An anniversary is the date on which an event took place or an institution was founded in a previous year, and may also refer to the commemoration or celebration of that event. For example, the first event is the initial occurrence or, if planned, the inaugural of the event. One year later would be the first anniversary of that event. The word was first used for Catholic feasts to commemorate saints. Most countries celebrate national anniversaries, typically called national days. These could be the date of independence of the nation or the adoption of a new constitution or form of government. The important dates in a sitting monarch's reign may also be commemorated, an event often referred to as a "Jubilee".

In British heraldry, a coronet is any crown whose bearer is less than sovereign or royal in rank, irrespective of the crown's appearance. In other languages, this distinction is not made, and usually the same word for crown is used irrespective of rank (German: Krone, Dutch: Kroon, Swedish: Krona, French: Couronne, etc.) In this use, the English coronet is a purely technical term for all heraldic images of crowns not used by a sovereign, and implies nothing about the actual shape of the crown depicted. A Coronet is another type of crown, but is reserved for the lower ranks of nobility like Marquesses and Marchionesses, Earls and Countesses, Barons and Baronesses, and some Lords and Ladies. The specific design and attributes of the crown or coronet signifies the hierarchy and ranking of its owner.

A Royalty is the immediate family of a king or queen regnant, and sometimes his or her extended family.

However, in common parlance members of any family which reigns by hereditary right are often referred to as royalty or "royals." It is also customary in some circles to refer to the extended relations of a deposed monarch and his or her descendants as a royal family. A dynasty is sometimes referred to as "the House of ...". As of July 2013, there are 26 active sovereign monarchies in the world who rule or reign over 43 countries in all
