Author Note: I will readily admit I'm not great writer but I feel that I am capable of writing a worthwhile story as I feel there a very few of them available. I like to pay attention to detail and will probably face some writer blocks due to them so I welcome ideas from any and all readers and will definitely take them into consideration.

Introduction:

This will be a "what if Lelouch remained in Britannia fanfic". I will admit not all of my facts and ideas are original but can anyone say that after reading all the different fanfics that any idea could be original. I try to deviate them as much as possible.

Lelouch will not be a weakling in this story like he is in canon(honestly can anyone possibly be that weak). I won't make him godlike but still he'll be a warrior capable of holding his own in a fight. He'll inherit his mother's skill with a knightmare (he is not an ace but become extremely skilled from being taught by his mother since he is six and a lot of practice while in military academy).

I'll be starting off with his childhood and move on from there. I'll try to be as detailed as possible but since so little is known about the Imperial family I'll be flying blind there. If it's possible could someone please explain to me how the numbering of the princes and princesses are done.

However, If I am to follow my own logic, they are numbered according to birth then all the princesses after Cornelia should be younger than Lelouch as he is older than Euphemia (the third princess) and their places in line for the throne are determined originally by their mother's position and afterwards based on their own merits (if they have any), this way only a strong leader will end up ruling Britannia. I would make sense since Lelouch's mother, Marianne, is a commoner by birth but ascended to the Knights of the Round and is the 5th Queen Consort (giving her seniority over many of the other consorts). I believe the nobility might have had something to do with Lelouch being seventeenth in line if that is the case. I will go into detail with that as the story goes on.

Timeline :

1 a.t.b. (55 BC) - 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. Through Eowyn's leadership, the Roman invasion of the British Isles is repelled; this marks the official beginning of the Holy Britannian Empire, with Eowyn becoming the first Emperor. At the same time, this also marks the beginning of the Imperial calendar, better known as Ascension Throne Britannia.

55 a.t.b. (1 AD) - The establishment beginning of the Gregorian calendar, better known as Anno Domini (Latin for "In the year of our Lord"). While Britannia continues to use the Imperial calendar as its standard, the Gregorian calendar comes into use through most of Europe.

1010 a.t.b. (955 AD) - Sakuradite (known as the "Philosopher's Stone" at the time) is discovered near Stonehenge in the British Isles. The scarcity of sakuradite impedes the research to turn it into a viable energy source.

1349 a.t.b. (1294 AD) - Marco Polo journeys further into the East than anticipated, reaching Japan and discovering the nation has a large deposit of sakuradite. This discovery marks the beginning of Japan's influence upon the world.

1547 a.t.b. (1492 AD) - An expedition under Christopher Columbus discovers the New World: a formerly untouched continent rich with land and resources. Columbus suspects it to be an extention of Asia, but is proven wrong by Amerigo Vespucci, who shows the world that it's an entirely separate continent. As a result, European interest in exploration and colonization increases rapidly, with many countries seeking to establish a foothold in this new land. The continent later becomes known as America.

1630 a.t.b. (1575 AD) -Empress Elizabeth I, who remained single throughout her life, bears a son, Henry IX. The potential fathers — Robert Dudley, 1st Earl of Leicester; Robert Devereux, 2nd Earl of Essex; and Carl, Duke of Britannia — gain influence and power with this knowledge.

1658 a.t.b. (1603 AD)- Henry IX ascends to the throne after the death of his mother, starting the Golden Age of the Tudor Dynasty.

1675 a.t.b. (1620 AD) - The cargo ship Mayflower brings Britannian settlers to the New World, who then established the first Britannian colony, Plymouth. Not long after, much of the eastern coast falls under Britannian control.

1811 a.t.b. (1756 AD) - The Seven Years' War erupts throughout Europe, and not even the New World colonies are left unscathed, i.e. the French and Indian War.

1818 a.t.b. (1763 AD) – The Treaty of Paris is signed, east side of the Mississippi and Canada are ceded to Britannia.

1830 a.t.b. (1775 AD) - The Washington Rebellion occurs, in which separatists under George Washington, known formally as the Continental Army, rebel against Britannian rule over the American colonies. Edward, Duke of Britannia, bribes Benjamin Franklin with promises of titles and territories in the colonies, who was charged with appealing to King Louis XVI of France for assistance in the American colonies' war for independence. Thereafter, Benjamin Franklin is given the title of Earl.

1836 a.t.b. (1781 AD) - As a result of Franklin's betrayal, the French stay out of the war. Thus, the Continental Army suffers a decisive defeat during the Siege of Yorktown with the death of George Washington, marking a severe blow to the American movement for independence.

1840 a.t.b. (1785 AD) - The Western world enters the Age of Revolution, with numerous national revolutions taking place, save Britannia, under the rule of Henry X, who continues to hold absolute monarchy.

