What battleships were in World War 1?

There were exactly 104 dreadnought battleships existing during WWI; named after HMS Dreadnought which was launched in 1906. Prior to 1906, battleships are referred to as Pre-Dreadnoughts.

The first two Japanese Dreadnoughts are officially referred to as Semi Dreadnoughts, but they were clearly dreadnoughts as they had a uniform big gun 12" armament and turbine engines. I count them here as Dreadnoughts, because they should be.
