Nations

Within the Hellsing world, there are multiple countries and continents mentioned specifically in each series; to an extent, the manga mentioned the US and the anime mentioned the "Dark Continent", which is a clear reference to Africa.

United Kingdom
The United Kingdom of Great Britain and Northern Ireland or also, the United Kingdom or Britain is a country in Europe, and the main location in which; the Hellsing story takes place in. Known as one of the many countries left that still ruled by Kings and Queens, in the Real World, it's currently ruled by King Charles the Third, but however; in Hellsing, the Monarch is Queen Elizabeth the Second. With the likes of the The Convention of Twelve, the Government along with the Queen had built a secret organisation in which, specializes in killing supernatural creatures such as vampires and ghouls, however sometimes; zombies.

The organisation is of course, the Hellsing Organisation and also known as, the Royal Order of Protestant Knights, in which, was founded by Abraham Van Helsing and their approval of the Hellsing family to keep one vampire alive, whom is the most powerful of them all. Despite this, these creatures are told to not be talked about; in case of public panic, in which, the vampires and ghouls would definitely take advantage of. Furthermore, these creatures are kept so secretive that the police doesn't even know about them. The Hellsing Organisation is tasked by the Government and to an extent, probably her highness too.

World War II
They are heavily involved in World War II, and in 1939 after the Nazi Germany had invaded Poland, they declared war on them and sided with Poland, the US and others who were there to fight Germany. However, during the war; they had noticed that the Führer was creating a secret weapon that could defeat the Alliance singlehandedly, and because of this; they tasked the Hellsing Organisation into destroying it; in which, Arthur Hellsing had ordered young Walter C. Dornez and its trump card, Alucard, into doing so. They were indeed successful in killing the scientists. However, its higher ups escaped and was eventually, forgotten.

Present Day, 1999
The rise of vampires are quite concerning, and meetings were held after the news that vampires had some kind of chip implanted onto their brain in order to become the undead. However, in the middle of the meeting; chaos ensues after two unknown men had invaded the Hellsing Manor directly, where the meeting was being held. It was surely planned and after the defeat of those men, they were turns out, to be sent to attack the manor by an unknown organization that held a grudge to them.

However eventually, with the help of the Vatican, they were found and their name is; Millennium, a secret organization that survived long enough because of the Vatican; whom they helped because of their shared hatred towards Communism. Section 13th Iscariot, agreed to help wipe Millennion out and a meeting was being held with the Queen of England involved. However, was interrupted yet again by a member of Millennion, who can seemingly teleport; known as Schrödinger. He was only there to send a message from the leader, the Major whom declared war upon Great Britain and the Queen of England tasked the Hellsing organisation to destroy them, in which, they obey and sure enough; they immediately attacked the messenger. However, he disappeared and then, Sir Integra Fairbrook Wingates Hellsing goes on to talk with Sir Shelby M. Penwood.

United States of America
The United States of America, also known as the United States, or America is a country located in North America, which provides a minor; yet pivotal role in Hellsing, specifically; during the Battle of London.

World War II
Playing a major role during the second World War, the US first started out as Neutral; however, began supplying material to the Allies in March of 1941. On December 7, 1941, the Japanese suddenly launched a surprise attack on Pearl Harbor, which ended up killing 2,403 U.S. personnel, causing the US to join the Allies in the war against the Axis powers. Nearing the end of World War II, the US dropped an atomic bomb on Hiroshima and Nagasaki, which caused the Japanese to eventually surrender and the war finally ends.

Present Day, 1999
During a meeting in the White House, Millennion suddenly attacked and ended up killing 13 other cabinet members including, the president himself, after the presidential aide, Matthew Zell, had turned into a vampire. Because of this, a battle between the US army and the Battalion erupts and eventually; the White House ended up being inflames, and this news was almost instantly informed to Iscariot. After the attack, the army positioned themselves around the presidential residence and however, despite the news being sent to them for clearly, an aid in battle; Enrico Maxwell had ordered the commanders to not move a finger, telling them to let themselves take action if damage escalates; because their chaos apparently, "benefits" them.

However, Millennion had not advanced further after the attack on the White House and therefore; the US was left alone fighting for themselves, and eventually; they survived and can be assumed correctly that they moved on.
