The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom. All of them have the United Kingdom somewhere attached to their flag, and view themselves as British citizens. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. It is the largest empire in history and, after the end of the Great War, is one of the two superpowers. By the end of the Colonialism war in 1847 the British Empire held sway over about 708 million people, one-fourth of the world's population at the time. The empire covers more than 43,296,961 sq km, almost a quarter of the Earth's total land area. As a result, its political, legal, linguistic and cultural legacy is widespread. The phrase "the empire on which the sun never sets" is often used to describe the British Empire, because its expanse across the globe meant that the sun is always shining on at least one of its territories. The British motto - peace under our rule angers the two remaining countries since the end of the British Colonialism War, the EU and the African free Nations quite a lot as the British empire said many times it would be better if the whole world would be under their rule.
Between 1815 and 1929, a period referred to as Britain's "imperial century" by some historians, around 708 million people were under the British Empire. Victory over the 13 colonies left Britain without any serious international rival, other than the European union, and the small number of Individual nations in in central Africa, away from British and French's holdings in the Black Continent. Unchallenged at sea, Britain adopted the role of global policeman, a state of affairs later known as the Pax Britannica, and a foreign policy of "helping those in need". Since the end of the 19 century Britannia had the world's largest economy, but many agree that's only because of British China whose cheap labor allows Britannia to flourish up until present day (very similar to OTL's booming Chinese economy). British imperial strength was underpinned by the steamship and the telegraph, new technologies invented in the second half of the 19th century, allowing it to control and defend the empire, but as the British Empire grew more powerful, the EU's advances in technology (especially military and space travel) seems magic by the British Empire and the free African states. By 1935, the British Empire was linked together by a network of telephones that's used by both the military and civilian population., the so-called All Red Line or commonly known as the Line' 'That Era of British peace Era ended with the collapse of the British states of America's Economic Center The Wall Street, which caused Fascism to raise in Germany, Greece, and Japan. Germany and Greece succeed the EU and form together the GRC (Greater Reich Conclave) with Japan in 1933 and eventually the Great War between the GRC and the Allies.
War in Africa
Since the 17 century Europe colonized Africa in the Scramble for Africa, looking for Resources. This ended in 1820's as British's focus turned to China and the EU focused on improving its tech and economy to rival the British Empire. With this came the Birth of the Free African Nations. This federation tried to avoid global politics in the Era of Pax Britannia. In 1935 British patrol in British's Egypt came under fire from the border with the FAN (he Free African Nations). The British, despite severing heavy casualties, managed to kill one of the attackers. The rest of the attackers fled from the Battlefield. while British Secret service discovered its was nothing at all with the FAN government and it was a Terrorist organization, The British empire hoped to make Africa whole and to remove the FAN and focused on the GRC and the EU. It declared war on the FAN and invaded them. The War was on both sides was mostly trenches. As both sides seemed able only to make a few miles in a day. However, British motive was high and had superior equipment. Britannia managed finally to advance all the way and came close of the Federation's capital, the state of Ethiopia in mid-1947. But luck was out of Brittania's Hands as the Great War in Europe begun. Britannia, obliged to aid the EU managed to form a ceasefire and a peace agreement with FAN in early 48. Between mid-1947 and the peace agreement in early 1948 FAN attempted to end the siege on Ethiopia but with no luck. Both sides stayed on their side of the border. With the agreement Britain moved its forces to Europe and return Areas taken from FAN. FAN in return, committed not to resume the War with Britannia, and not join the War in Europe or join the GRC and remain neutral in global politics in the War, and afterwards. With Britannia's bulk of forces in Europe, FAN started a military buildup to make sure it would not be threaten again by the British Empire..
The GRC (until the Great war at least), despite being a newcomer in the world quickly was very strong in both economic might (second only to Britain) and military discipline. The GRC's leaders consolidated their power from 1933 to the start of the Great War in 1947. Its Führer, Adolf Hitler claimed in Mein Kampf, a book that he published while being Führer that the EU did not attacked the British Empire because it's weak, and a puppet of the British Empire. He further claimed that GRC inevitably needed to territorially expand because it was facing an overpopulation crisis within its own designed boundaries that Adolf Hitler described: "We are overpopulated and cannot feed ourselves from our own resources". Because of this, The GRC mounted a huge military buildup and experimenting military prototype technology under the name 5 Year Plan. From 1942 to 1947 the Military was equipped with super-secret weapons such as the Gewehr 43 auto rifle, the mouse super heavy tank, and pioneering chemical weapons and missiles, something both the British Empire and the EU would only start to develop in the war and would find themselves outgunned. Up until 1947 both the British Empire and the EU said publicly they would join the war against the GRC and would support each other, both hoped they would not need to truly help each other as they still had great hate but hoped this announcement would be enough to prevent the GRC from going to war. In 1947 the GRC attacked without warning the EU under the role of expanding east just as written in Mein Kampf, hoping to utilise the fact that most of Britain soldiers were on the War for Africa (1935-1948).
