Cannons, You Are Welcome

Visitor welcome…Our doors are open and our cannons are waiting for you. We need only to see your lovely face in order to shoot 21 shots from the cannon as a warm tribute for your auspicious arrival.
Dear reader, have you asked yourself why 21 shots of the cannon are fired for kings and presidents as a welcome among countries? How was this habit identified as a protocol using 21 shots and not 10? So come with me to silence the cannon and the spotlight on this official greeting of the 21-gun salute.
A British study says that the number twenty-one symbolizes mental maturity, moderation chapters, and divine wisdom. That is why the number 21 was used as a symbol for welcome in a way that 21 shots are released from the cannon during the welcome ceremonies of important political people among the countries.
During the year 1800, the salute from the navies for the spots on the coast were 7 shots and 3 shots for each from the coast at the same time which means 21 shots and that goes to the nature of the cannon powder that was saved on the land in a better way than ships (gunpowder depends on sodium nitrates). But with time, they added other materials to gunpowder and it then depended on potassium nitrates more so ships began to shoot one by one shots.
Countries were levels at that time. For example, the British Emperor they used to shoot for him 101 shots and countries linked to Britain 21 shots. The number was descending according to importance to reach 31 shots in Afghanistan which was not linked to Britain.
Salute ceremonies differed from one place to another and protocol depended on them so Britain suggested to the United States that the salute will be 1 shot for another 1. That is why the United States used the 21 shots following Britain and this became the world protocol. We can mention that there is a 19 shot salute for the American deputies and 5 for the generals and 17 shots in Canada for the minister of defense.
Regarding the explanation and aim for this habit which became a world protocol, there is only one which is that releasing 21 empty cannon shots means that we finished all our savings for your sake and all our weapons are under your majesty.
The Lebanon Times comment is as follows: Lebanon is the only country that welcomes world presidents and kings without 21 cannon shots because they are the homeowners and we are the visitors…they are the ones who draw our policy.
The joke is: the officer told his soldiers be ready to shoot 21 shots from the cannon on the arrival of any president on his visit. One soldier said: sir if we shoot him from the first 1 do we continue the other 20 shots??
