16th century. The high demand for the slave trade led to the construction of many trading posts and trading posts (i.e., small colonies) along the coast of West Africa, and the new European capitalist countries such as Britain, France, the Netherlands, and Denmark also joined in colonizing Africa. These trading posts and trading posts were mainly for the sale of black slaves, ivory, gold, and chili peppers. However, because the coast of West Africa was relatively inaccessible and the local terrain and climate were unsuitable for European habitation, European colonization of Africa in the following centuries was limited to a few coastal strongholds, trading posts, and trading posts, and no large-scale territorial occupation was carried out. At that time, the colonies in West Africa were basically resource-predatory colonies, not territory-grabbing colonies.

During this period, European powers began to set up slave companies, and African colonization began to increase.

However, at that time, African colonization was limited to the coastal areas, setting up trading posts, and did not penetrate deep into the interior.

In the 17th and 20th centuries, the Ottoman Empire began its colonization of North Africa.

At that time, the Ottoman Empire had a strong military force and easily occupied the Mediterranean coast of North Africa and the Red Sea coast of East Africa to establish colonies. The North African colonies occupied by the Ottoman Empire at that time included Egypt, Tripoli, Algeria, Tunisia, Morocco, Sudan, Eritrea, Somalia, etc.

In the 19th century, the Ottoman Empire's North African territories were gradually divided among Western European powers, and its East African territories were also seized by colonial powers such as Italy, Britain, and France. The Ottoman Empire's era of African colonization officially ended in 1912 with the occupation of Tripoli, its last African colony.

In the 17th and mid-18th centuries, Spain and Portugal began to decline, and in turn they were replaced by new capitalist powers, which began their era of colonization of Africa.

In 1526, the English also began the African slave trade and set up a trading establishment. Soon, Denmark and the Netherlands, as transit countries for European trade, joined the slave trade in an attempt to get a piece of the pie. Small states such as Sweden, Brandenburg, Hamburg, and Courland also rose during this period, and they all engaged in the slave trade in an attempt to profit from it. To this end, these countries also occupied some strongholds on the coast of Africa, and African colonization began to expand. As the indigenous economy in West Africa is dominated by gatherers and hunters, food production is extremely limited. In order to supply the food of the black slaves on the way, the colonists opened up new agricultural areas around these strongholds, and introduced new crops from Europe and the Americas, such as sweet potatoes and potatoes, as a food supply.

The Industrial Revolution led to the industrialization of European countries, and the original black slaves were no longer needed, causing the growth of African colonies to stop.

After the Industrial Revolution, the colonial trade in Africa, which was dominated by the production of sugar, tobacco and the slave trade, was no longer profitable for the colonial powers due to the advent of machines. The urgent demand for industrial raw materials such as cotton, wool, copper, tin, and coal in the industrial countries has replaced the original demand for consumer goods, and at the same time, these countries are saturated with local markets, so they urgently need to open markets outside their own countries to sell the large quantities of industrial products produced in these countries and thus make huge profits. At this time, the British also occupied the Cape Colony (South Africa) in Africa.

Due to the French Revolution's concept of human rights and various religious, humanitarian, and economic reasons, Britain finally outlawed the slave trade in 1807 and ceased its slave trade. Since then, the Netherlands, France, Sweden, Denmark and other countries have also banned the slave trade and stopped all slave trade. As a result of this measure, the trade points and trading points of the colonial powers along the African coast were no longer important and quickly disappeared and shrunk. Denmark and the Netherlands sold off all their trading posts off the coast of West Africa in the mid-19th century. The demand for black slaves plummeted, and the colonial power and sphere of influence of Spain and Portugal in Africa quickly weakened and disappeared.

At the same time in North Africa, France took advantage of the decline of Ottoman Turkey and used the pretext of eliminating North African pirates to infiltrate and attack Algeria, Morocco, Tunisia and other Turkish dependent countries, and Algeria, which was the most active pirate, was hit the hardest by France, and in 1815 the French Navy defeated the Algerian Navy, and in 1819 the Anglo-Dutch combined fleet bombarded the capital Algiers, and France also had many armed conflicts with Algeria. Eventually, in 1830, France occupied the coastal areas of Algeria.

Between 1825 and 1875, with the exception of Britain and France, the conquest of new colonies and the expansion of territories by European countries largely ceased and were replaced by a movement of mass emigration to overseas colonies. In the case of Britain, a quote by British Prime Minister Disraeli in 1852 can be said to be the best summary of Britain's attitude towards colonies during this period: "Colonies are a heavy grinding disc hanging around our (Britain's) necks." In the case of the two small British colonies in The Gambia and the Gold Coast, the commercial tax revenues were far from keeping up with the administrative costs, and the British Parliament recommended several times that the colonies should be reduced or abandoned altogether, only because the British Royal Navy's West African Squadron needed to establish a naval base in the Gulf of Guinea to prohibit the slave trade.

However, in order to house the emancipated black slaves in the Caribbean islands, Britain established the colony of Sierra Leone during the period of colonial decline by establishing an authorized company, the American Colonization Society established the colony of Liberia during the same period, and the French colony of Libreville (present-day Gabon), all of which were used to house freed slaves.

If there is a map of African colonies, then it is obvious that the Chinese Empire is now the country that occupies the most land in Africa
