What three countries unified and created a new currency in West Germany?

The Deutsche Mark (German: [ˈdɔʏtʃə ˈmaʁk] (About this soundlisten), "German mark"), abbreviated "DM" or "D-Mark" [ˈdeːˌmaʁk] (About this soundlisten), was the official currency of West Germany from 1948 until 1990 and later the unified Germany from 1990 until 2002. It was first issued under Allied occupation in 1948 to replace the Reichsmark, and served as the Federal Republic of Germany's official currency from its founding the following year until the adoption of the euro. In English it is commonly called the "Deutschmark" (/ˈdɔɪtʃmɑːrk/); this expression is unknown in Germany.[citation needed] The Germans usually called it D-Mark when referring to the currency, and Mark when talking about individual sums.[citation needed]

In 1999, the Deutsche Mark was replaced by the euro; its coins and banknotes remained in circulation, defined in terms of euros, until the introduction of euro notes and coins on 1 January 2002. The Deutsche Mark ceased to be legal tender immediately upon the introduction of the euro—in contrast to the other eurozone nations, where the euro and legacy currency circulated side by side for up to two months. Mark coins and banknotes continued to be accepted as valid forms of payment in Germany until 28 February 2002.

The Deutsche Bundesbank has guaranteed that all German marks in cash form may be changed into euros indefinitely, and one may do so in person at any branch of the Bundesbank in Germany. Banknotes and coins can even be sent to the Bundesbank by mail.[2] In 2012, it was estimated that as many as 13.2 billion marks were in circulation, with one poll showing a narrow majority of Germans favouring the currency's restoration (although a minority believed this would not bring any economic benefit).[3]

On 31 December 1998, the Council of the European Union fixed the irrevocable exchange rate, effective 1 January 1999, for German mark to euros as DM 1.95583 = €1.[4]

One Deutsche Mark was divided into 100 pfennige.

Explanation:

early human migrations are the earliest migrations and expansions of archaic and modern humans across continents and are believed to have begun approximately 2 million years ago with the out of africa migration of homo erectus. this initial migration was followed by other archaic humans including h. heidelbergensis, which lived around 500,000 years ago and was the likely ancestor of both denisovans and neanderthals. early hominids were said to have "crossed land bridges that were eventually covered in water" .

within africa, homo sapiens dispersed around the time of its speciation, roughly 300,000 years ago.the "recent african origin" paradigm suggests that the anatomically modern humans outside of africa descend from a population of homo sapiens migrating from east africa roughly 70,000 years ago and spreading along the southern coast of asia and to oceania before 50,000 years ago. modern humans spread across europe about 40,000 years ago.

the migrating modern human populations are known to have interbred with local varieties of archaic humans, so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.

after the last glacial maximum, north eurasian populations migrated to the americas about 20,000 years ago. northern eurasia was peopled after 12,000 years ago, in the beginning holocene. arctic canada and greenland were reached by the paleo-eskimo expansion around 4,000 years ago. finally, polynesia was peopled after 2,000 years ago, by the austronesian expansion.
