Al-Hassan Ibn Zolaq was born in the age of the Ikhshidid state and saw with his own eyes its fall and the rise of the Fatimid state in Egypt, as well as the establishment of Cairo. So, he chose to be a historian of this period of Islamic Egypt. His grandfather is one of the famous scholars.
Although little was discovered of his own heritage, his histories gave evidence about his own skill, precision, perfect narration and good arrangement. The reason for his excellence is that he devoted his research to events of his own age and to those events he saw with his own eyes. He connected with witnesses of events and, finally, he presented events with credible descriptions. All this proved that he was an anthropological researcher because he used field techniques in his own research.
However, a complete book of his historical writing was not found. Some of his historical works were received by later historians and bore witness to his great efforts and to the appreciation he received.
His complete work was never found, except for a literary message in Egyptian Sybawei news. There were three books in historians' writings that were repeatedly attributed to Ibn Zolaq: Plans of Egypt, History of Egypt and Good Deeds of Egypt, as well as other books, such as the Biography of both Al-Ikhshidi and Al-Muizz Le-Din Allah Al-Fatimi.
We find both history and literature in his heritage, he also tried to be more specialized because he gave us the history of the era he lived in in an extensive way.
