The kingdom is mentioned in the Periplus of the Erythraean Sea as an important market place for ivory, which was exported throughout the ancient world. Aksum was at the time ruled by Zoskales, who also governed the port of Adulis. The Aksumite rulers facilitated trade by minting their own Aksumite currency. The state also established its hegemony over the declining Kingdom of Kush and regularly entered the politics of the kingdoms on the Arabian peninsula, eventually extending its rule over the region with the conquest of the Himyarite Kingdom.

The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militias—frequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.
When did the unification complete of all the Canadian forces to be called the Canadian Army?
November 1940

Britain's fears of war with Germany were realised in 1914 with the outbreak of the First World War. Britain quickly invaded and occupied most of Germany's overseas colonies in Africa. In the Pacific, Australia and New Zealand occupied German New Guinea and Samoa respectively. Plans for a post-war division of the Ottoman Empire, which had joined the war on Germany's side, were secretly drawn up by Britain and France under the 1916 Sykes–Picot Agreement. This agreement was not divulged to the Sharif of Mecca, who the British had been encouraging to launch an Arab revolt against their Ottoman rulers, giving the impression that Britain was supporting the creation of an independent Arab state.
When WW1 began, Britain took the opportunity to take over most of which country's colonies?
Germany
