Bashir Shihab II was a Lebanese emir who ruled the Emirate of Mount Lebanon in the first half of the 19th century. Born to a branch of the Shihab family which had converted from Sunni Islam, the religion of previous Shihabi emirs, he was the only Maronite ruler of the Mount Lebanon Emirate.

The siege of Acre of 1799 was an unsuccessful French siege of the Ottoman city of Acre and was the turning point of Napoleon's invasion of Egypt and Syria, along with the Battle of the Nile. It was Napoleon's third tactical defeat in his career, being defeated at the Second Battle of Bassano and the Battle of Caldiero three years previously during the Italian campaign, and his first major strategic defeat, along with the last time he was defeated in battle for 10 years. As a result of the failed siege, Napoleon Bonaparte retreated two months later and withdrew to Egypt.