1854 a.t.b. (1799 AD)- The French Revolution ends with the Coup of 18 Brumaire, in which Napoleon Bonaparte appoints himself as France's new leader. Working with other newly liberated European nations, he forms the European Union, in which he installs himself as the first Chancellor.

1858 a.t.b. (1803 AD) - Britannia purchases the uncharted territory of Louisiana from the French with the modern day equivalent of 60 million Euros. Not long after, Britannians begin to settle more and more toward the west, eventually expanding Imperial control all the way to the western coastline of North America.

1860 a.t.b. (1805 AD) - The EU combined fleets under Napoleon defeats the Britannian naval force under Vice Admiral Horatio Nelson at the Battle of Trafalgar. Not long after, London is occupied.

1862 a.t.b. (1807 AD)- Empress Elizabeth III retreats to Edinburgh, where a revolutionary militia arrests and forces her to abdicate, ending the monarchy and forcing the entirety of the British Isles to fall under EU rule. This event became known as The Humiliation of Edinburgh.

1863 a.t.b. (1808 AD)- Ricardo von Britannia, Duke of Britannia, and his friend and subordinate, Sir Richard Hector, Knight of One, spring Elizabeth III from prison and bring her and her followers to the New World, where a new capital is established in Plymouth. Ricardo von Britannia is then made head of the Britannian army.

1867 a.t.b. (1812 AD) - As an act of vengeance for losing their original homeland, the Britannians launch a full military offensive against the EU affiliated Commonwealth of Canada. In Britannia this became known as the War of Vengeance, whereas in the EU it would later be referred to as the War of 1812 (AD). Despite a hardened resistance, Britannian forces effectively expel all European forces from the continent, and as a result Canada and the majority of the north-western hemisphere come under Imperial control, making it the new Britannian homeland. Britannia also moves to reinforce its other territories such as Falkland Islands and Gibraltar from further EU attacks.

1868 a.t.b. (1813 AD) - Elizabeth III nominates Ricardo von Britannia (who is secretly her lover) as her successor upon her death. She ends her reign for being "the Empress who loved throughout her stormy life".

1876 a.t.b. (1821 AD) - Napoleon Bonaparte dies on his way back to France, after his defeat against Gebhard von Brucher and the Prussian Separatist Army at the Battle of Waterloo.

1879 a.t.b. (1824 AD) – Britannia invades Mexico reaffirming its control over all of north-western hemisphere.

1920 a.t.b. (1865 AD) - Jefferson Davis, Duke of Virginia, attempts to create the democratic based Britannian Confederacy from the Empire's southern territories, sparking a civil war that erupts throughout the continent. Among his supporters are legendary Generals Robert E. Lee, J.E.B. Stuart and Thomas "Stonewall" Jackson. After a long and costly war, Imperial forces loyal to 89th Emperor Abraham lin Britannia, who are commanded by General Ulysses S. Grant, emerge victorious and Britannia is reunified. This event is referred to as the Britannian Civil War. The reconciliation after the war strengthens loyalty to the Imperial Throne.

1945 a.t.b. (1890 AD) -The Republic of Japan emerges after the end of the Boshin War, in which the ruling Shogunate was removed and replaced with a western influenced republican government. It is speculated by many historians that Britannia and/or the European Union secretly spurred and supplied the rebel faction to gain better access to Japan's sakuradite deposits. The first Prime Minister of Japan is Mutsuhito Meiji, and as such the period is referred to as the Meiji Era. Eventually Japan becomes entirely modernized and emerges as a world power during this time period.

1955 a.t.b. (1900 AD) - The "Emblem of Blood" era. During this period, assassination and betrayals were frequented among members of the Imperial Family that coveted the throne. At the same time, Sixth Prince Victor zi Britannia and Seventh Prince Charles zi Britannia are born under Empress Diana zi Britannia, who herself is later assassinated. As well, the Britannian capital is moved from Plymouth on the east coast to the newly created city of Pendragon, which sits upon the undeveloped county of Arizona in the southwest. The reason behind this is unknown.

1966 a.t.b. (1911 AD) - The Xinhai Revolution occurs in Imperial China, in which the ruling Qing Dynasty is expelled and replaced by a new ruler ship, the Jiang Dynasty. This new line of Emperors would then embrace the ideal of Communism as pertained by western philosophers Karl Marx and Friedrich Engels, causing a string of social renewals in the country. These renewals included the abolishment of the Chinese class system, the centralization of resources and agriculture, and the establishment of a council of High Eunuchs that officially represented the will of the people to the Emperor/Empress as advisors. All of these changes, as well as territorial growth, would cause the birth of the Chinese Federation, the third world superpower comparable to Britannia and the EU.

