Heh. I didn’t know people were so simple. We’re just walking wallets.
Actually, economics play a role in lots of wars. Heinlein did say it was all about population pressure, but he was wrong.
Crusades: no economics at all. 1) Religious. 2) (the main part) second and third sons. They provided stability in that every family would have a ‘backup’ heir, but they provided instability in that they were given military training then let loose with no responsibilities. They ran around killing and raping, or just getting drunk and gambling in the streets. The Crusades were, to a large degree, made up of those sons.
American Revolution: Yes, largely economic. America may not have been getting hammered by taxes quite as bad as the brits, but they were unhappy about it. It was an economic stimulus that motivated a more basic urge. The colonies were populated by, surprise! colonists. Those people who, for whatever reason, left the comforts of a populated land and went to carve a home out of the wilderness, people who had grown up burying almost as many children as they saw grow up. Theirs was a very individualist inclination, NOT something that tolerates any sort of government.
The post revolution trouble: after the revolution, it was quite some time before our country was stable. It faced most of the problems that see post-revolution governments. Money, and people wanting their own piece of the pie. THere were many conflicts, including washington taking the provisional government’s army out and putting down another rebellion or three. Shay’s Rebellion was economic. The farmers of the NE were upset about losing money. Others were about power “Why should THEY be the ones to run the government?” and “I should be the man on top”.
The war of 1812: Partly economic (trade matters), partly bad feelings stemming from the previous war (around 1780.
The Mexican War: Expansionism/ economic. American pride + Mexico has valuable land = America wants that land
The Civil War: A very complex milieu. If you study the history of every nation, you will see a trend towards centrilization of power. Europe went, in all nations, from an aristocratic form of governance (lords are kings in their own right), to some form of monarchy. And it’s doing it again, with all the nations struggling to come together in a unified Europe. Japan went from the Shogun Lords to the Empire. America went from more powerful states to a more powerful federal government. States rights WAS a large part of that war, the economics of it was important too, though. It was about power, it was about money. Slavery wasn’t as large a role as most would have you believe. The nation was centralizing power, and the powers of the South saw their portion getting smaller, so they made their own nation, where their power would be no lesser, even greater. Power was, I believe, more important than economics in that war. Not even so noble a calling as “states’ rights”, just people in power wanting to keep their power.
I don’t know about the war in Cuba in 1896
WWI: We were mostly isolationist in 1919. We didn’t have too large an economic stake in Europe. We could have cut off our trade with them without too much loss. Our entry into that war was mostly a result of internal powerplays. I think President Wilson saw that America could become a powerful world player, but not if it had to work with a German-dominated Europe. After that war America drew back into its shell, only slightly more open than before.
WWII: The war did pull us out of the Depression. I don’t think any politician went into that war thinking “I’ll send American boys over to die so we can pick up the economy” though. We didn’t have economic interests to protect in Europe. Hell, we barely had interests to protect in AMERICA.
I don’t know enough about modern wars to comment.
