Unification Wars

The Unification Wars (also known as the Wars of Unification) was a series of conflicts fought during the late 28th Millennium and early 29th Millennium, where the Emperor of Mankind revealed himself and began his conquest of Terra to unify the nations of the world.

History
During the turbulent era known as the Age of Strife, the Terran solar system and its outlying systems that had been colonised by Humanity during the Dark Age of Technology, were effectively cut off due to massive warp storms. During this dark time, Terra held sway over the local system, at other times Mars or Luna were dominant. The different worlds found themselves constantly at war. During the 28th Millennium, Earth's governments had completely broken down and the planet had divided into dozens of inter-warring nations. Continuous warfare reigned for two-and-a-half thousand years. Little remained of the once sophisticated civilisation of Earth's past. Techno-barbarian warlords and their warrior hordes continuously fought over the planet, which had become little more than a massive battleground for their wars of attrition.

This was a dark period for the people of Earth where they were dominated by brutal rulers and despotic tyrants. It was against this period of history that the Emperor of Mankind first revealed himself to the people of Earth. In secret, he had been planning for moment in history for millennia. With his massive army of enhanced proto-Space Marines, the Emperor began his conquest of Terra; to reunited the warring nations into a unified world, and then begin his reconquest of the galaxy. Brutal rulers such as Kalagann of Ursh, Cardinal Tang, and the most infamous of all, the half-mad half-genius Narthan Dume Tyrant of the Pan-pacific Empire would all fall by the wayside, as the armies of the Emperor swept all before them like wheat before the harvester's scythe.

During this time the Emperor had a number of military organisations created, such as the Imperial Army, which would become the nucleus of his armed forces to support his Astartes Legions and his reconquest of Terra. This including such venerable regiments as the Geno Five-Two Chiliad, which would become one of the oldest and most respected regiments within the Imperial Army. The geno-soldiers of this regiment was created through the earliest developments of genetic engineering. Through genetic engineering and selection the standard geno-soldiers displayed preferential characteristics of the perfect warrior - physically tougher, stronger and superior in every aspect. This Imperial Army regiments would go on to continue serving the Emperor after the conclusion of the Unification Wars. These surviving regiments would eventually be referred to as the Old Hundred, forming the initial military force at the outset of the Emperor's galaxy-spanning Great Crusade in M29.

Nations of Terra
This are the names of the tribes that existed during this era and their theorized locations:

*Yndonesic Bloc - Indonesia
 * Alba - Alberta/Albania
 * Britonnica - Britain
 * Europa - Middle,Southern and Mediterranean Europe
 * Franc - France
 * Gyptus - Egypt
 * Hy Brazil - Brazil
 * Jermani - Germany
 * Merica - America
 * Nordafirk Conclaves - Libya, Tunisia, Morocco
 * Nordyc - Norway, Sweden, Finland
 * Panpacific Empire - Pacific Islands, Japan, Australia
 * Urals/Terrawatt - Urals, Ukraine, Western Russia
 * Ursh (Asia/Russia) - Ursh was the mightiest empire on Terra before the Unification Wars and was therefore the biggest enemy to the Emperor's forces of Unity. Though Ursh was a strong empire, it wasn't as technically advanced, for the acquisition of the superior machines from the Nordafrik conclaves were their main reasons for war.  Ursh was ruled by the despot Kalagann.  Kalagann is described as a being of cruel character, commanding vast armies of techno-barbarians.  Other high positions were most likely inhabited by army generals, because it was a time of total war more than of politics (This generals included Lurtois, Sheng Khal (also: Shang Khal) and Quallodon.  The armies of Ursh consisted of mostly technobarbarians and human soldiers.

One of the last of the tyranical warlords to fall during the closing days of the war was Dalmoth Kyn. Despite his defeat, the Emperor allowed his descendant Pherom Sichar to remain within the new Imperial government though the actions of Malcador the Sigillite ensured that Sichar never sat on the Council of Terra.
