World History

The World History of the Code Geass Universe differs markedly from our own, mostly in the outcome of major battles and war, but also in the appearance of materials like Sakuradite and immortals like C.C..

Imperial Calendar
The date used in Code Geass settings use the Imperial Calendar, in which years are labeled as a.t.b or "Ascension Throne Britannia". It is set to the date the first Celtic super-king, Eowyn, was elected by the united British tribes to battle Rome, becoming the first member of the modern Britannian imperial family. This calender is used by the Holy Empire of Britannia. It functions similarly to the standard Gregorian "B.C./A.D." calendar, but is set approximately fifty-five years earlier.

What calendar the other nations may use is unknown. The fact the birth of Christ is not used may suggest that Christianity was never established in the Universe; however, in the English dub, Lloyd mentions "Onward Christian Soldiers", and the appearance of a Catholic Nun in the second season suggests that it does exist but is not widely practiced. Most Britannians do not appear to practice Christianity while some do, as Shirley Fenette's family is shown to practice a form of Protestant Christianity, likely Anglicanism. Indeed, religion is rarely mentioned in the original Japanese version, but is referenced more frequently in the English dub.

Timeline

 * 55 B.C. or 0 a.t.b.
 * Julius Caesar attempts to invade Britain, but is met with strong resistance from the local tribes, who elect a super-leader: the Celtic King Eowyn, who summarily becomes the first member of the Britannian Imperial Family. The Julian Calendar (a.u.c. / ab urbe condita) is made ten years later and the Anno Domini Calendar 1,637 years later. Either the two might be used by other countries aside from Britannia and its colonies. The Celts will later adopt Roman law and order which they will establish Britannia, which is Latin for Britain
 * Unknown years - Middle Ages
 * Sakuradite (known as the "Philosopher's Stone" at the time) is discovered near Stonehenge. The scarcity of sakuradite impedes the research to turn it into a viable energy source. However, in his travels, Marco Polo journeys further into the East, reaching Japan and discovering the nation's large deposit of sakuradite.
 * 17th Century a.t.b.
 * Elizabeth I, who remained single throughout her life, bears a son, Henry IX. The potential fathers — Sir Robert Dudley, 1st Earl of Leicester; Sir Robert Devereux, 2nd Earl of Essex; and Sir Carl, Duke of Britannia — gain influence and power with this knowledge.
 * Henry IX ascends to the throne after the death of his mother in 1603 A.D. or 1658 a.t.b., starting the Golden Age of the Tudor Dynasty.

 * Middle of the 19th Century a.t.b.
 * The western world enters the Age of Revolution, with numerous national revolutions taking place, except in the British Isles, under the rule of King Henry X, who continues to hold absolute monarchy. This leads to the formation of the Euro Universe.

However, Sir Ricardo von Britannia, Duke of Britannia, and his friend and subordinate, Sir Richard Hector, Knight of One, bring Elizabeth III and her followers to the New World and establish a capital on the east coast of North America. Though Britannian rebels and revolutionaries who have overthrown the monarchy still occupy the British Isles and become citizens of it.
 * 1868 a.t.b. / 1813 A.D.
 * Elizabeth III nominates her lover, Sir Ricardo von Britannia, as her successor upon her death. She ends her reign for being "the Queen who loved throughout her stormy life".

 * 1876 a.t.b. / 1821 A.D.
 * Napoleon Bonaparte dies on his way back to France, after his defeat at the Battle of Waterloo; although it was never proven, it is rumored that assassins poisoned his food in accordance to Elizabeth III's will. Her last words included the famous line, "I do not forget slights to my honour."
