Endowments of Eyüp Sultan Mosque: History, Legacy & Records

The Endowments of Eyüp Sultan Mosque, nestled in Istanbul's historic Eyüp district, transcends its role as a mere place of worship. Indeed, it has served as a vibrant hub of civilization, culture, and faith for centuries. To truly grasp the historical and environmental evolution of this iconic structure, examining the Eyüp Sultan Camii vakfiyeleri (endowment deeds) and land registry records is crucial. These documents meticulously detail the lands, income sources, and social functions of the mosque from its initial construction to the present day. As we navigate 2026, these endowment deeds remain invaluable resources for tracing the past and understanding the intricate social and economic fabric of that historical period.

The Historical Process and Importance of the Endowments of Eyüp Sultan Mosque

Fatih Sultan Mehmed commissioned the construction of Eyüp Sultan Mosque immediately following the conquest of Istanbul. From its inception, in keeping with the ancient tradition of endowments, various properties were dedicated. This ensured a continuous income stream, thereby guaranteeing its sustainability. Consequently, these endowment deeds enabled the mosque to operate not solely as a religious center, but also across numerous other domains, including education, healthcare, and social assistance. The Endowments of Eyüp Sultan Mosque played a pivotal role in this.

Endowment deeds represent a cornerstone of the Ottoman legal system and social structure. Moreover, their preparation reflects the bureaucratic processes, economic interactions, and societal priorities of the era. Critically, reviewing these documents today in 2026 offers profound insights into the lifestyle, property law, and philanthropic ethos of that historical period.

Contents of the Initial Endowment Deeds

• Founding Endowment Deed: This foundational deed, created during the mosque's establishment, specified key immovable properties and designated the first administrators. Typically, it encompassed structures like an imaret (public soup kitchen), madrasah (religious school), and hammam (bathhouse), alongside the mosque itself. These initial Endowments of Eyüp Sultan Mosque laid the groundwork for its future.
• Sources of Income: The early endowment deeds meticulously cataloged farms, shops, inns, and various lands intended to generate income for the mosque. All properties listed were specifically allocated to cover the operational expenses of the mosque and its associated institutions.
• Officials and Salaries: Furthermore, these deeds detailed the duties and salaries of mosque personnel, including imams, muezzins, preachers, trustees, and other employees. This provides valuable information regarding the employment structure of the time.

Eyüp Sultan Mosque's Land Registry Records and Boundaries

Land registry records, which can be viewed as an extension of endowment deeds, are official accounts documenting changes in ownership, land boundaries, and property values around the mosque. These records illuminate not only the land and buildings owned directly by the mosque but also the locations of other endowed immovable properties. Therefore, in 2026, the information gleaned from these records allows for a clearer understanding of Eyüp district's urban development over centuries, directly linked to the Endowments of Eyüp Sultan Mosque.

Crucially, land registry records supply significant data that also informs modern urban planning. Past land use patterns, property demarcations, and relationships with adjacent parcels form the underlying structure of today's settlement fabric.

Cadastral Survey Registers and Cadastre

• Cadastral Survey Registers (Tahrir Defterleri): These registers from the Ottoman period contained comprehensive population censuses and land records. They provided detailed information on the size, boundaries, and intended use of lands owned by mosque endowments.
• Cadastral Works: Through modern cadastral surveys, endowed lands have been accurately mapped onto current plans, and their boundaries finalized. This process helps ascertain the precise current location of properties originally included within the scope of the Endowments of Eyüp Sultan Mosque.

These records also elaborated on the ownership status of numerous structures surrounding the mosque, such as fountains, public water dispensers (sebil), educational institutions, roadways, and even cemeteries. Consequently, it becomes evident that the mosque complex functioned as a living, integrated center, beyond merely a place of worship. This integrated approach profoundly influenced Socioeconomic Transformations and Regional Impacts of Eyüp Sultan Mosque in 2026.

The Social and Economic Impact of Endowment Deeds

The Endowments of Eyüp Sultan Mosque are far more than simple inventories of immovable property; they provide profound insights into the social and economic life of their respective periods. Through these deeds, students attending madrasahs affiliated with the mosque received covered accommodation and meals, hospitals were established to care for the sick, and aid was extended to those in need. This vividly illustrates how endowments formed the very backbone of the Ottoman society's commitment to philanthropy and social justice.

From an economic standpoint, endowments represented one of the largest concentrations of capital during the era. Endowed shops, inns, and lands continuously provided financial support to the mosque through rental income, thereby fostering economic dynamism. Furthermore, the very act of establishing an endowment significantly influenced the shaping of inheritance law to some degree.

Services Provided Through Endowments

The endowment deeds clearly reveal that the mosque served as a comprehensive social hub, extending far beyond its religious function. The array of services provided is remarkably extensive, all supported by the Endowments of Eyüp Sultan Mosque:

• Education: Students in madrasahs were supplied with accommodation, food, and robust educational opportunities.
• Healthcare: Patient care was diligently provided in hospitals (şifahane) and mental asylums (bimarhane).
• Social Solidarity: Food distribution to the less fortunate (imarets) and vital support for orphans and widows were consistently provided.
• Infrastructure: Essential infrastructure services, such as the construction and ongoing maintenance of fountains, bridges, and roads, were also financed through these endowments.

These crucial services were all funded by income streams meticulously detailed within the endowment deeds. Thus, the mosque developed into a sanctuary, a center for learning, and a guiding hand for the surrounding community.
