When were guns first used in Europe?

Answer 1

Gunpowder came to Europe in the late 13th century. The first guns appeared along side. To clarify your question, 'gun' can refer to either artillery/cannons or small arms. The first small arms (i.e. hand cannon) appeared in the 14th Century.

Records show that Gunpowder was being made in the Tower of London from as early as 1346.

1200's.
