In his book, Yemeni civilization, Khazal Al -Majdi, confirms that this civilization was able to tame its geographical and climatic environment in favor of building an advanced agricultural base despite the fluctuation of its seasonal rains and the absence of rivers in it, and this pushed it towards the genius innovation to build the great dams, tanks and rock ponds, then control the torrential rains and rain and create an environment Fertile agricultural is guaranteed to provide most of the food of its people throughout the time of that civilization. Then, without the parts of the whole world, its land was granted the sources of incense, milk, lentum, bitter, perfumes and spices, so Yemen became the center of the commercial world in it, and this achievement gave it the opportunity to cross with the civilizations and peoples of the world. This first part of the Yemeni civilization describes, analyzes and discusses eight seasons equipped with references, tables and pictures, seven of which are for the elements of this civilization, which are elements (geographical, historical, political, legal, military, civil, economic), and is presented to them in a preliminary semester that is an entrance to Yemen and definition And with his studies references, scientists who worked to excavate its effects, write down and read his written inscriptions. The second part will deal with the rest of the elements of this civilization with a final chapter for its calibration and judgment and its achievements. In the second part of the book of Yemeni civilization, the image of this civilization is completed with nine new chapters, after the eight seasons of the first part, where it describes, discusses and analyzes eight elements of its civilization, which are the elements (intellectual, social, psychological, material, religious, scientific, artistic, moral) and concludes with a chapter For its evaluation and mentioning its unique achievements. Thus, we have presented, in the two parts, the full elements of the civilization that we used to present in our books on all civilizations. It must be said that the Yemeni person made a great civilization and was able to present, in one alloy, elaborate, the palaces, many parallels or contradictions that he collected with a rare genius, as it is a green civilization between deserts and seas, between kingdoms and tribes, and between cities and villages, and between ancient and monotheistic acts, and between Agriculture and trade, and between the yearning to expand its influence and contraction itself, a civilization that prevailed in a creative tension produced, in its controversy, new solutions that indicate the genius of its people and its ability to adapt and innovate. The book used the best and most academic scientific research, and the master's theses and doctoral theses on Yemen were helping us to present a scientific image of this civilization, and it made us completely move away from all religious and historical narratives because of its insecurity, and the effects were only our way to research, providing the book with the best We missed it from brief pictures, tables and definitions.
