Question: When was the kingdom lying immediately to the north of the region prevailing with "Near East" disgrace and the region having the most growth in desalination for agricultural use created?

Knowledge 1: Near East
Subsequently with the disgrace of "Near East" in diplomatic and military circles, "Middle East" prevailed. However, "Near East" continues in some circles at the discretion of the defining agency or academic department. They are not generally considered distinct regions as they were at their original definition. [SEP] Knowledge 2: Water resources
Desalination is an artificial process by which saline water (generally sea water) is converted to fresh water.  The most common desalination processes are distillation and reverse osmosis.  Desalination is currently expensive compared to most alternative sources of water, and only a very small fraction of total human use is satisfied by desalination. It is usually only economically practical for high-valued uses (such as household and industrial uses) in arid areas. However, there is growth in desalination for agricultural use, and highly populated areas such as Singapore or California. The most extensive use is in the Persian Gulf.

The Kingdom of Saudi Arabia is a country situated in Southwest Asia, the largest country of Arabia, bordering the Persian Gulf and the Red Sea, north of Yemen. Its extensive coastlines on the Persian Gulf and Red Sea provide great leverage on shipping (especially crude oil) through the Persian Gulf and Suez Canal. The kingdom occupies 80% of the Arabian Peninsula. Most of the country's boundaries with the United Arab Emirates (UAE), Oman, and the Republic of Yemen (formerly two separate countries: the Yemen Arab Republic or North Yemen; and the People's Democratic Republic of Yemen or South Yemen) are undefined, so the exact size of the country remains unknown. The Saudi government estimate is at 2,217,949 square kilometres, while other reputable estimates vary between 2,149,690 and 2,240,000 sq. kilometres. Less than 1% of the total area is suitable for cultivation, and in the early 1990s, population distribution varied greatly among the towns of the eastern and western coastal areas, the densely populated interior oases, and the vast, almost empty deserts.

For much of the region's history a patchwork of tribal rulers controlled most of the area. The Al Saud (the Saudi royal family) emerged as minor tribal rulers in Najd in central Arabia. From the mid-18th century, imbued with the religious zeal of the Wahhabi Islamic movement, they became aggressively expansionist. Over the following 150 years, the extent of the Al Saud territory fluctuated. However, between 1902 and 1927, the Al Saud leader, Abdulaziz, carried out a series of wars of conquest which resulted in his establishing the Kingdom of Saudi Arabia in 1930.

Parallel with the growth of specialized agencies for conducting or supporting statescraft in the second half of the 20th century has been the collection of resources for scholarship and research typically in university settings. Most universities teaching the liberal arts have library and museum collections. These are not new; however, the erection of these into "centres" of national and international interest in the second half of the 20th century have created larger databases not available to the scholars of the past. Many of these focus on the Ancient Near East or Near East in the sense of Ancient Near East.

Answer: 1930
