Along the ancient Hajj routes, people witnessed benefits for themselves in their trade, the transfer of cultures and knowledge, and their impact on the social fabric of the communities located along those paths, forming bridges of communication between Islamic countries. The pace of movement during the past centuries was prosperous on these paths, and their use was not limited to the purpose of Hajj, but travelers used them throughout the year to reach a destination, and they crossed them to take care of their needs and affairs. Bahrain is one of the Islamic countries from which Muslims depart every year during the Hajj months, heading to Mecca to perform the Hajj pilgrimage.  .Given the importance of this period in the history of the Arabian Peninsula in general, I sought God’s help and studied the services of Bahraini pilgrims during the twelfth century AH/eighteenth century AD, meaning that the 12th century AH/18th century is the time frame for the study, the subject of which is the services of Bahraini pilgrims, and thus the spatial frame is the company of the Bahraini pilgrims, and it was possible to address this research through the following elements: First: The Bahraini Hajj Route to Mecca, its description, and its stations. Second: Water and food services on the Bahraini Hajj Route during the 12th century AH/18th century CE. Third: Security services on the Bahraini Hajj Route during the 12th century AH/18th century CE. Fourth: The efforts of the First Saudi State in serving Bahraini Hajj pilgrims. Fifth: The hosting of Bahraini Hajj pilgrims by the Imams of the First Saudi State. Sixth: Markets and commercial facilities dedicated to serving Bahraini Hajj pilgrims. I followed all of these elements with a conclusion that summarized the study's findings, which I appended to my research. This is in addition to a list of approved sources and references.
