[1] On 21 July 1615, Captain Wilhelm von Kalckumb raised the Mark Life Company (Märkische Leib-Kompagnie) in the Margraviate of Brandenburg.

That year, the first regimental chef was assigned, Oberst Georg Bernhard, Freiherr von Pöllnitz.

There 5 men of the regiment received the Pour le Mérite, Prussia's highest military honour.

On 6 May 1757, the regiment lost two thirds of its strength (22 officers and 1,168 men) during the failed Siege of Prague.

[2] In 1758, the regiment guarded King Frederick's headquarters during the Invasion of Moravia and fought at the Battle of Jenwitz (10-11 October).

[5] During the French Revolutionary Wars, the regiment was not mobilised and subsequently not included in the Duke of Brunswick's Army, instead remaining on garrison in Brandenburg.

[8] In addition, an invalid company with 40 to 60 men was organised in each regiment, led by the commander of the depot battalion.

The uniform of the invalid companies consisted of a blue coat with cuffs and collars of the regimental colour.

They now consisted of:[9] twelve Officers, twenty-six NCOs, one Drum Major, eight Drummers, eight Surgeons and 480 x Soldiers, for a total of 535.

[citation needed] When the Prussian Army was mobilised for war on 9 October 1806, it was split between three major groups: the Advance Guard under General Frederick Louis, Prince of Hohenlohe-Ingelfingen, the Field Army commanded by King Frederick Wilhelm III and General Charles William Ferdinand, Duke of Brunswick-Wolfenbüttel, and Generalmajor Anton Wilhelm von L'Estocq's East Prussian Corps.

Along with the Grenadier Battalion, the regiment formed part of the Field Army and was present at the disastrous Battle of Auerstadt.

[10] The regiment along with the remainder of the army and grenadier battalion was decimated and fell back into Brandenburg.

The regiment then, albeit significantly reduced, fought at Weissensee, Greussen, Nordhausen, Ellingen and finally at the Battle of Ratekau where it surrendered and was subsequently disbanded.

The 3rd Battalion was reformed from the depot at the same time as the mobilisation and remained in Berlin till November when it joined the rest of the regiment at the Battle of Lübeck.

[15] During the regiment's history, its depot and headquarters garrison was Berlin in Neumark, while the grenadiers were in Strausberg, Brandenburg.

[5] Prussian Infantry regiments before 1806 had two official types of 'regimental colours', the Life Flag, which consisted of a white field and silver decorations.

The orange medallion had a black eagle and a white scroll bearing the gold motto "Pro Gloria et Patria", "For Glory and Fatherland".

The white medallion had a black eagle surmounted by an orange scroll with the same model as above in gold.

Prussian clue collarless coat had 2 x silver embroidered buttonholes under the lapels and one both sides of the rear waist.

Metallic embroidery of silver braid thread and white silk on red cloth was 29mm wide.

The metallic buttonhole lace of silver braid and white silk on blue cloth was 34mm by 83mm.
