He served as the wali (governor) of the Sidon and Damascus eyalets (provinces) in the early 18th century.
In Damascus, Osman Pasha (known by the Damascenes as "Abu Tawq")[1] served twice in 1719-1721 and 1723-1725,[2] and was known to be a particularly oppressive governor, who, with the use of his paramilitary forces, extorted the inhabitants of the city and its countryside.
[2][4] Osman Pasha governed both provinces in his last term, but resided in Sidon and entrusted the administration of Damascus with a deputy governor.
[5] Damascene anger towards his heavy-handed rule precipitated a popular revolt led by the Hanafi mufti, Khalil al-Bakri, which ultimately led to Osman Pasha's dismissal from the governorship of Damascus;[3][5] al-Bakri persuaded Sultan Ahmed III that Osman Pasha was unfit to govern the city.
[4] His son Ahmed Pasha later served a second term as governor of Sidon in 1730-1734.
