# Ruk (area)

Ruk (Egyptian Arabic: الروك) is a Coptic word, from Rosh (Coptic: ⲣⲱϣ), which means measuring the land in acres and valuing it, that is, estimating its degree of fertility in order to estimate the Kharaj on it. Today, ruk corresponds to the process of public surveying (real estate survey) and the process of tax assessment. In contemporary management terminology, it is called loosening and adjusting the reins.
Al-Maqrizi mentions the work of the ruk in the chapter “ذكر قبالات أراضي مصر”, in which he mentions the work of the Kharaj and how to collect it, so he mentions the following: “So when thirty years have passed, they change the year, and do ruk to the entire country, and adjust it in a new way, and add to what is possible for an increase without guaranteeing the country, and decrease In what needs to be reduced from it.” And in the same chapter: “So Al-Afdal Shahanshah addressed: about dissolving all the fiefdoms and do ruk to them, and he informed him that the interest in that would lie with the two fiefdoms and the Diwan because the Diwan obtains for him from these virtues a whole lot by which he obtains a desolate country, so he agreed to that and he dissolved all the feudal lordships and did ruk to them.”
The process of surveying lands was carried out in Egypt periodically due to the annual flooding of the Nile River. In Strabo's Geography, he mentions: “The Nile submerges the land, removing borders and changing appearances. It also does not reach the land, so it falls or the water remains in the low land, so it is not cultivated. As it is in some cases rise until it submerges new land and enters the scope of agricultural land.” As a result of this, the survey process becomes necessary to observe the changes occurring in agricultural areas and record them in the Diwan. Thus, the ruk results represent important documents for knowing the urban areas and agricultural units, as well as the classification of cultivated land according to the degree of its fertility and the amount of the Kharaj and the lesson prescribed for each unit.
The work of ruk was not limited to the lands of Egypt only, but it was also done in the lands of the Levant, as stated in “السلوك لمعرفة دول الملوك ”: “In it, the ruk of the Tripolitan kingdom was carried out by Sharaf al-Din Yaqoub, the supervisor of Aleppo, and its affairs were settled to welcome Ramadan in the year seven hundred and ten of Al-Hilali. Al-Kharaji to receive the maghl in the year seventeen. With this ruk, the fiefs of six Tabalkhana princes, and three fiefs of the Asharawat princes, were abolished, including wedding fees, prison fees, and other taxes, the amount of which was one hundred thousand dirhams and ten thousand dirhams each year. Sharaf al-Din presented the ruk papers to Cairo.”

## Al-Ruk al-Hossami

It is attributed to Sultan Al-Malik Al-Mansour Hossam al-Din Lajin of Egypt, and Al-Qalqashandi mentions the date of Lajin's work in Rajab Al-Fard in the year six hundred and ninety-seven AH. Ibn Iyas mentions that it began working on Monday, the sixth of Jumada al-Awwal, in the same year, and the person in charge of it was a Coptic official called “Al-Taj Al-Tawil”:
   "So he began to write lists of the areas of the lands and their names, and showed the results. He was tyrannical to the people, and the princes and the rest of the soldiers became fed up with him, and he became a no-nonsense friend. Some poets even said teasingly about him in poetry. The suburbs of Egypt at that time were divided into twenty-four qirats, of which four qirats were for the sultan, ten qirats for the princes and generals, and ten qirats for all the soldiers. So the Sultan decreed for the aforementioned Al-Taj al-Tawil that ten qirats would suffice for the princes and soldiers, and that the one who complained about the soldiers would be given an additional qirat, and thirteen qirats remained for the sultan. The soldiers complained about this and became upset.

Of the acreage, its crops, its fallow land, and what is in it of soil, trumpets, plantings, and trees, and the lesson of the area and what is on it for those who cut it, such as crops, chickens, sheep, clover, kiosk, cakes, and other types of hospitality.
