Le dirham marocain (MAD) est la monnaie officielle du Maroc depuis 1958, date à laquelle il a remplacé le franc marocain (dont la valeur était fixée par rapport au franc français). Il est divisé en 100 centimes (santim) ou 20 rials dans l'ancienne partie française, l'ancien Protectorat espagnol du Maroc comptant lui 2 rials pour 1 dirham (1 rial = 50 cts).
Le dirham marocain a été l’unité monétaire principale du Maroc jusqu’en 1912, date du début du protectorat français sur le royaume, où le franc marocain l’a remplacé. Le dirham fut restauré à l’indépendance du Maroc en 1956.
A banknote (often known as a bill, paper money, or simply a note) is a type of negotiable instrument known as a promissory note, made by a bank, payable to the bearer on demand. When banknotes were first introduced, they were, in effect, a promise to pay the bearer in coins, but gradually became a substitute for the coins and a form of money in their own right. Banknotes were originally issued by commercial banks, but since their general acceptance as a form of money, most countries have assigned the responsibility for issuing national banknotes to a central bank. National banknotes are legal tender, meaning that medium of payment is allowed by law or recognized by a legal system to be valid for meeting a financial obligation. Historically, banks sought to ensure that they could always pay customers in coins when they presented banknotes for payment. This practice of "backing" notes with something of substance is the basis for the history of central banks backing their currencies in gold or silver. Today, most national currencies have no backing in precious metals or commodities and have value only by fiat. With the exception of non-circulating high-value or precious metal issues, coins are used for lower valued monetary units, while banknotes are used for higher values.
