When Sindh was occupied by British army and was annexed with Bombay, governor of the province Sir George Clerk ordered to make Sindhi the official language in the province in 1848. Sir Bartle Frere, the then commissioner of Sindh, issued orders on August 29, 1857 advising civil servants in Sindh to qualify examination in Sindhi. He also ordered Sindhi to be used in all official communication. Seven-grade education system commonly known as Sindhi-Final was introduced in Sindh. Sindhi Final was made a prerequisite for employment in revenue, police and education departments.
