Unrestricted Submarine Warfare in WWI

Unrestricted submarine warfare involves submarines sinking vessels without warning, contrary to prize rules that require submarines to surface and ensure the safety of merchant crews before sinking their ships. This tactic was notably used by Germany during WWI and WWII, leading to significant naval campaigns and influencing the entry of countries like the United States and Brazil into the wars. Despite attempts to regulate submarine warfare through treaties, the arming of merchant ships and their role as naval auxiliaries rendered such regulations ineffective. The tactic aimed to blockade countries reliant on merchant shipping, impacting global naval strategies.
