History and origins

By the end of the

period, a group of "companies" was referred to as a "column" of an army. According to Raymond Oliver, around 1500, the Spanish began explicitly reorganizing part of their army into 20 ''colunelas'' or columns of approximately 1000-1250 soldiers. Each ''colunela'' was commanded by a ''cabo de colunela'' or column head. Because they were crown units, the units were also confusingly called ''coronelas,'' and their commanders ''coronels.'' Evidence of this can be seen when

at militar.org.ua (in Spanish, unspecified authorship) Later in the 16th century, the French army adopted this organizational structure, renaming ''colunelas'' regiments. On the other hand, they simply Gallicized ''colunela'' to the French ''colonel'' and pronounced it as written. The English then copied the unit and rank from the French. However, for reasons unknown, the English adopted the Spanish pronunciation of ''coronel,'' and after several decades of use shortened it to its current two-syllable pronuciation "kernel." ''Colonel'' is linked to the word ''column'' (from

With the shift from primarily mercenary to primarily national armies in the course of the 17th century, a colonel (normally a member of the aristocracy) became a holder (German ''Inhaber'') or proprietor of a military contract with a sovereign. The colonel purchased the regimental contract—the right to hold the regiment—from the previous holder of that right or directly from the sovereign when a new regiment was formed or an incumbent was killed. As the office of colonel became an established practice, the colonel became the senior captain in a group of companies that were all sworn to observe his personal authority—to be ruled or regimented by him. This regiment, or governance, was to some extent embodied in a contract and set of written rules, also referred to as the colonel's regiment or standing regulation(s). By extension, the group of

In French usage of this period, the senior colonel in the army or, in a field force, the senior military contractor, was the colonel general and, in the absence of the sovereign or his designate, the colonel general might serve as the commander of a force. The position, however, was primarily contractual and it became progressively more of a functionless sinecure. (The head of a single

Colonel-in-chief

In many modern armies, the regiment has more importance as a ceremonial unit or a focus of members' loyalty than as an actual battle formation. Troops tend to be deployed in battalions (commanded by a lieutenant colonel) as a more convenient size of military unit and, as such, colonels have tended to have a higher profile in specialist and command roles than as actual commanders of regiments. However, in Commonwealth armies, the position of the colonel as the figurehead of a regiment is maintained in the honorary role of "colonel-in-chief", usually held by a member of the royal family, the nobility, or a retired senior military officer. The colonel-in-chief wears a colonel's uniform and encourages the members of the regiment, but takes no active part in the actual command structure or in any operational duties.

Colonel of the Regiment

The title Colonel of the Regiment (to distinguish it from the military rank of colonel) continues to be used in the modern British Army. The ceremonial position is often conferred on retired general officers,

may also be appointed to the ceremonial position. When attending functions as "Colonel of the Regiment", the titleholder wears the regimental uniform with rank insignia of (full) colonel, regardless of their official rank. A member of the Royal Family is known as a Royal Colonel. A Colonel of the Regiment is expected to work closely with a regiment and its Regimental Association.

Colonel as highest-ranking officer

Some military forces have a colonel as their highest-ranking officer, with no 'general' ranks, and no superior authority (except, perhaps, the head of state as a titular commander-in-chief) other than the respective national government. Examples include the following (arranged alphabetically by country name): * Antigua and Barbuda Defence Force, Antigua and Barbuda (170 personnel) * Public Force of Costa Rica, Costa Rica (about 8,000 personnel) * Iceland Crisis Response Unit, Iceland (100 personnel, employed only for peacekeeping duties) * Armed Forces of the Libyan Arab Jamahiriya, Libya (commands all the Armed Forces – Muammar Gaddafi until 2011) * Military of Monaco, Monaco (two branches, with a total of about 250 personnel) * Suriname National Army, Suriname (1,800 personnel) (up to 19 June 2020) * Military in Vatican City, Vatican City (110 personnel – the Pontifical Swiss Guard, Swiss Guard) {, class="wikitable" style="text-align: center" , - ! colspan="6", Rank insignia for a colonel in several nations which have no higher military rank , - ! rowspan=2 , Iceland ! colspan=2 , Monaco ! rowspan=2 , Vatican City , - !
