The matchlock is a type of gunlock (a device for igniting the charge of a firearm) in which powder is ignited by a match. It was the first mechanism that facilitated the firing of a firearm.
The matchlock was invented in the Ottoman Empire around 1425 as there is evidence of them using the arquebus (a portable long gun) around that time. Here is a photograph of a matchlock firearm and an animation depicting the working of a basic matchlock:
