What happened September 1914 AD

In September 1914, Redmond encouraged the Volunteers to enlist in the British Army, a faction led by Eoin MacNeill broke with the Redmondites, who became known as the National Volunteers, rather than fight for Britain in the war.

Von Kluck (German Leader) used this freedom to disobey orders, opening a gap between the German armies as they closed on Paris. The French and British exploited this gap to halt the German advance east of Paris at the First Battle of the Marne from 5 to 12 September and push the German forces back some 50 km (31 mi).

On 5 December 1914, Mussolini denounced orthodox socialism for failing to recognize that the war had made national identity and loyalty more significant than class distinction. He fully demonstrated his transformation in a speech that acknowledged the nation as an entity, a notion he had rejected before the war.

In September, Churchill assumed full responsibility for Britain's aerial defense.

After the First Battle of the Marne (5–12 September 1914), Allied and German forces unsuccessfully tried to outflank each other, a series of manoeuvres later known as the "Race to the Sea". By the end of 1914, the opposing forces were left confronting each other along an uninterrupted line of entrenched positions from Alsace to Belgium's North Sea coast.

The British Parliament passed the Third Home Rule Act on 18 September 1914 with an amending Bill for the partition of Ireland introduced by Ulster Unionist MPs, but the Act's implementation was immediately postponed by the Suspensory Act 1914 due to the outbreak of the First World War in the previous month. The majority of nationalists followed their IPP leaders and John Redmond's call to support Britain and the Allied war effort in Irish regiments of the New British Army, the intention being to ensure the commencement of Home Rule after the war.

The Czechoslovak Legion fought on the side of the Entente. Its goal was to win support for the independence of Czechoslovakia. The Legion in Russia was established in September 1914.
