A breech-loading swivel gun was a particular type of swivel gun and a small breech-loading cannon invented in the 14th century. It was equipped with a swivel for easy rotation and was loaded by inserting a mug-shaped device called a chamber or breech block, filled with gunpowder and projectiles. It had a high rate of fire, as several chambers could be prepared in advance and quickly fired in succession and was especially effective in anti-personnel roles. It was used for centuries by many countries of Europe, Asia and Africa.
