Creating Post-War Scenes: Part 1

Even after a war is over and done, the world isn't automatically perfect. There's still quite mess left to clean up. Every aspect of the countries involved (especially for the losers) is affected.

Economy
Wars aren't cheap. Each country has to pay for their armies. Uniforms, ammunition, and necessities have to be provided, usually at the expense of civilians.
The currency's value can also be decreased. Toward the end of the Roman empire, enemy looting and government spending of the state's gold made the value of Roman coins drop.

Boundaries
Land; you can't make more, what's there is there. Throughout the ages, countries’ borders have waxed and waned. Persia once stretched from India to Libya, all through the conquering of other nations.
So what land do the conquerors receive? How have the maps changed? What have the losers sacrificed?

Losers
Every war has a losing side, even if they do come to a agreement or sign a treaty.
They may be forced to give up land or money. Notably in ancient times, the victors could have them enslaved, such as the Babylonians, or revoke their rights, much as the Romans did to the Jews.
