To define monarch simply: a monarch is the person who reigns over a monarchy. Kings and queens are the most familiar examples, but emperors, sultans, emirs, grand dukes and even the Pope are monarchs too. This page explains what the word means and the titles monarchs use. It also separates a reigning monarch from the people around the throne who are often mistaken for one.

TL;DR: A monarch is the single head of state of a monarchy, usually serving for life and often by inheritance. The title varies: king or queen, emperor, sultan, emir or grand duke, and in Vatican City, the Pope. Consorts, regents and heirs are not monarchs. The word comes from Greek for "sole ruler".

Define monarch: the core meaning

Dictionaries agree on the basic sense. The Cambridge Dictionary defines a monarch as a king or queen. Merriam-Webster gives a person who reigns over a kingdom or empire. It adds the sense of someone who holds supreme power. Britannica's article on monarchy describes the monarch as an individual ruler who acts as head of state.

Origin of "monarch"

Etymology of "monarch".

Status: Reviewed.

Note: "Monarch" comes from the Greek monarkhes, "sole ruler", from monos, "alone", and arkhein, "to rule". It entered English through Late Latin monarcha and is recorded from the 15th century. The butterfly sense came much later.

Sources: Merriam-Webster, "monarch"; Cambridge Dictionary, "monarch".

Titles that monarchs hold

A monarch's title depends on the country and tradition. The table lists the common ones with a current or historic example.

The line between two of these titles is drawn on the emperor vs king page.

Who is not a monarch

Several people close to the throne are often called monarchs by mistake.

When the label is disputed

Claimants who never reigned uncontested.

Status: Disputed. Depends on the list used.

Note: Some people held a monarch's title only briefly or without being accepted everywhere. In England, the Royal Family website lists Lady Jane Grey as a monarch for nine days in 1553. Most numbered lists leave her out. Such cases are shown as disputed records on this site's lists rather than settled either way.

How monarchs are addressed

Each title carries its own form of address. The table shows the forms used in English for some reigning monarchs.

Monarch, head of state and head of government

A monarch is always the head of state, the person who represents the country. Whether the monarch is also the head of government, the person who runs it, depends on the system. In Brunei the sultan also serves as prime minister, so he is both. In the UK, Sweden or Japan, the monarch is head of state only, and an elected prime minister heads the government. That split is what makes a monarch "ceremonial", as the ceremonial monarch page explains.

The longest-reigning monarchs of sovereign states

Some monarchs have reigned for seven decades. The table shows the longest proven reigns of monarchs of sovereign states.

Louis XIV came to the throne at the age of four. That helps explain his long reign.

Monarch as a general word

"Monarch" has other uses in English. It can mean anyone who holds supreme power in a field, as in "a monarch of the business world". It is also the name of the monarch butterfly, a large orange and black butterfly of North America. These senses come from the idea of a single dominant ruler.

How a monarch comes to the throne

Most monarchs inherit the throne under fixed rules of succession, such as the eldest child first. Some are elected, as in Malaysia and Vatican City. A few gained thrones by conquest or were installed by others. However they begin, their time on the throne is called a reign. Complete lists of monarchs by country start at the lists of monarchs index.

Monarch or dictator

A monarch and a dictator can both hold sole power. But they differ in how they get it and pass it on. A monarch holds a recognised royal office with fixed rules of succession, and the office outlives the person.

A dictator usually takes power by force or by ignoring a constitution. There is no agreed rule for who comes next. Some rulers blurred the line: Napoleon I turned a military dictatorship into a hereditary empire in 1804.

Verdict: how to define monarch

To define monarch: the person who reigns as head of a monarchy, usually for life. The title may be king or queen, emperor, sultan, emir or grand duke; in Vatican City it is the Pope. Consorts and regents sit near the throne but are not monarchs, unless they reign in their own right. For the system a monarch heads, see define monarchy and the monarchy hub.
