Why did Britain join the Triple Entente?

Answer 1

Britain had a commitment to backing the neutrality of Belgium, so when Germany invaded Belgium to get to France (an approach laid out in the Schlieffen Plan) Britain felt forced to declare war.

Britain was also caught, as was the rest of Europe, in the popular romanticism of war that made many Europeans eager for war when it came.

Answer #2

Britain saw two opportunities in the war. The first was to curtail German industrial output, its main competitor, which threatened Britain's dominance of international trade and shipping, and the second was to seize the oil-rich resources of the Ottoman Empire. Within three months of declaring war against Germany, British troops were marching into Basra, thousands of miles away from Belgium.

Answer 2

Britain joined the Triple Entente with France and Russia to counter the triple alliance of Germany, Austria-Hungary and Italy. The increase of Germany threat in the United Kingdom forced Britain to end its Splendid Isolation.

Answer 3

At the end of the Napoleonic wars, Britain had made a treaty to defend Belgium if they were invaded by any other country. When the Germans invade Belgium in 1914 the British had no choice but to declare war on Germany.
In world war one, everyone was part of an alliance. When Austria Hungary (and yes, I find this entire chain necessary) declared war on Serbia for assasinating Archduke Ferdinand, Russia declared war on Austria Hungary, and Germany in turn declared war on Russia, as Austria Hungary's ally. France declared war on Germany and Austria Hungary, because the French were allied with Russia. Now Germany knew they couldn't just make a direct shot into France, so they went through the lowlands, with Belgium and the Netherlands. Great Britain said that they would attack Germany if they violated Belgium's neutralty, which they did to invade France. That's how Britain was sucked into World War 1.

Answer 4

Britain joined WWI due to the fact that it's two greatest allies (France and Russia, who made up the Triple Entente) were fighting with Austro-Hungarian Empire and Germany the "Central Powers" later joined by the Ottoman Empire.

These chains of alliances were supposed to prevent a war but infact dragged more and more nations into it.

Austria declared war upon Serbia after a terrorist attack, Russia came to Serbia's defence, Germany mobilised to assist Austria and invaded Belgium - in a preemptive strike at France, France came to help Russia (and get revenge for the 1870 war) and Britain came in to help France (and protect Belgium, and reduce German influence). Various other minor powers slowly joined both sides (mainly the Entente) and The Ottoman Empire joined the Central Powers.

So Britain joined WW1 technically to protect Belgium and in reality to honour agreements with France and Russia. There was also an unspoken need to "take Germany down a peg".

Answer 5

Russia was a bit scared/surprised in the growth of the German army and so formed the TRIPLE entente for protection/support.

Answer 6

To ensure that war never broke out again, this was to be accomplished through the policy of collective security and disarmament.
