The regiment was founded as Infantry Regiment No. 155 in the course of the army expansion in 1897 on March 31, 1897 and had its garrison in Ostrowo . The III. Battalion was stationed in Pleschen . The regiment was subordinated to the 77th Infantry Brigade of the 10th Division .
It was formed from the IV (half) battalions of the 1st West Prussian Grenadier Regiment , the West Prussian Fusilier Regiment and the Lower Silesian Infantry Regiments No. 46 and No. 47 , initially with two battalions. 
On January 27, 1902, his birthday, Wilhelm II issued the Highest Cabinet Order (AKO) that the associations that had previously been run without a country team name were given a name extension for better differentiation and to establish tradition. Several associations of the same country team and the same type of troop should be distinguished by prefixed ordinal numbers. From this point on, the regiment was known as the 7th West Prussian Infantry Regiment No. 155.
