What was the last major battle between galley type ships and who was it between?

The Swedish and Russians used galley ships during the sea battle at Svensksund in 1790,I'm not sure if this the battle you are thinking of.

P.S It's good to have you back Kwll,you've been missed. (But I see you're making up for lost time!)

Hi Viv, great to see you too. Sorry, not the one I was looking for, this one had an impact on world events and had a large number on each side.

For much of the 16th century the Mediterranean was a battleground between Christians and Muslims. A decisive battle between two large galley fleets was expected to decide the fate of the entire Mediterranean basin. In August 1571, an Ottoman fleet of some 235 galleys encountered the slightly smaller Christian fleet of the Holy League. In a five hour melee the Christians inflicted a decisive defeat on the Turks. Lepanto was the last great galley fight of all time and one of the most decisive naval battles in history.
