Swedish name: Gotlands regemente, I18
During the Swedish - Russian war of 1808 - 1809, the Swedish Island of Gotland was invaded by Russian troops in 1808.
After the war, in 1811, a defense district unit was established at Gotland called the Gotland National Conscripts (Gotlands nationalbeväring).
It was based on active service of the population of Gotland. Every male between the age of 15 (later 18) and 50 were obliged to do service. Between the age of 50 and 60 they were obliged to assist with military fieldwork.
The conscript unit was organized in three artillery companies of 90 men each, armed with eight 6-pound and eight 12-pound guns.
Soldiers in the age between 15 and 30 served in the Rifle Corps. The Rifle Corps was organized in 16 companies of 150 soldiers each.
Soldiers in the age between 30 and 45 served in the Infantry Corps. The Infantry Corps was organized in 20 companies of 150 soldiers each.
Soldiers in the age between 45 and 50 served in the Reserve Corps. The Reserve Corps was organized in 7 companies of 150 soldiers each. They were only armed with pikes.
In total there were 6,781 soldiers in the Conscript Corps at Gotland.
The responsibilities for the Corps were to defend Gotland. They were not suppose to be used anywhere else. The first commander of the Corps was Vice Admiral Rudolf Cederström.
In 1861 the Corps were formed in 3 battalions, the North Battalion with 6 companies, The Mid Gotland Battalion with 7 companies and the South battalion with 8 companies.
In 1887 the Gotland National Conscripts Corps was organized into a regiment and received the name the Gotland Infantry Regiment  (Gotlands infanteriregemente, I27). A part of the Gotland National Conscripts also formed the Gotland Artillery Corps (Gotlands artillerikår).
Between 1928 and 1937 the Infantry regiment was reduced into a corps with the name the Gotland Infantry Corps (Gotlands infanterikår, I18).
In 1937 the unit once again was organized into a regiment, the Gotland Infantry Regiment.
In 1963 the infantry regiment was converted into an armored (tank) regiment and received the name the Gotland Regiment (Gotlands regemente, P18).
In 1915 the Gotland Infantry Regiment was the first regiment in Sweden with a machine gun company.
Location of the primary Garrison of the Regiment: From 1905, Visby. Training camp: Stånga malm, Blekväten and Vallstena rum. (http://www.hhogman.se/regiments_infantry-4.htm#Gotlands-regemente_I18)
