Over 90% of the population are slaves (officially referred to as 'serfs' as the Draka maintain the fiction that they are part of the British Empire, which outlaws slavery). In fact the entire Drakan society, from sex to the economy, is based on slavery. Almost all Draka citizens own at least a few slaves.
The Dominion draws substantially from the ideology of Friedrich Nietzsche and can be viewed as an "Anti-America" - in the sense that like the United States, the Draka nation started off as a British settler colony, but evolved along diametrically opposite lines. While the United States had slavery, even slave-holders had to pay lip-service to the American values of liberty and equality, and the contradiction was eventually resolved by the American Civil War. The Draka, on the other hand view themselves as a master race and unlike the Nazis, actually try their utmost to be such - all Draka citizen children attend sex-segregated boarding schools with an extreme Sparta-like emphasis on physical fitness.
Politically, the Draka state is described as 'aristocratic republic' with a parliamentary system of government. The Archon, the head of state appointed by parliament (elected in free and fair elections), serves for a 20-year term. Draka citizens have a considerable degree of free speech, but fundamental criticism of the slave system is forbidden. The Draka economy is heavily dominated by cartels known as Combines, with ownership split between the state and the Landholders' League (Citizens can only own the right to use land, not the land itself, which can be confiscated in the event of neglect or misuse). There is also a considerable small-business private sector.
Because the Draka are so heavily outnumbered, meaning that a general slave rebellion could well mean their extermination, the Draka are utterly ruthless. Impalement is the favoured Draka method of executing rebellious slaves. By 1900 the Draka have conquered and enslaved all of Africa. The last areas to be conquered were the jungles of the Congo, due to the danger of tropical diseases.
Meanwhile, the United States has annexed Mexico outright after the Mexican-American War. William Walker's Southern adventurers conquer Central America. During the American Civil War the Draka supply massive amounts of aid to the Confederacy, including steam-powered armored cars. However, the Union still wins the Civil War, and annexes Walker's central American empire, along with Hawaii, the Caribbean islands and the Philippines. All these territories eventually give the United States a total of 62 states.
In World War I the Dominion of the Draka loyally joins the Allied side, and conquers the Ottoman Empire, before declaring independence from Britain, renaming itself the Domination of the Draka. It then takes advantage of the Russian Civil War to take over much of Central Asia, and partitions China with the Japanese Empire.
At this stage, under the influence of Draka philosophers such as Elvira Naldorssen, the traditional Draka white-supremacism is replaced by Draka-supremacism, with the Draka viewing all of non-Drakan humanity as their cattle. Elvira explains the ideology of the Domination, the utter amorality of which will lead enemies of the Draka to refer to them as 'Snakes':
"...so the Draka are not different from other peoples because they violate the Golden Rule or Bentham's derivative idolatry 'the greatest good for the greatest number'. Everyone does. We do not violate them, we reject them.
Others have conquered and ruled; we alone conquer for conquest's sake and Dominate for no other purpose than Domination itself; the name we half-consciously chose for our state is no accident. We, and we alone have spoken aloud the Great Secret; that the root function of all human society is the production and reproduction of power - and that power is the ability to compel others to do your will against theirs. It is end, not means. The purpose of Power is Power.
The Draka will conquer the world for two reasons; because we must and because we can. And yet of the two forces the second is the greater; we do this because we choose to do it. By the sovereign Will and force of arms the Draka will rule the Earth, and in so doing remake themselves. We shall conquer and beat the Nations of the Earth into the dust and reforge them in our self wrought Image; the Final Society without weakness or mercy, hard and pure. Our descendants will walk the hillside of that future, innocent beneath the stars, with no more between them and their naked will than a wolf has. THEN there will be Gods in the Earth."
The first book of the series Marching Through Georgia is a war story set during the Eurasian War, the Domination timeline's equivalent of World War II. Due to the additional danger of invasion on its southern border by the Domination, the Soviet Union was completely crushed by the Nazis, with only a Siberian rump state surviving under a junta led by Marshal Timoshenko. The Domination entered the war just before the Nazi invasion of Russia, conquering Italy with the tacit consent of the Nazis. Now the Draka have attacked the Third Reich itself, in the Caucasus region.
The Draka citizen soldiers, female as well as male, are honed killing machines, each equal to several of their enemy on the battlefield. They are equipped with superb weaponry - while the German army is equipped with Panther and Tiger tanks, the Draka have 14,000 Hond III tanks - equivalent in armor, engine size and gun caliber to the M1 Abrams and other real-world tanks of the present day.
For attritional warfare the Domination uses it Janissary slave soldiers, who make up 60% of the Draka army. Draka soldiers neither ask nor give quarter - all captured enemies are killed or permanently enslaved.
After the attack on Pearl Harbor annihilates the entire American Pacific Fleet, with the States of Hawaii and the Philippines under Japanese occupation, and fighting a desperate battle to expel a Japanese invasion of the mainland, the United States is totally unable to open a second front in Europe, while alliance with the Nazis against the Draka is blocked by the Jewish lobby (which naturally see the Nazis as a worse evil due to the Holocaust), and by a Draka threat to supply Japan with nuclear materials and research information in the event of US-German peace.
As a result, once the United States eventually defeats Japan, the Draka have conquered all of mainland Europe and most of Asia. One of the most powerful and horrific aspects of "Marching Through Georgia" is most non-Jewish readers will find themselves rooting for the Nazis, who try in vain to defend Europe against an enemy whose atrocities dwarf those of Hitler and Stalin. In total, the Eurasian War claims some 200 million lives, over three times the death toll of our own World War II.
The second book Under the Yoke is a horrific vision of Europe under Draka rule. By now the United States has set up the "Alliance for Democracy", an economic and military union of the 11 remaining free countries - the United States, the countries of South America, the UK, Japan, India, the South-east Asian and Australasian Federations, and the Indo-Chinese republic.
The Alliance secret service, the OSS is attempting to keep a resistance movement alive in Europe, but this is impossible in the face of Draka ruthlessness. In 1952, when a slave rebellion takes over the city of Barcelona, the Draka respond with a thermonuclear bomb.
The third book The Stone Dogs tells the story of the Protracted Struggle - the ultra-nasty Cold War between the Domination of the Draka and the Alliance for Democracy. There is a far more intense space race in this world, with colonies and military bases established on the Moon, on Mars and in the asteroid belt.
In the 1970's, just as in our world, there is a major setback for the Free World. An OSS covert operation, designed to discredit a Hindu nationalist party and keep India in the Alliance, backfires as the Draka assassinate the Indian president and plant a suicide note implicating the OSS in the scandal. As a result India secedes from the Alliance - and is conquered and enslaved by the Draka within weeks (except Burma, which counter-seceded and rejoined the Alliance). After the 'Indian Incident' the Alliance for Democracy is formally converted into a single superstate.
The much larger free population of the Alliance give it an edge in physics and computer technology, while the Domination carries out vivisection on its slaves, thus gaining the upper hand in the biological sciences. Both sides develop their respective super-weapons with which to launch the first strike of the inevitable final war...
