In 1804-1806 France had 30 regiments of dragoons, more than any other cavalry. (There were only 12 regiments of cuirassiers and 10 regiments of hussars, for example.) Thus this is not surprising that finally - in 1806 - the Regiment of Guard Dragoons was established.
“Art XVIII - Each regiment of dragoons of the line will provide, this year, for the formation of the Guard Dragoons, 12 men having at least 10 years of service. The Emperor will name the officers: the regiments of horse grenadiers and horse chasseurs will provide the NCos and sergeants. 2/3 of the officers will be provided by the horse grenadiers and chasseurs; the 1/3, by the thirty dragoon regiments. ... “Art. XIX - Two squadrons of dragoons will not be organized, this year; next year a new call will be made for 10 men to form the two other squadrons."
The other requitements were:
