What happened to the colonies once ruled by Germany after World War 1?

The colonies formerly under the rule of Germany after World War 1 were handled according to the Treaty of Versailles. The treaty mandated that the German Empire relinquish all its overseas colonies and territories, which were then reallocated under the supervision of the League of Nations. The majority of these former German colonies were partitioned among the victorious Allied powers of World War I. Here are some of the key outcomes:

1. Pacific Ocean:

- German New Guinea: Divided primarily between the Australian Mandate of New Guinea and the Japanese South Seas Mandate.

- Nauru: Administered as a League of Nations Mandate jointly by the British Empire, Australia, and New Zealand.

- German Samoa: Mandated to New Zealand.

2. Africa:

- German East Africa (Tanganyika and Rwanda-Urundi): Divided between Britain (British Tanganyika) and Belgium (Ruanda-Urundi).

- German Southwest Africa (Namibia): Mandated to South Africa, which eventually annexed the territory in 1949.

- Togoland: Split between Britain (Togoland under British mandate) and France (Togoland under French mandate).

- Cameroon: Similarly split between Britain (the British Cameroon) and France (the French Cameroons).

3. Shandong, China:

- Reverted to Chinese control after previously being under German influence and economic domination.

These territorial changes had profound effects on the geopolitical landscape of the time and continue to have some degree of influence on international relations and regional identities today.
