This period is generally taken to coincide with a major shift in population from southern Mesopotamia toward the north. Ecologically, the agricultural productivity of the Sumerian lands was being compromised as a result of rising salinity. Soil salinity in this region had been long recognized as a major problem. Poorly drained irrigated soils, in an arid climate with high levels of evaporation, led to the buildup of dissolved salts in the soil, eventually reducing agricultural yields severely. During the Akkadian and Ur III phases, there was a shift from the cultivation of wheat to the more salt-tolerant barley, but this was insufficient, and during the period from 2100 BC to 1700 BC, it is estimated that the population in this area declined by nearly three fifths.[24]This greatly weakened the balance of power within the region, weakening the areas where Sumerian was spoken, and comparatively strengthening those where Akkadian was the major language. Henceforth Sumerian would remain only a literaryand liturgical language, similar to the position occupied by Latin in medieval Europe.
Following an Elamite invasion and sack of Ur during the rule of Ibbi-Sin (ca. 1940 BC), Sumer came under Amorites rule (taken to introduce the Middle Bronze Age). The independent Amorite states of the 20th to 18th centuries are summarized as the "Dynasty of Isin" in the Sumerian king list, ending with the rise of Babylonia under Hammurabi ca. 1700 BC.
The swing era came to an end due to several factors, including the shift in musical tastes towards bebop and other jazz styles, as well as the impact of World War II on the music industry. The economic strain of the war led to a decline in big bands and the rise of smaller ensembles, further contributing to the decline of the swing era.
Sharks are considered endangered due to overfishing, habitat destruction, and climate change impacting their populations. These factors have led to a decline in shark numbers, disrupting marine ecosystems and increasing their risk of extinction. Conservation efforts are being made to protect and restore shark populations.
The most important factor leading to Alexander the Great's eventual decline was the vastness of his empire, which led to overextension and difficulty in managing such a large territory. Additionally, the lack of a clear successor and infighting among his generals after his death contributed to the fragmentation of his empire.
LED light bulbs should last around 15,000 to 50,000 hours. Factors that can affect their lifespan include the quality of the bulb, usage patterns, operating temperature, and electrical fluctuations.
These populations would be classified as different species. Geographic isolation has led to reproductive isolation, causing them to evolve independently and become unable to produce viable offspring together.
3 factors that led to the end of feudalism was the bubonic plague, the hundreds' years war, and the magna carta
