Prior to the Suchaz Invasion of Meristeppe, Suchaz's leader, Reuben Kale, had secretly been building up a highly powerful military as the economy of Suchaz began to heal, along with its society. He had been planning for the military's reconstruction since replacing Eulas Krarev as Eminent Curator of Suchaz.
The WarOn Sepreindus VIII, 2060, unknown aircraft and militarized sea vessels appeared at the Caesan coastal city of Brasten. Upon a battle put up by law enforcement, armed citizens, and local military, the invading forces overpowered the city. Shortly thereafter, the Dominion of Suchaz's flag was raised above. The following day, the Communist State of Darza declared it was under full invasion. Due to the reparations and restrictions put on the nation after the War Against Darza, the nation was stripped of its military prowess and power -- and thus was fully vulnerable to Suchaz's invasion.
Throughout the month of Sepreindus, more of Caesus fell under the control of Suchaz -- though its military and citizens heavily resisted. On Sepreindus XXI, Libertas also under invasion. By early Hallowtempora, Kasta and Moira were fighting off Suchese militants. Qascua faced invasion beginning on Hallowtempora XIII. By this point, most of Meristeppe had been thrown into sheer chaos, and due to this, the nation of Cesieteos offered small military support for Qascua, Moira, and Kasta. As the Suchese invasion force only became more prevalent, Legionnaire mercenaries had become contracted en masse by the Meristeppic nations.
From the months of Hallowtempora to Threshannual of the new year, Suchaz and its opponents waged war against one another. Darza had completely fallen to Suchaz. Also during this time, Suchaz had successfully entered the distraught nation of Vadrea, but was met with strong opposition by large criminal eminence grises. Domi Concordia's leader Alexander Dunwall sent a battalion to aid in pushing Suchaz out, as they had come close to entering Concordian territory.
In the early months of 2061, Suchaz also attempted to seize several small islands in Harbian territory. This resulted in severe backlash against the Dominion. At this point, Reuben Kale's grip on Meristeppe had slipped and remaining Suchese forces were in full retreat. Their failure to successfully conquer Meristeppe would quickly lead to a counter-invasion of their own nation in following weeks.
