when did italy enter the first world war by declaring war against austria-hungary?
23 may 1915
after italy had entered world war i by declaring war on austria-hungary on 23 may 1915, germany felt treaty-bound to support the austrians in attacks against italian ships, even though germany and italy were not officially at war. as a result, german u-boats operating in mediterranean were assigned austro-hungarian numbers and flags. in some cases the same austro-hungarian numbers were assigned to different german u-boats. after 28 august 1916, when germany and italy were officially at war, the practice continued, primarily to avoid charges of flag misuse. the practice was largely ended by 1 october 1916 except for a few large u-boats that continued using austro-hungarian numbers.

when austria-hungary found itself at war in august 1914 with the rival triple entente, italy proclaimed its neutrality, considering austria-hungary the aggressor and defaulting on the obligation to consult and agree compensations before changing the status quo in the balkans, as agreed in 1912 renewal of the triple alliance. following parallel negotiation with both triple alliance, aimed to keep italy neutral, and the triple entente, aimed to make italy enter the conflict, italy declared war on austria-hungary.
