Governments typically had been either unitary or confederated. Or another way to say that is that they either focused on centralized power (in someone like a king) or particularized power -- the power in the parts of a kingdom rather than at the center.
So, for instance, in France (prior to its Revolution), all the power in the kingdom centered in the hands of the king. For 175 years, they didn't even have a meeting of the Estates General which was their version of a representative body. And the power of nobles on their lands was reduced while the king's power grew.
Meanwhile, in the German territories, there was a loose confederation called the Holy Roman Empire. One of the kings or princes held the title of "emperor," but he really had no imperial power. The confederated German states retained control over their own kingdoms or territories.
The American experiment mixed something of the best of both approaches. There would be strong central power in the federal government, but putting checks and balances on that power by retaining certain aspects of control in the hands of the states within the union.
Know that this is from my memory but I learned about these recently. The crusades were to promote christianity. they did some good things like open up trade routes and introduce countries to each other but they also pillaged and killed those who would not convert.
The United States contributed to the conflict by providing military aid of $1–2 million per day to the government of El Salvador during the Carter and Reagan administrations and provided significant training.

The Mountains and Basins Region of Texas has lots of desert land, which almost makes it a complete opposite from the Gulf Coastal Plains. While the Gulf Coastal Plains has humid and moist coast lines with wet marshes, this region of Texas has dry and desert filled land.
