They ordered their U-boats (Submarines) to attack all kinds of vessels that passes through the areas.

No matter, are they British boats or someone else’s.

German authority’s main target through the policy was to make the British government oblige to surrender the war.

On the 7th of May 1915, the German navy attacked and sank a British vessel ‘Lusitania’, where more than 1070 Britishers and 128 Americans lost their life.

They kept attacking other merchant boats also, where the majority were from the United States of America.

[Note: Because of the Great War, most of the factories in Europe were tied up, so at that time, America was exporting more quantities of goods to the continent. Either way, economically, it greatly benefited the country.]

This act of the German navy made America quite angry. 

Hence, at that time, the US president, Woodrow Wilson strongly warned Germany to stop attacking unarmed vessels without any warning.

In September 1915, Germany had to stop the policy due to the pressure from America and other neutral countries.


Why Germany Was Using Unrestricted Submarine Warfare Policy?

Germany had no deep rivalry with the United States, they just wanted to stop all the supplies that coming from other countries to Great Britain.

Germany wondered that their policy would make Great Britain weaker and they would be obliged to surrender finally.

But as they assumed, that didn’t happen.

Those actions from the German side started impacting negatively on the USA’s economy and the security of civilians.  

Therefore, finally, in the end, the US had to declare war on Germany on 2nd April 1917.

However, the Unrestricted Submarine Warfare policy was not the only cause, which lead to the U.S involvement in WW1.

There are also many other causes behind the USA’s decision.

The most important one was the controversial Zimmerman Telegram.

Yes, the Unrestricted Submarine Warfare policy by the German navy was an immediate cause of the United States’ entry into the First World War.

Along with this one, the Zimmermann telegram was also an important immediate factor of it.

If Germany had not done these two things, then America would probably never have been involved in the Great War.


What Was The Final Result of The US Entry Into The War?

The entry of the United States changed the final result of World War 1.

With the US arrival, the allies in the war became much more powerful.

On November 11, the year 1918, allies including Great Britain, France, the United States, Italy, Japan, and others declared victory over Central power.
