Honestly, not really. At least not in any way that you can definitively track.

The sinking was huge news all over the world- the full effects of which we'll never be able to fully understand or quantify. Many rich, influential, and famous people died, over 7 million letters and tons of cargo (jewelry, rare art, and yes- a car) were lost, and it shattered what (up to that point) had been a largely unquestioned trust in technology.

If you subscribe to the "butterfly effect" viewpoint on history- there is absolutely no telling how different things would be if the Titanic hadn't sunk that night.

But if you're wondering if there are any direct connections between the Titanic and the start of WW1- no.

On a side-note both of it's sister ships were conscripted into service during the war. The Britannic was used as a hospital ship and was sunk by a mine in the Mediterranean in 1916. It was the largest ship to sink during WW1. The Olympic was used a troop transport- they gave it a really wild "dazzle camouflage" paint job and it even sunk a German U Boat by ramming it. After the war it returned to normal service and had a long career until it was decommissioned in the mid 1930s.

Here is a picture of the Britannic and Olympic during their WW1 years.
