To protect territory from native Americans and prevent border violations by border thieves
I understand the war is the World War I. The assassination (of Austrian Crown Prince Franz Ferdinand) led to the Ultimatum (from Austria to the Kindom of Serbia) and the rejection of this ultimatum by Serbia led to Austria-Hungary declaring war (into which later other countries joined).
I'm just gonna make an educated guess here... and say... A?
Assyria was the region located in the ancient Near East which, under the Neo-Assyrian Empire, reached from Mesopotamia (modern-day Iraq) through Asia Minor (modern Turkey) and down through Egypt. The empire began modestly at the city of Ashur (known as Subartu to the Sumerians), located in Mesopotamia north-east of Babylon, where merchants who traded in Anatolia became increasingly wealthy and that affluence allowed for the growth and prosperity of the city.
According to one interpretation of passages in the biblical Book of Genesis, Ashur was founded by a man named Ashur son of Shem, son of Noah, after the Great Flood, who then went on to found the other important Assyrian cities. A more likely account is that the city was named Ashur after the deity of that name sometime in the 3rd millennium BCE; the same god's name is the origin for `Assyria'. The biblical version of the origin of Ashur appears later in the historical record after the Assyrians had accepted Christianity and so it is thought to be a re-interpretation of their early history which was more in keeping with their newly-adopted belief system.
The Assyrians were a Semitic people who originally spoke and wrote Akkadian before the easier to use Aramaic language became more popular. Historians have divided the rise and fall of the Assyrian Empire into three periods: The Old Kingdom, The Middle Empire, and The Late Empire (also known as the Neo-Assyrian Empire), although it should be noted that Assyrian history continued on past that point; there are still Assyrians living in the regions of Iran and Iraq, and elsewhere, in the present day. The Assyrian Empire is considered the greatest of the Mesopotamian empires due to its expanse and the development of the bureaucracy and military strategies which allowed it to grow and flourish.
