As in Rise of Nations, the Library is the nucleus of your scientific research (or what passes for it) in Warbirth.

There are five paths of research in the Civic Centre: Science Science, Commerce Commerce, Administration Civic.jpg, and Military Militiae.jpg, as well as three trunk technologies. Each one of them is a prerequisite for further research, which in turn might contribute towards bettering your units and even the stylistic appearance of your faction's buildings!

Note that the Library's appearance and nomenclature can change depending on the submods. While Age of Chariots and Rise of the Ancients use a Library, Age of Empires relegates its functions to the Civic Centre.

Ages Age.png[edit | edit source]

"[T]hey pass away in the rustling blast, and other leaves lift their green heads on high." —James Scott MacPhearson, Ossian

Ages allow your faction to grow and mature as a civilisation, and are required to access Reforms and Research which enhance your faction vis-à-vis others. Each age is costlier and harder to research than the next, but great are the rewards should you chooise to pursue them.

Scientific research Science[edit | edit source]

If you search for the laws of harmony, you will find knowledge. —Egyptian saying

Science research increases line of sight for many of your units (including buildings), makes new Resource technologies available so you can increase gather rate, permits construction of new types of buildings, and decreases the cost of all other technology research incrementally.

Commerce research will cost you Timber and Knowledge at the Library. When you complete Commerce research, your [1]goes up for all Resources you gather: Food, Timber, Metal, and Wealth. You can gather more of them only up to the Commerce Cap; surpass the cap and any excess is simply lost to you.

In addition, Commerce is required in order to open up access to Mercenaries. While there are several exceptions, Mercenaries unlock at Lvls 1,3 and 5.

Administration research Administration[edit | edit source]

To bring about the rule of righteousness in the land, so that the strong should not harm the weak.
—Hammurabi's Code; Prologue

Administration research allows you to build one new city with each completed round, and increases your national borders. If your borders abut other nations' borders, then you'll gain strength in the pushing match. As long as you don't touch other factions' territories yet, the diameter of area covered by your borders centred around your Cities simply expands with each level attained. Administration research is also required to gain access to a variety of military units as well.

In addition, unlike the vanilla game or previous mods, Agronomics Agronomics research in Warbirth relies heavily on Administration, not Science.

Military research[edit | edit source]

"Thou leadest as a warrior king thine army's wings what time thou comest in the van of these swift streams."
Rig-Veda (m. 10, hymn LXXV)

Completing Military research increases your population cap and also allows you to start upgrading your units at your military structures. Additionally, the cost of units and unit upgrades is lowered with each successive level researched.

While Warbirth continues to showcase population caps in multiples of 50 (as opposed to 25 in vanilla Rise of Nations), Warbirthslows down your ability to research higher level Military research owing to its nature as a Bronze Age mod.

After level 3, :

  • Level 4: x 2 length.
  • Level 5: x 3 length
  • Level 6: x 5 length
  • Level 7: x 7 length

Most likely it will be a senate-sized building. All buildings for this one are ready.
