The 1st Life Grenadier Regiment (), designation I 4, was a Swedish Army infantry regiment that traced its origins back to the 16th century. It was merged into a new regiment in 1927. The regiment's soldiers were recruited from the province of Östergötland.
History
The regiment has its origins in fänikor (companies) raised in Östergötland in the 16th century. These units later formed Östergötland Infantry Regiment and Östergötland Cavalry Regiment which merged in 1791 and formed Life Grenadier Regiment. This regiment was split in 1816 creating 1st Life Grenadier Regiment and 2nd Life Grenadier Regiment.
The regiment was allotted in 1685. The regiment was given the designation I 4 (4th Infantry Regiment) in a general order in 1816. 1st Life Grenadier Regiment was then merged with 2nd Life Grenadier Regiment in 1928 to reform the old Life Grenadier Regiment.
