The history of pre-mandate Palestine has been underexplored, leaving "entire centuries, whole social groups, and a wide range of fundamental issues... obscure" (Doumani, 1995). This paper aims to illuminate the intellectual and social history of early 19th-century Palestinian society through the writings of Hasan al-Husayni (d. 1811), a prominent Muslim scholar who served as Mufti of Jerusalem for almost 30 years. Unlike previous studies that heavily rely on court records, particularly in investigating the social history of Palestine (e.g., Doumani, 1990, 2017; Tamari, 2008; Tucker, 1988, 2008), this paper examines two other types of sources to explore the social and intellectual history of 19th century Palestine. Hasan al-Husayni left behind two books that constitute rich sources: his collection of fatwas and his biographical work. Following the precedent set by previous studies (e.g., Powers, 1990; Masud, 2009; Skovgaard-Petersen, 1997; Benzing, 1977), fatwas can provide us with a rich source of both social and intellectual history. They include conversations between laypeople seeking advice and scholars responding with references to Sharia sources. These questions and answers, as found in al-Husayni's fatwa collection, provide insight into social practices in early 19th-century Palestine and show colloquial language used by the laypeople. Furthermore, al-Husayni authored a book of biographies of Jerusalemite scholars from the 18th and early 19th centuries. His work not only provides biographical information about these scholars but also illustrates the scholarly relationships between Jerusalemite figures and other scholars in the Muslim world. It elucidates the teacher-student relationships among scholars and the travel undertaken by scholars to and from Jerusalem, shedding light on the cultural and social connections between Palestinian society and other societies in the region. By delving into the multifaceted sources provided by al-Husayni, this paper constructs the network of relationships between scholars from Jerusalem and those from other regions in the Islamic world. It argues that Jerusalem served as a scholarly center during the Ottoman period, fostering robust intellectual connections with other centers across Egypt, Syria, and North Africa. Additionally, the paper offers insights into early 19th-century Palestinian society and emphasizes the significance of new historical materials in enriching our understanding of social and intellectual dynamics in Palestine.
