The New Union evaluates its financial situation and deems it both monetarily sound and economically beneficial to invest funds in improved roads, and to dig a series of cbrown towns through Eastern Avalonia linking to Sea or Ormica with the Utesian Ocean which will more easily allow valuable goods to flow into and out of the Britonic States and the Saxon League. The New Union has enough cash lying around from centuries of budget surplus to accomplish much of this work.
The New Union's taxation system undergoes scrutiny, and is altered such that tariffs are extremely low (or meet foreign ones) to facilitate trade, and many things become taxed a pittance while other things are taxed less. Ultimately, this decreases taxes for the poor as they consume a less broad range of goods, while the rich pay slightly more, but not so much as to cause disturbance. All told, even counting in funds set aside for public works projects, including the construction and maintenance of city walls in provincial capitols, the New Union's budget bears a surplus (less than under the previous system of taxation, but still a fair chunk of change as a result of wiser spending and revenue from the newer provinces).
A campaign is waged in the new Union's military forces to reward competent soldiers and officers and demote and improve the less competent. The New Union's conscription policy is changed to allow a wider range of opportunities of those who fulfill their mandatory year of service, and to better encourage and incentivise those deemed promising to remain with the military. The military representative in the new Union High Command completes a comprehensive series of essays entitled "Auf Krieg und Sieg" (Of War and Victory) on strategic, economic, logistical, tactical, political, technological, social, and preparatory aspects of war. The book is kept secret as it is some really good stuff that cannot fall into the hands of any enemies of the New Union. The New Union's military receives orders that every six months for the next decade, the armed forces will be readied for action and inspected so as to encourage alertness in the ranks.
