The Kalhora (Sindhi: ڪلهوڙو) is a Sindhi Sammat clan in Sindh, Pakistan.^[2][3][4]

According to the natives of Sindh, the word Kalhoro originates from the (Sindhi: ڪَلھو/ Kalho) meaning Alone.^[5]

Although the Kalhoras claim Arab Abbasi origin, it has been refuted.^[4] And according to Sarah Ansari, they were likely Jamot who had lived for many years in what are now the districts of Shikarpur and Larkana in Sindh. She traces their origin to a religious mendicant of the 16th century, called Adam Shah Kalhoro, and says that the legitimacy which his religious role gave to them was significant in their subsequent veneration by many Sindhi inhabitants.^[6]

With Kalhora success in taking control of lands from local zamindars, the Delhi Sultanate eventually considered it necessary to put a stop to the growing power. After defeating them, the Sultanate brought them inside the fold by offering an amnesty, recognising that the Kalhoras were widely respected in the province. This process resulted in the Kalhora leader around the start of the 18th century, Yar Muhammad Kalhora, being appointed subedar of the Upper Sindh area and holding the title of Khuda Yar Khan. His son, who succeeded to the position in 1719, was granted further areas of control such that virtually all of Sindh came under the control of what was now the Kalhora dynasty. The dynasty retained its role, in large part by balancing the interests of influential Sindhi groups such as sufis and Balochs, when the Sultanate lost control to the Persian Afsharid dynasty, and again when the Persians were supplanted by the Afghan Durranis. The amount that was paid as tribute to their overlords gradually reduced. Kalhora control of the area eventually came to an end when they were challenged by what became the Balochi Talpur dynasty.^[6]