1969 a.t.b. (1914 AD) - Britannia's 95th Emperor Fredrick von Britannia is assassinated by nationalist Gavrilo Princep while visiting Sarajevo, Bosnia. This single act sparks the first Great World War, in which Britannia, seeking vengeance for the assassination, openly invades Europe. New weapons of war such as machine guns, tanks and aircraft are brought forth during this conflict by both sides. In the end, the war concludes on a stalemate, with only Britannia gaining a foothold in Morocco, but not before both sides take heavy losses. Thus, it is negotiated at Nuremburg that in exchange for Britannia withdrawing from European soil, the EU would pay reparation of 32 billion euros (about 28 billion Britannian pound sterling) in gold bars for the Emperor's murder. Not long after, Germany becomes the dominant power in the EU, having been Europe's main supplier of weapons and soldiers during the war.

1970 a.t.b. (1915 AD) - Britannia enters into a brief war with the recently established Chinese Federation over mineral deposits discovered deep within the Pacific Ocean, where after hard fighting the two nations negotiate equal sharing of the minerals in Luoyang. This event is marked as the First Pacific War.

1973 a.t.b. (1918 AD) - Fearing territorial encroachment from Britannia or the EU, the Chinese Federation expands its borders by conquering foreign lands, starting with its neighbor India, an event that would later become known as the War of the Orient. Eventually the Federation comes to encompass land from Afghanistan to the west all the Korean Peninsula to the east. However, this growth in territory comes costly to the Federation combined with the brief war with Britannia three year before, as its key resources soon become drained, leading to an outgrowth of poverty to overtake the land.

1975 a.t.b. (1920 AD) - Marianne Lamperouge is born in Pendragon. Although a commoner, she would later ascend to the realm of nobility as a Knight, eventually becoming one of the elite Knights of the Round. Her grace, power and beauty would attract the eyes of many men, namely Seventh Prince Charles zi Britannia.

1983 a.t.b. (1928 AD) - Britannia expands its territories into the American continent's lower regions, taking in the entirety of Latin America and South America as well as the associated islands. In only a seven years, the entirety of the western hemisphere and roughly one-third of the planet falls under Britannia's banner. Charles zi Britannia gains great popularity for being the leader of the invasion.

1998 a.t.b. (1943 AD) - 97th Emperor Albert za Britannia is overthrown by Charles zi Britannia, who becomes the 98th Emperor of the Holy Britannian Empire. In standard royal tradition, he takes on many consorts. Among them is Marianne Lamperouge, who takes on the name Marianne vi Britannia upon her ascension. This marks the first time in Britannia's entire existence in which a commoner has become Empress, causing both praise and uproar throughout the Empire. Charles crushes all rebel factions within the Empire's conquered territories who attempt to gain independence. He then goes on to consolidate the Empire's military might making it the most dominant super power in world.

1999 a.t.b. (1944 AD) - Marianne's first child Lelouch is born, who becomes the Eleventh Prince and seventeenth in line to the throne. Four years later, Marianne's second child Nunnally would be born, who in turn becomes the Eleventh Princess and eighty-seventh in line to the throne. It should be noted that during this period, Emperor Charles spent much time with Marianne and their young son and daughter, reportedly more than with any of his other wives and children.

2009 a.t.b. (1954 AD) – Marianne vi Britannia is assassinated in her home at Aries Palace. Princess Nunally is caught in the cross fire, as a result is crippled and loses sight in both eyes. Prince Lelouch seeks an audience with his father the Emperor. The following meeting would later become known as the "Disgrace of the Black Prince". Many nobles secretly celebrate the death of Marianne.

2010 a.t.b. (1955 AD) - the Indochinese Peninsula is conquered by Britannia and becomes Area 10. In response, Japan, which was originally neutral, aligns its policy with the European Union and Chinese Federation in order to apply economic pressure upon Britannia -- an event referred to as the Oriental Incident. Both Chinese Federation and the EU and their allies blockade the ports of Britannia, hoping to force negotiations.

As a result, Britannia retaliates by invading Japan, causing the Second Pacific War. During this one month war, Britannia employs a new weapon which completely overwhelms the Japanese forces: the Knightmare Frame. The end result is the conquering of Japan by Britannia, with Japan becoming a formal colony of Britannia. It is renamed Area 11 and its natives become known as "Elevens".

Wing Zero Alpha (who kindly enough allowed me to use most his timeline).

Note: I changed the year in which Britannia invades South America from Wing Zero Alpha's. Charles is the one who led the invasion. This resulted in him gaining the loyalty of most of the military so that when he usurped the throne he was not opposed by either the military or the populous. He crushes all rebel faction destroying almost hope from ceding from the Empire. He also eliminated most of the royalty of his generation as well as the nobles and soldier that opposed him.
