The traditional association of the regiment is the 1st Kurhessian Infantry Regiment "Kurfürst" , which was merged in 1789 from the Landgrave Hesse-Kassel Leib-Regiment-Infanterie and the regiment "Landgraf" under the name "Leibregiment-Infanterie". The Leib-Regiment-Infanterie formed the 1st Battalion, the Regiment "Landgraf" the 2nd Battalion. In 1803 the Leib-Regiment was named "Elector" and was given leave of absence by the Elector in 1806 when the French occupied Hesse-Kassel. It was not until 1813 that the regiment was reactivated as the “Elector” regiment. In the German Confederation the regiment was named 1st Line Infantry Regiment (1821), 1st Line Regiment "Kurprinz von Hessen" (1824), Leib-Regiment (1831), 1st Infantry Regiment, Leib-Regiment (1835), 1st Infantry Regiment "Kurfürst" (1856).
After the annexation of Kurhessen by Prussia after the German War in 1866, 21 officers and 520 NCOs and men joined the new regiment as a trunk to the new regiment, which was topped up by companies from various Prussian regiments. 
Reorganization after the German War 1866
In the German War of 1866 , the Elector, who was very pro-Prussian and unwilling to go to war, felt compelled to mobilize against Prussia after the federal execution was declared . However, almost the entire Hessian army was designated as the garrison of the Mainz fortress . There was almost no hostility between the two armed forces.
However, since Hessen-Kassel stood in the way of Prussia's expansion efforts, the state was annexed by Prussia together with the Duchy of Nassau , which was occupied by Prussia in July 1866, and the Free City of Frankfurt as the province of Hessen-Nassau . The Hessian troops were integrated into the Prussian army.
On October 30, 1866, the regiment was reorganized as the 1st Hessian Infantry Regiment No. 81 . For this purpose had to submit:
- the King Grenadier Regiment No. 7 the 8th, 13th, 14th companies
- the infantry regiments 47, 58 and 59 each the 13th – 15th. company
There were also 21 officers and 520 crews of former Kurhessian soldiers.
To reinforce other units, the following had to be given:
- on April 1, 1881, the 11th Company to Infantry Regiment No. 97
- on April 1, 1887, the 8th Company to the Fusilier Regiment No. 80
- on October 1, 1890, the 6th Company to Infantry Regiment No. 145
The regiment was later called Infantry Regiment Landgraf Friedrich I. von Hessen-Kassel (1st Kurhessisches) No. 81 and from 1909 1st Kurhessisches Infantry Regiment No. 81 .
The regiment belonged to the 42nd Infantry Brigade of the 21st Division in the XVIII. Army Corps and was initially stationed in Mainz. After the war of 1870/71 it came to Frankfurt am Main , where it was housed in the rooms of the former Carmelite monastery until 1879 . Due to the limited space in the Middle Ages, parts of the troops were quartered in private houses until 1879 . The III. Battalion was detached to Kassel until 1870, from 1870 to 1872 to Kastel and from 1872 to 1880 to Fulda .
In 1880 the regiment moved into the Gutleut barracks in Frankfurt am Main, which were built from 1877 to 1879 according to plans by Bruhns and Zacharias .
The regiment was part of the 14th Division and took part in the siege of Metz from August 19 to October 27, 1870 . The 1st Battalion fought on August 26 at La Grange aux bois.

Since there was still widespread anti-Prussian resentment among the citizens of the former Free City of Frankfurt, which was annexed in 1866, the regiment was given police powers. On April 21, 1873 six companies of the regiment violently put down the Frankfurt beer riot . There were 20 fatalities, including a woman and a ten-year-old boy. On the regiment's side, a lieutenant's head injury from being thrown from a stone was the worst injury.
On August 1, 1914 at 6.15 p.m. the regiment received the order to mobilize , which began on August 2. Within five days it reached its intended war strength by calling up reservists . On August 7th, the regimental staff and the MG company, on August 8th, the three battalions moved by train to Kahren . The soldiers were bid farewell by Prince Friedrich Carl of Hesse and Queen Sophie of Greece, among others.  Together with the other troops belonging to the 4th Army under Albrecht Herzog von Württemberg , it marched against the Luxembourg border.

The regiment was demobilized through the Wetzlar liquidation center until May 5, 1919 and finally dissolved. The formation of a volunteer battalion had already started in January 1919, which then became the 2nd battalion of the "Hessen-Nassau" Freikorps. This became the 2nd battalion of the Reichswehr Infantry Regiment 22 with the formation of the Provisional Reichswehr . 
The tradition in the Reichswehr was adopted by the 10th Company of the 156th Infantry Regiment in Kassel by decree of the Chief of the Army Command, General of the Infantry Hans von Seeckt , on August 24, 1921 .
