Both the brigade and division were disbanded in 1919, shortly after the end of the Great War. However, the brigade was reformed, now as the 198th Infantry Brigade, in the Territorial Army shortly before the outbreak of the Second World War in 1939, as part of the expansion of the Territorial Army when war with Nazi Germany seemed inevitable. It was again assigned to the 66th (East Lancashire) Division. However, the 66th Division was disbanded in June 1940 shortly after the British Expeditionary Force (BEF) was evacuated from Dunkirk. After the disbandment of the 66th Division, the brigade was independent for six months before joining the 54th (East Anglian) Infantry Division until it was disbanded near the end of 1943. The 8th King's Regiment (Liverpool) and the 6th Border Regiment were retrained as Beach groups for the upcoming invasion of France and the 7th Borders were transferred to the 222nd Brigade (later 213th Brigade) and the 198th Infantry Brigade ceased to exist and was not reformed in the Territorial Army after the war.
