Why sumerians were attacked by outsiders

Essentially, anatomically, the reproductive organs of the human and that of animal are not compatible. While humans can mate all year long, other female mammals have an estrous cycle.

It only happens once a year. In type C ESSs, females evolve perfect choosiness and males mate randomly. This occurs only when females imprint on their fathers.

Ben Davis February 29, Why did the Sumerians fight each other?

What were Sumerian cities protected by? Who did the Sumerians fight? Why was Sumer a challenging place to live? What was the Sumerians biggest problem? Spears and rocks thrown by slingshots filled the air and many more died. Apparently, the army with the most men still standing won the day. This was the typical battle order of the times. A stele raised by the king of Lagash commemorates the victory of that city over its neighbor and enemy city, Umma.

The Stele of Vultures shows ranks of soldiers in a phalanx formation, armed with spears and wearing copper helmets and short, armored cloaks for protection. The king of Lagash rode to the battle in the chariot of the times—a clumsy, heavy cart pulled by four onagers, or semi-wild asses. Sumerian military innovation includes the chariot, helmet, armored cloaks, bronze axes and the phalanx formation in battle. Sargon of Akkad created the first empire through conquest.

As armies grew larger, the need for competent administration and logistics grew in importance. Made of wood, horn and animal sinew laminated together, the composite bow had two to three times the power of a simple wooden bow. Homes were constructed from bundled marsh reeds or mud bricks, and complex irrigation canals were dug to harness the silt-laden waters of the Tigris and Euphrates for farming. Major Sumerian city-states included Eridu, Ur, Nippur, Lagash and Kish, but one of the oldest and most sprawling was Uruk, a thriving trading hub that boasted six miles of defensive walls and a population of between 40, and 80, At its peak around B.

Even though they shared a common language and cultural traditions, the Sumerian city-states engaged in near-constant wars that resulted in several different dynasties and kingships.

The first of these conflicts known to history concerns King Eannatum of Lagash, who defeated the rival city-state of Umma in a border dispute sometime around B. Under Eannatum, Lagash went on to conquer the whole of Sumer, but it was just one of several city-states that held sway over Mesopotamia during its history. The infighting led to several military advancements—the Sumerians may have invented the phalanx formation and siege warfare—but it also left them vulnerable to invasions by outside forces.

During the latter stages of their history, they were attacked or conquered by the Elamites, Akkadians and Gutians. A clay seal depicting beer drinking in a banquet scene dating from B. Credit: E. Archaeologists have found evidence of Mesopotamian beer-making dating back to the fourth millennium B. The brewing techniques they used are still a mystery, but their preferred ale seems to have been a barley-based concoction so thick that it had to be sipped through a special kind of filtration straw.

In its most sophisticated form, it consisted of several hundred characters that ancient scribes used to write words or syllables on wet clay tablets with a reed stylus.
