In 1799 French revolution troops invaded Switzerland. When in 1803 Napoleon withdrew his army, Fribourg reorganised its military system. Thus, in 1804 the ,Freikorps' was founded which wore the same blue uniform as the contemporary contingent of Fribourg grenadiers.
 

The Fribourg troops participated in the Swiss neutrality protection campaigns of 1805, 1812, 1813 and 1815. The highlight of these activities was the occupation of Geneva in 1814 by Fribourg and Solothurn to prevent French encroachment. This occupation was the first step towards Geneva's joining the Swiss Confederation. During internal disturbances, the Fribourg troops were also successfully deployed, e.g. 1830 in Fribourg itself, 1831 in Basel and Neuenburg and 1839 in the Valais as well.

When in 1914 Geneva celebrated its hundredth anniversary of joining the Swiss Confederation, the authorities of the city asked the Canton of Fribourg to reconstruct the detachment of the Fribourg troops in the old blue uniforms of 1814. Enthusiastically some of the participants of this historical delegation decided to found the Fribourg contingent as an association for the keeping of military tradition. The number of active members was set at 80, in memory of the 80 Fribourg grenadiers who fell on 10 September 1792 in Paris when defending the Tuileries.
 

In the decision of 2 October 1964, the Fribourg Council of State named the contingent of the Fribourg grenadiers Guard of Honour of the Fribourg Government. The grenadiers are armed with guns from 1774/8, the bayonets and sabres are taken from museums. They fire a salvo in accordance with the military regimentation of 1790.
 

They are proud to serve their country, their canton and their city according to the ancient motto of ,honour and fidelity'.
 

The Grenadiers participate in historical and military manifestations both in Switzerland and abroad.
